Abstract:

A new species of the genus Ctenosciara Tuomikoski, 1960 is here described based upon a single specimen, obtained from collectings in the garden at Museum Alexander Koenig in Bonn. Ctenosciara alexanderkoenigi sp. n. differs from all other congeneric European species by its striking coloration and distinct male genitalia. However, DNA barcoding reveals associations with two specimens from New Zealand. Therefore a recent migration of Ctenosciara species from the Australasian Region, the likely center of origin of the genus, is discussed. A key to the European species of Ctenosciara is provided. Barcoding results reveale that Ctenosciara exigua is not clearly distinguished from Ctenosciara hyalipennis by its COI sequence (both share the same BIN BOLD:AAH3983) and that its species status may be questionable.

Abstract:

Three species of wing-reduced Sciaridae, obtained from pitfall trap material collected from Nothofagus forests in Victoria, Australia, were examined. The females, which were all very similar, do not belong to any of the wing-reduced sciarid genera known to us so far. They instead appear to be females of the genus Austrosciara Schmitz & Mjöberg, 1924, according to the original description and illustration, and one of the species appears to be conspecific with Austrosciara termitophila Schmitz & Mjöberg. The shape of the male hypopygium, as well as the tibial organ of this species in both sexes show typical features of species previously classified as Ctenosciara Tuomikoski, 1960. The genus Ctenosciara Tuomikoski, 1960 n. syn. has therefore to be considered a junior synonym of Austrosciara Schmitz & Mjöberg. A further species described as Austrosciara pedibusa sp. n., based on female specimens, is typically characterized by a deep sensory pit on the basal segment of the palpus. The female of a third species, listed as Austrosciara sp., is illustrated as well.

Abstract:

Fluctuations in the distribution and abundance of demersal fishes collected by otter trawl on the continental shelf of Ubatuba were examined over a two-year sampling period, in an area up to 50 m depth. A total of 111 species were collected. Seasonal and annual fluctuations in species abundance were related to differences in the distribution of Coastal Water and South Atlantic Central Water masses. The demersal fish fauna in the area was divided into three ecologically distinct communities: Tropical Sciaenid, Subtropical Sciaenid, and Gerreid-Haemulid. The most important one is the Tropical Sciaenid Community, characterized by Ctenosciaena gracilicirrhus, Paralonchurus brasiliensis, and Cynoscion jamaicensis.

Abstract:

AbstractThe food habits of the South Pacific hake (Merluccius gayi) from Ecuadorian waters were studied by analysing 232 stomachs of specimens ranging from 23.4–83.1 cm in total length (TL). Fish was the most important prey group (Alimentary Index, %AI = 94), Ctenosciaena peruviana being the most represented prey species (%AI = 62.17). PERMANOVA analysis showed dietary differences between the smallest individuals (class I < 30 cm TL) and the largest (class IV 40–45 cm TL; class V ≥ 45 cm TL). In addition, spatial differences in dietary composition were found between the three sampled regions (Manabí, Santa Elena and Guayas). The results of this study indicate that the South Pacific hake is an opportunistic predator feeding on a wide variety of vertebrate and invertebrate organisms.

Abstract:

This study evaluated the population biology of Ctenosciaena gracilicirrhus (Perciformes: Sciaenidae) in a shallow non-estuarine coastal area of southeastern Brazil. Monthly samples were taken from October 2003 through October 2004, in two distinct areas at depths from 1 to 4 m. C. gracilicirrhus was generally among the most abundant fish species during the period. Its density was significantly higher in a single sampling month, May 2004, in the South area, which may be explained by its migratory behavior together with its preference for deeper areas. Such behavior may lead to bias in community estimates that use few or only seasonal samples. C. gracilicirrhus individuals ranged from 4.0 to 10.2 cm long, with a main mode from 7.5 to 9.0 cm and a significant decrease in mean size from June onward. The estimation of body growth parameters was compromised by this population feature. Similarly, the prey spectrum was difficult to determine because of the deteriorated condition of the stomach contents, although crustaceans were clearly the most important items ingested. Amphipoda was the only subgroup that could be identified more precisely, mainly by the construction of their tubes.

