Abstract:

Lesueurigobius friesii was collected in Eidsfjorden, Sognefjorden, Norway, extending its known distribution range north as the new northernmost locality of this species. Globally, the northernmost presence of gobies is along the coast of Norway. Their diversity along the Norwegian coast showed an evident latitude gradient of gobiid diversity with a clear decrease from south to north. The significant regression structural change was found at the 63/64° N latitude band followed by a 36.4% decrease in gobiid species diversity. The species traits of gobiids north of the regression breaking point and those restricted to the south of it were compared. The only significantly more frequent characteristic of species passing north of the regression breaking point is the large depth range that reach down to the shelf break. All species present north of the point, except Thorogobius ephippiatus (that barely passes it) belong to Oxudercinae (i.e. to Pomatoschistuslineage of that subfamily).

Abstract:

Lernaea cyprinacea is a non host-specific parasitic copepod known to infest many freshwater fish species. Outbreaks of infestations by this ectoparasite may cause mass mortality of parasitized fishes. L. cyprinacea has been found mostly on pelagic species. Records on small benthic fish species are less common. Especially rare are infestations of Gobioidei adapted to a benthic life style, with reports restricted to Asia and, in Europe, to the Ponto-Caspian region. Although it is cosmopolitan, L. cyprinacea has rarely been found in Italy. One of the few Italian localities with documented infestations is Lake Trasimeno, a lake with an economically important fishery. Although endoparasites of commercially interesting fish species in this lake are well documented, information about ectoparasites is rare. In May 2015, specimens of two gobioids − Knipowitschia panizzae and Pomatoschistus canestrinii − infested with L. cyprinacea were sampled at the south shore of Lake Trasimeno. Both gobies are not native to the lake. This is the first documentation of gobioid fishes as hosts of L. cyprinacea in Italy and in Europe (outside of the Ponto-Caspian region). Although both gobies are not optimal hosts (small size, short life expectancy) they have the potential to carry and to transmit the parasite in freshwater habitats, e.g. by unintentional introduction with fry of other fish species.

Abstract:

The Mediterranean, northeastern Atlantic, and inland freshwaters of Europe and the Ponto-Caspian region host a distinct fauna of gobiiform fishes, including the sand gobies (Pomatoschistus Gill and related genera), all of which have been clas-sified in the most diverse goby group, the family Gobiidae. Recent molecular phylogenetic analyses have suggested that the sand gobies are not gobiids, and are instead part of their sister clade Gobionellidae (Thacker and Roje 2011). Phylo-genetic analysis of Pomatoschistus in the context of both gobiid and gobionellid taxa indicates that Pomatoschistus is part of Gobionellidae, specifically the Mugilogobius lineage. Gobionellidae includes 93 genera, which are arrayed into four lineages (Stenogobius, Mugilogobius, Periophthalmus and Northern Pacific). These lineages exhibit variation in charac-ters of the jaw and suspensorium, including the shapes and relative positions of the palatine, quadrate, and ectopterygoid. The observations of the palatopterygoid complex in Gobionellidae of Harrison (1989) and Larson (2001) are supported and augmented. Gobionellidae generally exhibit suspensoria that are overall more elongated and gracile than those of go-biids: the palatine/ectopterygoid pair features a very short (Periophthalmus lineage) or elongate, pointed palatine (Mugi-logobius, Northern Pacific, and Stenogobius lineages), with a relatively slender ectopterygoid and a short quadrate articulation. In Gobiidae, the palatine extends about halfway along the length of the ectopterygoid, and the ectopterygoid generally features a large, flat articulation with the quadrate. Suspensoria of Pomatoschistus and relatives are similar to those of other taxa in the Mugilogobius lineage. Placement of Pomatoschistus and relatives in Gobionellidae rather than Gobiidae is significant in that it indicates that sand gobies are not closely related to other European gobies, and has impli-cations for any comparative evolutionary or biogeographic studies.

