Abstract:

Interspecific and intraspecific aggressive interactions in the coexisting crayfish species Astacus astacus and Pacifastacus leniusculus were experimentally studied in the laboratory. Pacifastacus leniusculus strongly dominated aggressive interactions with similar-sized A. astacus in heterospecific pairs of juveniles and adults. Pairs of young-of-the-year were considerably less aggressive than the larger body-size groups, and in this size group neither species was aggressively dominant. The two species showed substantial differences in patterns of aggressive behaviour. A higher frequency of unilateral aggressive acts and much lower frequency and shorter duration of fights in P. leniusculus pairs indicate that this species is more inclined to establish a dominance order than A. astacus. The aggressive dominance of P. leniusculus over A. astacus indicates that P. leniusculus might be able to competitively exclude A. astacus when the species are competing for a limited resource.

Abstract:

Se detecta por primera vez en noviembre de 2015 la presencia del cangrejo señal, Pacifastacus leniusculus (Dana, 1852), en la Cuenca del río Segura. Esta introducción, probablemente, es resultado de una liberación intencionada o negligente realizada por particulares. La expansión de la especie podría tener serias implicaciones medioambientales, a tenor de los graves impactos sobre el hábitat y las especies nativas que el cangrejo señal ha tenido en muchas otras regiones. The occurrence of the signal crayfish, Pacifastacus leniusculus (Dana, 1852) in the Segura River Basin was detected for the first time in November 2015. Its presence is probably consequence of a deliberate or neglected introduction carried out by citizens. If it expanded in the Segura Basin, the signal crayfish could have serious environmental implications, based on the severe impacts on habitats and native species reported in other regions.

Abstract:

The reproductive strategies of species of non-indigenous crayfish make an important issue in astacological research. Although crayfish reproduction has been well studied, there is little information available on the occurrence of intersexuality. We report the first evidence of intersex in the signal crayfish, Pacifastacus leniusculus (Dana, 1852). An intersexual specimen was found among five tested signal crayfish. Morphology revealed both male and female genital openings, as well as male gonopods. The specimen superficially appeared male but contained both testes and ovaries, with an atypical dispersed structure. Sperm was obtained from this crayfish. Histology showed both spermatocytes and oocytes. The gonadosomatic index (GSI = 3.79) was considered as a morphometric parameter of the intersexual crayfish. The ova present in the intersex male raised its GSI to the three-fold of that of normal males.

Abstract:

Feeding behavior of carnivorous and herbivorous organisms is commonly explained in terms of nutritional requirements. However, feeding behavior of omnivorous organisms is difficult to predict and may not be based on nutritional requirements alone. To assess the plasticity of feeding behaviors exhibited by an omnivore, we conducted a feeding experiment using juvenile signal crayfish ( Pacifastacus leniusculus (Dana, 1852)), both alone and in the presence of conspecifics and predators. Crayfish were presented with three types of food (chironomids, mayflies, and woody debris) in experimental enclosures, and the food type consumed and time to consumption were recorded. Although the same overall food choice (chironomid larvae) was made in all trials, the time it took for the juvenile crayfish to make a food selection was longer in the presence of adult conspecifics (both male and female) and adult cutthroat trout ( Oncorhynchus clarkii (Richardson, 1836)). Food selection also took longer, although not significantly, in the presence of conspecific juvenile crayfish, and no changes in behavior were noted in the presence of young-of-the-year (YOY) cutthroat trout. The altered behavior of the juvenile crayfish observed in the presence of adult fish and crayfish can lead to context-dependent effects of this omnivore on its community. Ecologists must be increasingly aware that the feeding of omnivores may not be solely based on nutritional criteria.