Abstract:

We sampled fish and measured environmental variables in the Sepetiba Bay, a tropical embayment at Southeastern Brazil. The aim was to assess environmental influences on distribution of four abundant species of Sciaenidae Micropogonias furnieri (Desmarest, 1823), Ctenosciaena gracilicirrhus (Metzelaar, 1919), Cynoscion leiarchus (Cuvier, 1830) and Menticirrhus americanus (Linnaeus, 1758) to test the habitat partition hypothesis. Samples were taken between June 1993 and July 1996, at three bay zones (outer, central and inner). Depth was the most important environmental variable to influence fish distribution, followed by transparency. M. furnieri showed significant negative correlation to depth, transparency and salinity, while C. gracilicirrhus showed the opposite situation. The highest densities of C. leiarchus occurred in the lowest temperature, while M. americanus did not showed preferences for any of the examined environmental variables. Spatial separation, mainly between M. furnieri and C. gracilicirrhus, seems to be the strategy developed to coexist in the Sepetiba Bay, with M. furnieri being more adapted to copy with harsh environmental conditions of the inner bay. The other three species, which use mostly the outer bay zone, seem to be restricted to more stable conditions, where influences from oceanic waters are more intense.

Abstract:

The aim of this study was to analyze the distribution and abundance of the fish fauna of Palmas bay on Anchieta Island in southeastern Brazil. Specimens were caught in the summer and winter of 1992, using an otter trawl at three locations in the bay. The specimens were caught in both the nighttime and daytime. Data on the water temperature and salinity were recorded for the characterization of the predominant water mass in the region, and sediment samples were taken for granulometric analysis. A total of 7 656 specimens (79 species), with a total weight of approximately 300 kg, were recorded. The most abundant species were Eucinostomus argenteus, Ctenosciaena gracilicirrhus, Haemulon steindachneri, Eucinostomus gula and Diapterus rhombeus, which together accounted for more than 73% of the sample. In general, the ecological indices showed no differences in the composition of species for the abiotic variables analyzed. The multivariate analysis showed that the variations in the distribution of the fish fauna were mainly associated with intra-annual differences in temperature and salinity, resulting from the presence of South Atlantic Central Water (SACW) in the area during the summer. The analysis also showed an association with the type of bottom and a lesser association with respect to the night/day periods.

Abstract:

Based on data collected during the project "The influence of the Santos-São Vicente estuarine system on the ecosystem of the adjacent continental shelf" (ECOSAN), from Nov/2004 to Mar/2006, the space-temporal distribution pattern of Sciaenidae larvae in relation to biotic and abiotic factors was investigated. Bongo net was used for sampling, aboard the R/V "Prof. W. Besnard" on the shelf, and the boats "Veliger II" and "Albacora" in the estuarine region. Twelve taxa were identified: Bairdiella ronchus, Ctenosciaena gracilicirrhus, Cynoscion spp., Isopisthus parvipinnis, Macrodon atricauda, Micropogonias furnieri, Menticirrhus spp., Nebris microps, Ophioscion punctatissimus, Paralonchurus brasiliensis, Stellifer rastrifer and Stellifer spp. Sciaenidae larvae were widespread on the continental shelf in both campaigns (frequency of occurrence >80%). They were most abundant in Mar/2006 (mean = 6.47 larvae.m-2; sd = 8.36) and least abundant in Sep/2005 (mean = 2.37 larvae.m-2; sd = 3.33). The average abundance in the estuarine region ranged from 0.12 larvae.m-2 (sd = 0.11) in Jun/2005 to 4.28 larvae.m-2 (sd = 1.99) in Nov/2004. Frequency of occurrence minimum occurred in Aug/2005 (50%) and the maximum in Nov/2004 (100%). The presence of Sciaenidae larvae in most locations and periods suggests that the reproductive process of this family in the region is continuous, spawning being more intense in the warmer months.