Abstract:

Abstract Recent invasions by non-native gobiid fish species that are ongoing in the Western European rivers Rhine and Meuse, will lead to interactions with native benthic fish species. Since both non-native gobiids and native benthic species are bottom dwelling species with a preference for shelter during at least part of their life cycle, it is likely that competition for shelter will occur between these non-native and native species when shelter is a limiting factor. To investigate the importance of this mechanism for species replacements, various habitat choice experiments were conducted between two common native benthic fish species (Cottus perifretum and Barbatula barbatula) and four invasive non-native gobiid species (Proterorhinus semilunaris, Neogobius melanostomus, N. kessleri and N. fluviatilis). The first series of single specimen experiments determined the habitat choice of each individual fish species. In a second series of competition experiments, shifts in habitat choice in comparison with the previously observed habitat choice, were determined when a native benthic fish species co-occurred with non-native gobiid species. Native C. perifretum displayed a significant shift in habitat choice in co-occurrence with the gobiids N. kessleri or P. semilunaris. C. perifretum was outcompeted and moved from the available shelter place to less preferred habitat types. During the competition experiments no change in habitat choice of B. barbatula was shown. Our study therefore suggests that competition for shelter is likely to occur in rivers invaded by N. kessleri and P. semilunaris at sites where shelter is limiting.

Abstract:

The common goby, Pomatoschistus microps (Krøyer), is a small, euryhaline gobiid fish which ranges along the coasts of continental Europe from the Mediterranean to Trondheim, Norway, and also penetrates into the Baltic Sea (Miller, 1973). This species, which can be very abundant, is generally distributed in estuaries, salt marsh and shore pools (Wheeler, 1969; Miller, 1971) and experiences a higher degree of environmental heterogeneity than most of the other European gobiids (Wallis & Beardmore, 1984a).

Abstract:

A recent study based on molecular biological data revealed that Gobius canestrinii (Ninni, 1883), a gobioid fish endemic to the Adriatic basin, has to be split in three lineages. The original description was based on populations from two distant localities in Italy and in Croatia respectively, the first representing one of these lineages, the second most likely belonging to another lineage. To fix the name of the species, we hereby designated a lectotype for Canestrini’s Goby.

Abstract:

Abstract The parasite fauna of gobiid fish of the Sukhyi Lyman, Black Sea, is described. Seventeen species of parasites are registered in the gobiids in the water body. The marine tubenose goby Proterorhinus marmoratus has the richest parasite fauna (12 species), the grass goby Zosterisessor ophiocephalus has the fewest number of parasite species (5 species). The microsporidian Loma sp. and ciliate Trichodina domerguei are recorded for the first time for gobiids in the north-western Black Sea. The core of the parasite fauna is formed by metacercariae Cryptocotyle spp. The core, secondary, satellite, and rare species in the parasite community of each host are described. Not only marine and brackish water parasites, but also limnetic species, namely metacercariae D. spathaceum, were registered in the Sukhyi Lyman that differentiates it from the many of localities in the north-western Black Sea.

Abstract:

Twelve new first records of species from two families are added to the list of known marine fishes from Malta based on laboratory study of material collected during fieldwork over a period of more than twenty years. The three new records of clingfishes (Apletodon incognitus, Gouania wildenowi, Opeatogenys gracilis) double the known diversity of Gobiesocidae for the area; the nine new records of gobies (Chromogobius zebratus, Gobius ater, Gobius fallax, Gobius gasteveni, Gobius roulei, Lebetus guilleti, Odondebuenia balearica, Speleogobius llorisi, Vanneaugobius dollfusi) increase by almost a half the known diversity of Maltese Gobiidae. The most enigmatic species reported is G. ater, for which the most recent published record is two decades old and based on specimens that had actually been collected back in the 19th century. Checklists of the Gobiesocidae and Gobiidae of Maltese waters are presented. Biodiversity and biogeographic implications of the present findings are discussed.