Abstract:

Abstract Crayfish catches were conducted using traps in Lake Hańcza, which is the deepest lake in Poland. Two crayfish populations were found to co-exist in the lake: spiny-cheek crayfish (Orconectes limosus Raf.) and signal crayfish (Pacifastacus leniusculus Dana), which is a new species for this lake. Signal crayfish dominated the samples at 98.5% of the specimens caught. The crayfish occurred at depths of 1-10 m. The mean total body length of the male and female signal crayfish (TL) was 99.5 ± 17.8 mm and 96.5 ± 11.7 mm, respectively, while the average body weight (BW) was 38.7 ± 24.9 g and 26.8 ± 9.5, respectively. Chelae were damaged in 4.5% of the individuals. Fishing efficiency (catch per unit effort – CPUE) was 0.96 crayfish trap−1 night−1. Selected characteristics of the population and of individual signal crayfish from Lake Hańcza were compared with those of the two closest neighboring populations of this species in lakes Mauda and Pobłędzie. The confirmed occurrence of the relatively large signal crayfish population in Lake Hańcza excludes this lake as a possible site for native noble crayfish (Astacus astacus L.) restoration.

Abstract:

This study investigated the defensive responses of juvenile signal crayfish (Pacifastacus leniusculus, Dana) to two putative predators, perch (Perca fluviatilis, L.) and eel (Anguilla anguilla, L.), and attempted to determine the Importance of direct and indirect predatory effects on the distribution of newly independent Juvenile crayfish in a Swedish pond. Eels are thought to be more detrimental to crayfish populations than perch. Experiments using juvenile crayfish did not support this assertion. Visual and chemical stimuli elicited crayfish avoidance behaviour. This was most marked when both stimuli were presented together. Both predators elicited similar avoidance behaviour. Crayfish were less active by day, spending more time under shelter. Shelter provided by vegetation and substrata reduced crayfish mortality. Crayfish also avoided small non-predatory fish (Leucaspius delineates, Heckel). It is suggested that these fish indirectly increased crayfish mortality. Adult crayfish increased juvenile crayfish mortality but caused juveniles to be more active by day than at night. These responses illustrate the conflicting demands on crayfish defensive behaviour in multi-predator environments. Mechanical and visual stimuli elicited evasive behaviour. Crayfish evaded predatory strikes by perch and eels. The response to eels was delayed. Perch chased fleeing crayfish, and caught more crayfish than eels, which never chased prey. Initially, perch preyed on juvenile crayfish more rapidly than eels. Despite having distinct foraging behaviours, perch and eels produced similar crayfish mortalities. If eels are more detrimental than perch to crayfish populations, this may be a result of differences in size selective predation. The initial distribution of newly independent crayfish in a Swedish pond was influenced by the distribution of gravid female crayfish. Perch preyed on juvenile crayfish but were not a major factor determining crayfish distribution. Intraspecific competition and Invertebrate predation may have had a greater effect. Crayfish populations may be influenced by perch predation on yearling crayfish.

Abstract:

The major burrowing characteristics leading to, during and after burrow construction are described. Burrow initiation was significantly correlated to crayfish size; smaller individuals beginning construction more quickly. Field burrow morphologies, examined using an optic cable video camera, showed 92% to be simple with only a single opening (Length range 3.5 - 79.0 cm). Significant associations were found between the clay/sand content of stream bank sediments and crayfish burrow densities. Substrate selection experiments indicated a significant preference for artificial shelter over burrowing in clay for adult crayfish, and a significant preference for clay and artificial shelter over mud or gravel in juveniles. The rate of range extension of P. leniusculus along the Gaddesby Brook shows polynomial expansion i.e. the speed of new habitat colonisation is increasing each year. Juveniles, on the basis of burrow sizes and movements made by adult crayfish, are mainly responsible for this colonisation. Measurements of burrow water O[subscript 2], CO[subscript 2], ammonia and pH were made and showed lightly hypoxic conditions and elevated levels of ammonia in occupied burrows. Burrow irrigation rates were examined with average turnover rates being 14.8 1 h[superscript -1] for adults (mass range = 31.7 - 117 g). Crayfish movements were monitored by means of radio tracking. Results indicated that activity was greatest during and immediately following dusk and that crayfish activity was significantly less in winter than summer. Most individuals were position-fixed at the same burrow/shelter for the duration of radio tracking, a few made occasional large movements between stationary phases of between 2-8 days. The maximum distance recorded by any individual in one night was 89.6 m. During two flood events, all tagged animals maintained their pre-flood positions. Abdominal tags used to measure longer-term movements (over 2 years) gave an overall recapture rate of 19.0% (51 from 268) and generally showed that adult P. leniusculus remained in the same vicinity for in excess of 2 years. Hopefully this study will help in the control and management of P. leniusculus. For example, forecasts on preferred sites for population expansion and identification of sites vulnerable to bank damage can be deduced from substrate preferences. Furthermore, information on burrow construction, behaviour and irrigation rates may be relevant in biocide application and assessing the effects on bank stability. A knowledge of crayfish movement and activity is important for predicting time scale of spread and colonisation of new habitats.

