“…In general, while the body weight of the male individuals of crayfish is greater, and their walking legs and their cheliped wider and longer, the females have a wider and longer abdomen (Romaire et al, 1977;Rhodes and Holdich, 1979;Harlıoğlu and Güner, 2006;Ibarra and Arana, 2012). It has been found in most of the studies done on A. leptodactylus in Turkey that due to the size of their walking legs and their weight, male individuals have a greater average length and weight compared to female individuals (Erdemli, 1982;Balık et al, 2005;Büyükçapar et al, 2006;Güner, 2006).…”

Although crayfish are not much consumed in Turkey, fishing of the freshwater crayfish, which are especially sought after in European countries, started in lakes Manyas and Apolyont (Uluabat) at the beginning of 1965. It gained importance with its increasing export volume (Berber and Balık, 2006). Statistics for the number of freshwater crayfish caught in Turkish inland waters were not routinely recorded until 1976, and the number of freshwater crayfish caught was given as 3.885 t for the first time in 1977 (TÜİK, 1976(TÜİK, -1979. Isparta and Bursa were the leading provinces catching freshwater crayfish in those years.Lake İznik is situated within the borders of the province of Bursa in the Marmara region. The lake, with a surface area of approximately 313 km 2 , has a maximum depth of 65 m and its elevation above sea level is 85 m. The length of the lake is approximately 32 km and the widest point is 12 km. It is the largest natural lake in the Marmara region and the fifth largest in Turkey. There are five streams and ground waters that feed the lake (Aktan and Aykulu, 2001). Lake İznik, which is eutrophic in terms of ecology, is quite rich in diversity of species of fish compared with many other lakes; apart from the crayfish, there are 19 species of fish in the lake (Özuluğ et al., 2005).After the occurrence of crayfish plague in Turkish inland waters, crayfish stocks in lakes İznik and Apolyont were also negatively affected, and commercial crayfish

South America is considered a world biodiversity hotspot, especially for freshwater ecosystems where there is significant biodiversity and endemism across different taxonomic groups. Native South American crayfishes are characterized by small range distributions, high levels of endemism and specific habitat requirements. Although this group may be considered one of the most threatened among South American freshwater crustaceans, IUCN Red List assessments for most of these species are ‘data deficient’. IUCN assessments are technical evaluations of species risk of extinction based on biological indicators of population features, thereby providing a ‘conservation status’ for each species based on common and international standards. Attempts to assess the conservation status of native South American crayfishes have been limited mainly owing to a lack of fundamental data and also misinterpretations of present information. Thus, a revision of the state of knowledge of native South American crayfishes (taxonomy, phylogeny and distribution, genetics, ecology and threats) was carried out coupled with IUCN assessments of conservation status. Globally, the lack of information on the biology of these species is still the major obstacle to making reliable conservation status assessments. For this reason, the Data Deficient (DD) category is still appropriate for many species. However, based on the Extent of Occurrence (EOO) and severely fragmented populations, number of locations and decline in area, extent or quality of habitat, it is recommended that some species (especially Virilastacus spp.) should be moved to threatened categories (VU, EN or CR). The data suggest that others are appropriately in the Near Threatened (NT) category, because they almost reach the thresholds for threatened categories. The assessment of conservation status is essential to support future conservation actions, especially for species allocated to threatened categories. This study has identified new species under threat and also areas for future study to provide relevant data for conservation assessment for ‘data deficient’ species.

The burrowing crayfish Parastacus pugnax (Poeppig, 1835) inhabits the flooded plains in the central part of Chile (32–38°S), where it coexists with another representaives of invertebrate fauna. The aim of this study was to give the first description based on exploratory data of invertebrates associated to P. pugnax habitats in the Araucanía region, Chile. For comparison, published data on two similar habitats without P. pugnax populations were considered as outgroups. The obtained results revealed marked differences in species composition among sites with presence of P. pugnax, and without this species. A small number of species (1–5) was identified in the studied sites; Cladocera Simocephalus expinosus group was the most numerous and inhabited five of seven sites. Ecological and biogeographical topics were discussed.