Full text

Abstract:

In recent decades, gobiid species have increased their distribution throughout Europe and now often represent the dominant genus along many rivers and canals. In this study, we assessed the role of tubenose goby (Proterorhinus semilunaris) as a prey species of native perch (Perca fluviatilis) in a lowland reservoir soon after their initial introduction in 1994 (sampling started 1998) and 17 years after establishment (2011–2012). We compare these data with perch diet composition from before introduction (1981–1982). Our data indicate that tubenose gobies quickly became the dominant species along the reservoir bankside, making them an attractive prey for ≥1 + perch. There was a clear increasing trend in the numbers of larger perch caught along the rip-rap, with the largest fish clearly specialising on gobies. As such, introduction of tubenose gobies has had a pronounced effect on food web and population dynamics along the littoral zone. While goby numbers appear to have dropped significantly in recent years, apparently due to predation pressure, further studies are needed to assess whether such changes have had any general impact on population and food web dynamics within the reservoir.

Abstract:

Specimens of the nudibranch genus Calma were observed under stones at two Croatian localities while feeding on gobiid eggs. Some ambiguous morphological features compared with the original descriptions of the known species of the genus, C. glaucoides and C. gobioophaga, hampered an easy identification. Genetic data (COI and 16S sequences) confirmed the distinction between the two species of the genus Calma, and allowed to unambiguously identify the Croatian specimens as Calma gobioophaga. This is the first record of this species for the Mediterranean and extends remarkably its distribution range. Finally, the eggs fed by the Croatian specimens have been taxonomically identified by using the 12S rDNA marker as Gobius cobitis.

Abstract:

AbstractSeasonal changes in occurrence, infracommunity composition and microhabitat distribution of the monogenean parasites of gudgeon Gobio gobio (L.) were studied during two years in the River Haná (Czech Republic). Altogether 212 specimens of gudgeon were examined and a total of 6456 specimens of eight monogenean species were recorded: Dactylogyrus cryptomeres, Gyrodactylus gobiensis, Gyrodactylus gobii, Gyrodactylus gasterostei, Gyrodactylus vimbi, Gyrodactylus markakulensis, Gyrodactylus sedelnikowi and Paradiplozoon homoion. The occurrence of monogeneans correlated with seasonal changes of water temperature. In 2001, gyrodactylids peaked in March and D. cryptomeres in May, whereas in 2002, gyrodactylids peaked in May and D. cryptomeres in July. The majority of specimens of all Gyrodactylus species were found on the fins; the remaining specimens of Gyrodactylus were located on the body surface and gills, and all Dactylogyrus and Paradiplozoon specimens were located on the gills. The microhabitat distribution of the monogeneans changed in relation to changing water temperature and intensity of infection.

Abstract:

Gobies (Gobiiformes: Gobiidae) are the most species-rich family of fishes in general, and the most abundant fish group in the European seas. Nonetheless, our knowledge on many aspects of their biology, including the population genetic diversity, is poor. Although barriers to gene flow are less apparent in the marine environment, the ocean is not a continuous habitat, as has been shown by studies on population genetics of various marine biota. For the first time, European marine goby species which cannot be collected by common fishery techniques were studied. The population genetic structure of two epibenthic species, Gobius geniporus and Gobius cruentatus, from seven localities across their distribution ranges was assessed, using one mitochondrial (cytochrome b) and one nuclear gene (first intron of ribosomal protein gene S7). Our results showed that there is a great diversity of haplotypes of mitochondrial gene cytochrome b in both species at all localities. Global fixation indices (FST) indicated a great differentiation of populations in both studied gobies. Our results did not show a geographic subdivision to individual populations. Instead, the data correspond with the model of migration which allow divergence and recurrent migration from the ancestral population. The estimated migration routes coincide with the main currents in the studied area. This matches well the biology of the studied species, with adults exhibiting only short-distance movements and planktonic larval stages.

Abstract The fish acanthocephalan fauna of Turkish waters is poorly known. In this study 8 fish species (Merluccius merluccius, Trachurus trachurus, Uranoscopus scaber, Gobius niger, G. cobitis, Scorpaena scrofa, Eutrigla gurnardus, Solea vulgaris) were collected from Gemlik Bay and examined for their acanthocephalan fauna. Four species not previously recorded in fish of Turkish waters were found: Solearhynchus soleae (Echinorhynchidae), Acanthhocephaloides propinquus, Paracanthocephaloides kostylewi (Arhythmacanthidae), and Longicollum pagrosomi (Pomphorhynchidae). The most common species was A. propinquus, a parasite that infects mostly gobiids (G. niger, G. cobitis). Longicollum pagrosomi was a new record for the Mediterranean basin.