Abstract:

Populations of non-native signal crayfish, Pacifastacus leniusculus, are damaging to UK native species and habitats though their populations are expanding with no coherent framework in place for their control. This is partly the result of a literature gap on the effect of trapping on non-native crayfish population structure which this thesis will explore in order to add to the European literature. Population size structure analysis has been facilitated via the creation of novel samplers and an in-depth analysis of the effect of aperture on the size/life stage of crayfish sampled. Smaller trap apertures, the addition of refuge material and novel samplers increased the catch of juvenile crayfish. Sex was indeterminable for up to 50% of juvenile crayfish, with juvenile sex ratios potentially biased towards females. Conditions on the River Lark did not limit populations, though temperature varied significantly between sites whilst substrata, pH and biological oxygen demand did not. Three years of trapping and juvenile sampling enabled population analysis at a site level. The population at Lark Head (professionally trapped), had a consistent size structure from 2010 to 2012, whilst individuals at Barton Mills (community trapped) and the Plough (untrapped), showed size decreases over time. The proportions of adult to juvenile individuals, and males to females, were similar at all three sites in 2011 & 2012. Catch per unit effort, decreased at all three sites with the greatest reductions at trapped sites. There is no evidence that catch sizes, or the proportion of juveniles, increased with trapping in spite of one site being trapped by the community since 2001 and another trapped by professionals since 2005. This refutes inferences that trapping causes an increase in biomass due to a reduction in the number of cannibalistic and dominant large males, with size and sex bias in traps also not corroborated.

Abstract:

Some aspects of the biology of Pacifastacus leniusculus and Astacus leptodactylus have been compared. The literature survey shows that considerably more studies have been carried out on P. leniusculus than A. leptodactylus. Although no major differences have been found in the morphology of appendages and mouthparts of the species, structural differences have been found in the abundance of setae on the second maxilliped, in the number of teeth on the mandibles and the crista dentata, and form of the chelipeds. Studies on the environmental tolerance of the species show that both species are able to survive in saline water for long periods of time but they can only increase in number in low salinities. Both species can survive over a wide range of temperatures, but they cannot tolerate temperatures of 34 °C after stepwise acclimation. Although the results do not show a clear difference in the tolerance of P. leniusculus and A. leptodactylus to low oxygen, there are some indications that A. leptodactylus is more tolerant of decreased oxygen tensions than P. leniusculus. By using a non-invasive heart beat monitor on crayfish it has been observed that the frequency of heart beats is extremely variable and can be affected by many factors, such as temperature and salinity. Juveniles of the two species can have a significant impact on plant and macroinvertebrate communities. The results also show that both species can have a negative effect on the recruitment of fish populations in freshwaters by eating fish eggs. Competition experiments show that both juveniles and adults of P. leniusculus are significantly more aggressive than those of A. leptodactylus. The results also show that A. leptodactylus would be eliminated by P. leniusculus if they met in a wild. Adults of the species prey on their juveniles, except the brooding females with stage 2s. This predation occurs in the presence of adequate nutrition. Non-predatory behaviour of the brooding females may indicate the presence of pheromones in the species. Reproductive efficiency of the populations of the species in Britain is as good as any studied elsewhere. In comparison to A. leptodactylus, P. leniusculus has more eggs, but smaller in size. Pleopodal egg development of the species can be reduced from seven months to three months with temperature acclimation, but photoperiod is not a factor in reducing pleopodal egg development. In both species sexual dimorphism was observed between males and females. Males of both species and females of P. leniusculus exhibit allometric or isometric growth during their lives but female A. leptodactylus exhibits isometric growth throughout. Comparison of body parameters shows that P. leniusculus can be considered as a morphologically better species to adapt to environmental conditions than A. leptodactylus because it has large and heavy chelae, and heavy body weight. Both species grow fast, but because P. leniusculus hatches earlier it has an advantage over A. leptodactylus and has bigger juveniles by the end of the first summer. In both species males produce significantly more claw meat than females. Although A. leptodactylus produces significantly more tail meat, males of P. leniusculus produce significantly more claw and total meat. Significant differences occur in the tail meat yield of female A. leptodactylus and in the claw meat yield of female P. leniusculus, but males produce similar amount of meat in winter and summer. The Swedish trappy is very effective method of catching both species over a certain size. Day and night catches show that both species are very active during the day and night.