Abstract:

The demersal fish community of the Channel and shelf of São Sebastião (SP), on the southeastern Brazilian coast, was investigated during the summer of 1994. The sampling was carried out usinga bottom otter trawl at 26 stations located between 8 m and 65 m in depth. Ninety-three species of 40 families were identified in the area. Sciaenids were the most prominent in number of species, abundance, and weight. Ctenosciaena gracilicirrhus, Paralonchurus, brasiliensis, and Cynoscion jamaicensis dominated in the catches. Cluster analysis showed three major groups of species and three groups of sites. The first group was composed of species found in the Channel and shallower areas of the inner shelf, the second of species associated with the inner shelf «50 m depth), and the third group of species fTom the outer shelf (> 50 m depth). Environrnental variables considered in Canonical Correspondence Analysis (CCA) explained 51 % of the variation in the species data. Bottom water temperature was the most important variable selected by CCA, accounting for 21% of the explainable variance. The results revealed that structure of the ichthyofauna was associated with water mass distribution. During the period studied, the area was occupied by the warm Coastal Water (CW), but cold South Atlantic Central Water (SACW) was detected over the bottom or the outer shelf, influencing the distribution and abundance ofthe main species.

Abstract Gasalla, M. A., Rodrigues, A. R., and Postuma, F. A. 2010. The trophic role of the squid Loligo plei as a keystone species in the South Brazil Bight ecosystem. – ICES Journal of Marine Science, 67: 1413–1424. The issue of whether loliginid squid can influence the average structure of marine ecosystems in a keystone role, i.e. a strong effect with relatively low biomass, has not yet been examined. Here, the diet of Loligo plei in inner shelf waters of the South Brazil Bight was examined, as a first step, based on the stomach contents of 2200 squid hand-jigged in shallow water (<30 m) and taken as bycatch of shrimp trawlers in deeper water (30–100 m). Diet varied by size, season, and fishing zone. Stomachs were not empty in ∼12%, with more empty during winter. The range of mantle lengths of squid caught by jigging (101–356 mm) appeared to differ from the squid trawled (30–236 mm), and the diet also differed. Food categories recorded in deeper water did not include amphipods or polychaetes, but in both fishing areas, fish were the most common prey. The fish prey identified included Trachurus lathami, small pelagic species, trichiurids, and Merluccius hubbsi. Demersal species, such as Ctenosciaena gracilicirrhus, and flatfish were also present. An ecosystem network model is updated through which a mixed-trophic impact matrix and “keystoneness” indicators were calculated. Loligo plei represents an important link between pelagic and demersal energy pathways, with high indices of keystoneness.

Abstract:

The effect of the Orion shipwreck on fish assemblage distribution near the reef was studied to the northeast of Rio de Janeiro with six different fishing gears: gillnets, mid-water longlines, circular traps, rectangular traps, vertical longlines, and bottom trawling. The study consisted of a pre-monitoring survey four months before the shipwreck in the area (A) and in two control areas (B and C). After 36 months, a total of 56 species were caught in the Orion reef area, 49 in control area B and 59 in control area C. The similarity analysis, considering the number of fish caught during the nine surveys in the three study areas, clustered the pre-monitoring and first post-settlement surveys of the three sites. This occurred due to the low number of fish captured and the dominance of Trichiurus lepturus and Lagocephalus laevigatus. These results differed from all the other studies in the three areas due to the co-dominance of Ctenosciaena gracilicirrhus and Stephanolepis hispidus. Such spatial similarity shows the low influence of the Orion reef in the area after three years. Biomass values were 15% higher in the Orion reef area than in the control areas, representing an increase of up to 1.2 times in wet weight. The increment of fish communities is still insufficient for proposing sustainable fishery activity in the shipwreck area. The monitoring time (32 months) after the sinking of the Orion may be considered too short to assure that the wreckage had reached its maturity as an artificial reef, either as a fish attractor or producer.

Abstract:

Sciaridae (Diptera) from forest and mire habitats from three localities in central Finland were identified. The material consisted of 609 specimens belonging to 106 species. The following species were found as new to Finland: Bradysia subbetuleti, B. submoesta, B. subscabricornis, Corynoptera fera, C. furcifera, C. saetistyla, C. subsedula, Cratyna spiculosa, Leptosciariella helvetica, Lycoriella micria, Pseudolycoriella brunnea, P. nodulosa, Scatopsciara neglecta, Trichosia glabra and Sciara sp. n. (Menzel & Salmela, in prep.) and Ctenosciara exigua sp. n. The latter is described as new to science. Bradysia subbetuleti, Leptosciariella atricha, Leptosciariella tuberculigera and Lycoriella micria are redescribed. The occurrence of some rare or poorly known species is discussed, and the importance of peatlands for sciarid biodiversity in the boreal region is emphasized.