Abstract:

Gobies (Gobiidae + Oxudercidae) are among the largest groups of extant marine fishes. Fossils of gobies are abundant since the Miocene, and many species have been reported so far. However, delimitation of fossil goby species is challenging because molecular markers and diagnostic traits such as the disposition of sensory head papillae are lost. This study provides, for the first time, an actualistic framework for the identification of fossil goby species. We focus on characters that can in principle be recognized in fossils, and evaluate their ability to discriminate between extant goby species based on statistical analyses. Using 14 extant species of Gobius and seven species of Pomatoschistus, we conducted otolith morphometry, elliptic Fourier shape analysis of otoliths using the package ‘Momocs’, conventional fish morphometry, and meristic counts. In addition, the otoliths of all species are depicted based on SEM images and briefly described. Otolith Fourier shape analysis proved to be most efficient in discrimination of species within both genera, Gobius and Pomatoschistus. Several characters used in the other approaches also worked well, but the results were variable, and the relative taxonomic significance of particular variables tended to change depending on the species under consideration. We propose otolith shape analysis as a powerful tool to explore ancient goby species diversity when samples with abundant fossil otoliths are present. Overall, the herein presented data will greatly facilitate delimitation of fossil goby species in future studies, and will consequently shed new light on the evolution of goby diversity and biogeography through time.

Abstract:

AbstractMetazoan parasite communities of two gobiids, Proterorhinus marmoratus and P. semilunaris, which are common small-sized fishes native for the Black Sea basin, were studied. The parasite component community of P. marmoratus is represented by 11 species (one monogenean, one cestode, five digeneans, two nematodes, and two acanthocephalans). P. semilunaris had 5 species (one monogenean, one cestode, one digenean, one nematode, and one acanthocephalan). Acanthocephaloides propinquus has a great tendency to join the infracommunity. The differences between the parasite component communities of two Proterorhinus gobies are explained by different quality of habitats and available intermediate hosts. The component community of parasites of P. marmoratus is formed by brackish-water and marine parasite species, and that of P. semilunaris consists of limnetic parasite species. The euryhaline G. proterorhini is the only parasite species found in both P. marmoratus and P. semilunaris. In both species of gobiids, the main abundant parasite species (A. propinquus in P. marmoratus and Nicolla skrjabini in P. semilunaris) infest the host by feeding on crustaceans.

Abstract:

The fish assemblages of rocky intertidal and subtidal (<3 m depth) habitats of the south-western Portuguese coast were sampled between May 1992 and November 1993, using traps, angling and hand-netting, to investigate their structure and seasonal dynamics. The main purpose of the study was to describe the patterns of prey availability for marine-feeding otters (Lutra lutra L., Mammalia) in south-western Portugal, and to compare these with other areas in Europe. A total of 475 fish of 14 species was captured over 150 d of trapping (788 trap-days), and 1575 fish of 15 species were captured over 24 d of angling (76.3h). Hand-netting was carried out occasionally, to supplement the observations from the other methods, and only 96 fish of seven species were captured. The three methods yielded different patterns of the fish assemblage: giant gobies (Gobius cobitis Pallas, 33.7%) and rock gobies (G. paganellus L., 22.9%) were the most frequently trapped fish; corkwing wrasse (Symphodus melons (L.), 81.2%) were the usual species caught by angling; shannies (Lipophrys pholis (L.), 42.7%) and Montagu's blennies (Coryphoblennius galerita (L.), 28.1%) were the most frequently netted species. Conger eels (Conger conger (L.)), giant gobies and shannies showed an uneven distribution along the coast, occurring most frequently in schist shelves, rather than in areas of large sandstone boulders. There was a large seasonal variation, with the catches of most species peaking in winter and early spring, including the majority of those most important in the diet of otters: conger eels, shore rocklings (Gaidropsarus mediterraneus L.), rock gobies and corkwing wrasse. This was also the period when the individuals of several species were heaviest.