Abstract:

Ontogenetic niche shifts generally coincide with changes in size, morphology, behavior, and/or feeding preferences during development, resulting in a shift in preferred habitat. In aquatic species, these ontogenetic niche shifts are often associated with habitat-dependent changes in competition and/or predation dynamics, expressed as a size-depth relationship where the larger-bodied adults occupy deeper habitats while the smaller-bodied juveniles primarily reside in shallower regions. While the influence of interspecific interactions on size-structured habitat occupancy has been well studied, few have examined the potential role of intraspecific agonistic interactions between size classes in ontogenetic niche shifts. A simulation model was developed to test whether the size-specific habitat occupancy observed in signal crayfish can be explained by the size-structured individual responses to agonistic interaction, where the smaller-bodied juvenile responds to the interaction with an escape movement, to avoid engagement and the risk of mortality or injury from the adult. The simulated movements of signal crayfish resulted in higher juvenile occupancy of riffles relative to pools reflecting a greater rate of escape from adults into riffles, away from the higher densities of adults in their preferred habitat (i.e. pools). This provides evidence that the juvenile escape response to size-structured, intraspecific, agonistic interactions may contribute to ontogenetic niche shifts.

Abstract:

Freshwater crustacean inland fisheries are typically confined to small local areas that are associated with bodies of water, like rivers and swamps. They are small-scale fisheries, enough to supply the requirements for local commercial use, and considered mainly as a subsistence resource for small fishing communities. As such, inland crustacean fisheries exemplify a subsistence opportunity for small countries with limited economic power, particularly rural communities. Crustaceans are a relevant protein source alternative to fish, and they are often also associated with local gastronomical and cultural identity. Data for the most commonly caught species are often unavailable since these fisheries exist in remote areas where government or institutional monitoring is limited, making it difficult to obtain reliable data about small-scale fisheries. Nonetheless, the captured species and the techniques used are widely diverse. In inland fisheries, the main target species are prawns from the genus Macrobrachium, gathered within the tropics all over the world. Natural fisheries of crayfishes in their native range exist on several continents, with Procambarus clarkii, Pacifastacus leniusculus, and Astacus astacus as the main commercial species. Some of them have also become a fisheries resource in areas where they were introduced. The only terrestrial crab fishery is for an anomuran, the coconut crab Birgus latro. The future of most of these fisheries depends in part on the health of the water sources threatened by contamination and unrestricted waterways jeopardized by the construction of dam-like structures that block the migration of some species to complete their reproductive cycles. The creation of regulatory policies is key for keeping the fishery activity self-sustainable because most of the exploitation depends on wild populations. There are some conservation efforts implemented thanks to the relevant gastronomical value of the species, as well as to economically sustain local communities in remote areas.