Abstract:

The rock goby, Gobius paganellus one of the most common gobiid fish in Bizerta lagoon (north-east of Tunisia), is a gonochoric species that belongs to the Gobiidae family. This study provides the first detailed information of its reproductive biology in lagoon environments. Gobius paganellus was sampled monthly from January 2005 to December 2006 involving 1486 specimens. Total length distribution ranged between 38 and 125 mm. The maximum recorded total lengths were, respectively, 122 mm and 125 mm for female and male. Over the entire population, the sex-ratio was unbalanced in favour of females. According to months, a predominance of females sex-ratio was recorded during the spawning period while according to body size, males were dominating among larger size-classes. In both sexes, the variation of the gonadosomatic index (GSI) was independent of size. Macroscopic and microscopic examination of the gonads added to the monthly monitoring of gonadosomatic index and hepatosomatic index showed that gonads development begins in October and spawning period extends from December to March. The cyclic pattern of gonads development was determined by histology. Results indicated that G. paganellus exhibits a group-synchronous oocyte development. The sizes of first sexual maturity related to 50% of mature individuals were 78.3 mm (CI95: 77–84 mm) for males and 79 mm (CI95: 75–85 mms) for females. The discussion part underlined the impacts of some environmental factors and antropization of this lagoon on sexual cycle of G. paganellus.

Abstract:

A new genus and species of goby, Gymnesigobius medits sp. nov., is described from the western Mediterranean slope bottoms at the Balearic Islands. The new goby belongs to the Gobius-lineage (Gobiinae). Examination of the single known specimen exhibits a unique combination of morphological characters which could not be fitted to any known genus. Gymnesigobius gen. nov. is morphologically distinguished from all other genera in the Gobius-lineage by the following combination of characters: chin without fold or barbels; mouth terminal with anterior tip above horizontal level of lower eye edge; predorsal area and first dorsal fin base naked; pelvic fin anterior membrane well developed; head with anterior oculoscapular and preopercular canals, posterior oculoscapular canal absent; pores of head canals enlarged, e.g. pores α and ρ larger or of about the same size as interspaces to pore β; six transverse suborbital rows of sensory papillae, four continuous suborbital rows in front of row b, fifth row divided in three parts but in front of row b, sixth row just as superior part above row b and below pore α; longitudinal suborbital row b barely reaching forward to the vertical from posterior edge of eye. A full description of the new genus and species is provided. The new species, collected at a depth of between 344 and 364 m (mean depth of 354 m), is one of very few gobiid species found at bathyal depths.

Abstract:

Three species described and currently included in the genus Gobius from the Brazilian coast are herein discussed. Gobius uranoscopus Sauvage is regarded as junior synonym of Bathygobius soporator based on information on holotype deposited in Muséum National d’Histoire Naturelle, Paris; G. silveiraemartinsi Ihering, known only in Rio Grande do Sul was erected based on a short description, and type material is not available, but I considered that it is junior synonym of Ctenogobius shufeldti; Gobius boekeri Ahl, 1931, described from the coast of Pará, Brazil, is a junior synonym of Gobionellus oceanicus, as both taxa are virtually identical in meristic characters and presumable morphometric differences that Ahl used to substantiate the validity of his new species actually fall into the morphometric range observed in G. oceanicus specimens and may be attributable to individual variation and to the image quality by Ahl’s original description.

Abstract In the protected area ROSCI0229 Siriu were named three fish species of community interest: Gobio uranoscopus frici Vladykov, 1925, Barbus petenyi Heckel, 1847 and Cottus gobio Linné, 1758. Out of 193 fish collected in 2010, 49 were Barbus petenyi and 37 Cottus gobio. In the three monitored rivers (Buzău River, Siriu River, and Crasna River), Barbus petenyi was present in two of them and Cottus gobio was present in all of them. According to the analytical indices of population, frequency, numerical abundance and density we assessed a favorable population status for Barbus petenyi in Buzău River and a medium favorable population status for Cottus gobio in Buzău River and its tributaries Crasna River and Siriu River.

Abstract:

Invasion risk assessments are reliant on ecological data that assist the predictions of whether an introduced species will adapt to novel conditions. Data from the native range of potential invaders can thus assist these assessments. Here, the growth and reproductive characteristics of the Western tubenose goby Proterorhinus semilunaris, a Ponto-Caspian gobiid, were assessed in three natural lakes in their native range, as there are few extant data on these traits. Across the three lakes, the gobies were found in varying abundances. Sex ratios varied, with females significantly outnumbering males in only one lake, with equal sex ratios in the other lakes. The fish always showed a positive allometric growth, but had high variability in their somatic growth rates and relative body conditions between the lakes. Scale ageing revealed all populations comprised of individuals to four years old, with one lake having individuals to 5 years old. Reproductive characteristics, including size at maturity, gonado-somatic index and fecundity, did not differ significantly between the lakes. These data suggest that plasticity in aspects of their life history traits provides P. semilunaris with considerable adaptive capacity following their introduction into novel conditions.

Full text

Abstract:

The Ponto-Caspian region is an important source area for some invasive gobiid fishes. These fishes have colonised several freshwater ecosystems in Europe, as well as in North America. As knowledge on their habitat utilisation in their native range remains limited, the seasonal habitat uses of Western tubenose goby, Proterorhinus semilunaris and monkey goby Neogobius fluviatilis were studied in four natural lakes in the Marmara Region (NW Turkey). Habitat use of both species was highly variable between the lakes and seasons, with P. semilunaris showing higher plasticity. In general, the main habitats used by P. semilunaris were shallow waters in littoral areas that had vegetation cover, whereas N. fluviatilis consistently used sandy substratum in deeper waters that lacked vegetation. These results suggested there was high plasticity in the habitat utilisation of these two gobiids, especially in P. semilunaris, which potentially facilitates their ability to establish and invade novel environments. The habitats that are especially vulnerable to P. semilunaris invasion are medium size substrates which provide individuals with sufficient interstitial space for refuge. Waters providing differing habitats, such as sandy substrata, might inhibit their colonisation, but are potentially more vulnerable to N. fluviatilis invasion.

The ADONIS:CE tool has been used to build a backing management system model, based on these indicative fish species habitat needs, indicators for favourable conservation status, pressures and threats. This management system implementation in the field will favour the amelioration of lotic habitats and the ecological status recovering of two of the local fish species of conservative interest (G. kessleri and G. albipinnatus).

Full text

Abstract:

Plankton samples were collected on monthly cruises over 1 year from May 1983 to April 1984, to investigate composition, seasonality and distribution of ichthyoplankton in Port Phillip Bay. Fish egg numbers were dominated by the southern anchovy, Engraulis australis; clupeoids and gobiids were co-dominant larvae. Other common fish larvae were the cobbler, Gymnapistes marmoratus, greenback flounder, Rhombosolea tapirina, and callionymids. Egg abundances were highest in summer, resulting mainly from high abundances of E. australis eggs. Abundances of fish larvae were highest in summer and winter-spring. The summer period was dominated by clupeoid and gobiid larvae, together with callionymids, monacanthids, platycephalids, the blenny, Pictiblennius tasmanianus, the snapper, Chrysophrys auratus, and a number of rarer species. The winter-spring period was almost entirely dominated by four taxa: gobiids, G. marmoratus, R. taplrina and the long-snouted flounder, Ammotretis rostratus. Eggs of E. australis, Sardinops neopilchardus and A. rostratus, and larvae of all common taxa except monacanthids and C. auratus, were distributed widely throughout the bay. Abundance of eggs of E. australis at the mouth of the bay was significantly lower than within the bay proper. Larvae of P. tasrnanianus were significantly more abundant in the shallow, northern region of the bay than in the deeper, central region. Most monacanthid larvae were collected towards the mouth of the bay, whereas C. auratus larvae were only collected at stations well inside the bay. Analysis of winter samples revealed multispecies patchiness of fish larvae, and a positive correlation between larval abundance and volume of net zooplankton. Although juveniles of King George whiting, Sillaginodes punctatus, and yellow-eyed mullet, Aldrichetra forsteri, are abundant in Port Phillip Bay, larvae were virtually absent. It is proposed that these species spawn offshore, and that immigration into the bay occurs at a late larval-early juvenile stage not detectable by plankton sampling.

Full text

Abstract:

Acanthocephalans are polygamous parasites of vertebrates and some species are known to aggregate in sexual congress to mate. Such a reproductive behaviour could lead to male–male competition for access to females and could have consequences for sexual selection. We dissected 87 gobiid fish, Gobius bucchichii, harbouring 891 acanthocephalans, Acanthocephaloides propinquus. The parasites were sexed and their body sizes were measured. Testicular volume was also evaluated in 82 males in order to establish their phenotypic sexual investment in relation to the estimated sex ratio. We found that parasite intensity (i.e. the number of individuals/fish) was not correlated with fish size, but that parasite size was significantly related to host size. Our results showed that there was a significant relationship between the mean female body size and their number within one host. We found that when the percentage of male parasites in a host increased, presumably increasing male–male competition for access to females, males had a larger testicular volume. We discuss these results in terms of energy allocation, sexual and sperm competition. We conclude that competition for space should be less important for males than competition for access to females. Moreover, increasing testis size should confer advantages to males especially for their reproductive success when sperm competition occurs.

Full text

Abstract:

The fish otolith assemblages identified in the Zanclean sediments of Voutes section (Heraklion, Crete) are analyzed in order to estimate the depth of deposition. The assemblages indicate that Voutes area was in fact a coast inhabited by a neritic fish fauna with significant mesopelagic component, mostly Myctophids. The benthic and benthopelagic group exhibits great diversity. In the late Zanclean, the study area corresponds to a deep neritic environment, which gradually uplifts. At the end of the Zanclean, Voutes area becomes a very shallow coast, as shown by the increased contribution to the assemblage by members of the Gobiid family, as well as the notable presence of Bothidae. Thereafter, the area deepens again, as the shallow benthic-benthopelagic component significantly decreases. This is consistent with the appearance of Pteropods and reaches a peak during the deposition of diatomites at maximum depth. At the upper part of the section, the sea bottom depth decreases again to allow for the deposition of marls with various molluscs remains, where Gadids and Gobiids again reappear. Finally, the upper diatomitic horizon is characterized by a rather poor fish fauna. These observations allow reconstructing the evolution of Voutes coastal area during the latest Zanclean until the Piacenzian.

Abstract The length-weight relationship (LWR) parameters of Gobio insuyanus Ladiges, and Gobio microlepidotus Battalgil, which are endemic to Turkey, were estimated. The fish were caught by single-pass electrofishing with backpack electrofishing gear. The range for fork length and total weight and the LWR parameters including regression parameters (a, b, and their 95% CI) and the coefficient of determination (r2) were calculated for both species. The b values were 2.921 for G. insuyanus and 2.906 for G. microlepidotus. The length-weight relationships were statistically significant for both species (P < 0.001). An urgent species conservation plan is highly recommended for G. insuyanus in light of its narrow distribution area and the human impacts threatening its natural habitat.

Abstract:

Eight species of the Gobiidae were recorded in weekly samples taken between July 1972 and June 1977 from the intake screens of Oldbury Power Station in the inner Severn Estuary. Buenia jeffreysii, Aphia minuta, Gobius paganellus and Gobius niger occurred infrequently and Crystallogobius linearis was only common in the late spring and summer of 1975 and 1976. Pomatoschistus microps, which peaked in numbers in the winter, increased in abundance each year between 1972 and 1977. The most numerous gobies were those belonging to the Pomatoschistus minutus complex which were separated into P. minutus and P. lozanoi only between June 1974 and July 1975. Seasonal trends in the abundance of these two species were similar, with elevated numbers occurring between July and September 1974 and in January 1975. Gonadosomatic indices and other data indicate that the decline in numbers after the latter month represented an emigration to spawning areas further down the estuary or in the Bristol Channel. Although P. minutus attained a larger body size than P. lozanoi, both these species and P. microps typically had a one year life cycle with only a small number of individuals surviving for a further few months. The fecundity of P. lozanoi, which ranged from 410–2453 (mean 1270), was lower than that reported for P. minutus in this and other studies. Analysis of stomach contents showed that the diet of both species was similar, consisting predominantly of gammarids and mysids. While both species were infected with Ligula intestinalis, the incidence of infection and the parasite index was greater in P. lozanoi than in P. minutus.
