The Evolution of Crayfishes of the Genus Orconectes Section Limosus (Crustacea: Decopoda)
THE OHIO JOURNAL OF SCIENCE Vol. 62 MARCH, 1962 No. 2 THE EVOLUTION OF CRAYFISHES OF THE GENUS ORCONECTES SECTION LIMOSUS (CRUSTACEA: DECOPODA) RENDELL RHOADES Department of Zoology and Entomology, The Ohio State University, Columbus 10 The earliest described crayfish species now included in the Section limosus of the Genus Orconectes was described by Samuel Constantine Rafinesque (1817: 42). He reported the species, which he named Astacus limosus, "in the muddy banks of the Delaware, near Philadelphia." How ironical it now seems, that when Rafinesque located at Transylvania three years later and traveled to Henderson, Kentucky, to visit a fellow naturalist, John J. Audubon, he could have collected from the streams of western Kentucky a crayfish that he might have identified as the species he had described from the Delaware. We now know that these streams of the knobstone and pennyroyal uplands are the home of parent stock of this group. Moreover, this parental population on the Cumberland Plateau is now separated from Rafinesque's Orconectes limosus of the Atlantic drainage by more than 500 miles of mountainous terrain. Even Rafinesque, with his flair for accuracy and vivid imagination, would have been taxed to explain this wide separation had he known it. A decade after the death of Rafinesque, Dr. W. T. Craige received a blind crayfish from Mammoth Cave. An announcement of the new crayfish, identi- fied as "Astacus bartonii (?)" appeared in the Proceedings of the Academy of Natural Science of Philadelphia (1842: 174-175). Within two years the impact of Dr. Craige's announcement was evidenced by numerous popular articles both here and abroad. -

J. Black Sea/Mediterranean Environment Vol. 15: 47- 60 (2009) Freshwater and brackish water Malacostraca (Crustacea-Arthropoda) fauna of Sinop and Samsun and their ecology Sinop ve Samsun illeri tatlısu ve acısu Malacostraca (Crustacea-Arthropoda) faunası ve ekolojileri Mehmet Akbulut1*, M. Ruşen Ustaoğlu2, Ekrem Şanver Çelik1 1 Çanakkale Onsekiz Mart University, Fisheries Faculty, Çanakkale-Turkey 2 Ege University, Fisheries Faculty, Izmir-Turkey Abstract Malacostraca fauna collected from freshwater and brackishwater in Sinop and Samsun were studied from 181 stations between February 1999 and September 2000. 19 species and 4 subspecies belonging to 15 genuses were found in 134 stations. In total, 23 taxon were found: 11 Amphipoda, 6 Decapoda, 4 Isopoda, and 2 Mysidacea. Limnomysis benedeni is the first time in Turkish Mysidacea fauna. In this work at the first time recorded group are Gammarus pulex pulex, Gammarus aequicauda, Gammarus uludagi, Gammarus komareki, Gammarus longipedis, Gammarus balcanicus, Echinogammarus ischnus, Orchestia stephenseni Paramysis kosswigi, Idotea baltica basteri, Idotea hectica, Sphaeroma serratum, Palaemon adspersus, Crangon crangon, Potamon ibericum tauricum and Carcinus aestuarii in the studied area. Potamon ibericum tauricum is the most encountered and widespread species. Key words: Freshwater, brackish water, Malacostraca, Sinop, Samsun, Turkey Introduction The Malacostraca is the largest subgroup of crustaceans and includes the decapods such as crabs, mole crabs, lobsters, true shrimps and the stomatopods or mantis shrimps. There are more than 22,000 taxa in this group representing two third of all crustacean species and contains all the larger forms. *Corresponding author: [email protected] 47 Malacostracans play an important role in aquatic ecosystems and therefore their conservation is important. -

The Catalogue of the Freshwater Crayfish (Crustacea: Decapoda: Astacidae) from Romania Preserved in “Grigore Antipa” National Museum of Natural History of Bucharest
Travaux du Muséum National d’Histoire Naturelle © Décembre Vol. LIII pp. 115–123 «Grigore Antipa» 2010 DOI: 10.2478/v10191-010-0008-5 THE CATALOGUE OF THE FRESHWATER CRAYFISH (CRUSTACEA: DECAPODA: ASTACIDAE) FROM ROMANIA PRESERVED IN “GRIGORE ANTIPA” NATIONAL MUSEUM OF NATURAL HISTORY OF BUCHAREST IORGU PETRESCU, ANA-MARIA PETRESCU Abstract. The largest collection of freshwater crayfish of Romania is preserved in “Grigore Antipa” National Museum of Natural History of Bucharest. The collection consists of 426 specimens of Astacus astacus, A. leptodactylus and Austropotamobius torrentium. Résumé. La plus grande collection d’écrevisses de Roumanie se trouve au Muséum National d’Histoire Naturelle «Grigore Antipa» de Bucarest. Elle comprend 426 exemplaires appartenant à deux genres et trois espèces, Astacus astacus, A. leptodactylus et Austropotamobius torrentium. Key words: Astacidae, Romania, museum collection, catalogue. INTRODUCTION The first paper dealing with the freshwater crayfish of Romania is that of Cosmovici, published in 1901 (Bãcescu, 1967) in which it is about the freshwater crayfish from the surroundings of Iaºi. The second one, much complex, is that of Scriban (1908), who reports Austropotamobius torrentium for the first time, from Racovãþ, Bahna basin (Mehedinþi county). Also Scriban made the first comment on the morphology and distribution of the species Astacus astacus, A. leptodactylus and Austropotamobius torrentium, mentioning their distinctive features. Also, he published the first drawings of these species (cephalothorax). Entz (1912) dedicated a large study to the crayfish of Hungary, where data on the crayfish of Transylvania are included. Probably it is the amplest paper dedicated to the crayfish of the Romanian fauna from the beginning of the last century, with numerous data on the outer morphology, distinctive features between species, with more detailed figures and with the very first morphometric measures, and also with much detailed data on the distribution in Transylvania. -
THE DISTRIBUTION of NATIVE and INTRODUCED SPECIES of CRAYFISH in AUSTRIA MANFRED POCKL (Dr M. Pockl, Department of Limnology, In
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Aquatic Commons 4 MANFRED POCKL THE DISTRIBUTION OF NATIVE AND INTRODUCED SPECIES OF CRAYFISH IN AUSTRIA MANFRED POCKL (Dr M. Pockl, Department of Limnology, Institute of Zoology, University of Vienna, and State Government of Lower Austria, Experts for the Conservation of Nature, Landhausplatz 1, A-3109 St Pölten, Austria.) Introduction Crayfish are the largest invertebrates found in European freshwaters north of the Mediterannean region, where river-crabs (Potamon) also occur. Some crayfish attain body lengths greater than 25 cm and exceed 350 g in weight. These decapod crustaceans are omnivores, feeding on a wide variety of small invertebrates, fish, algae and higher aquatic plants, including some riparian vegetation. They also scavenge on dead and dying plants and animals. However, their quantitative role in the trophic economy of streams and lakes is not well understood, especially in relation to population biomass and potential competition with fish. Like the latter, however, crayfish have long been prized by man as a source of food, and in parts of Europe some species have been exploited commercially for many centuries. The most notable of these is the fishery based on the red-clawed or noble crayfish Astacus astacus, which was decimated by the lethal plague fungus Aphanomyces astaci in the late 19th and early 20th centuries. Importations of relatively large species from North America, which are resistant to the fungus but can act as carriers, has led to concerns for the continued existence and conservation of native European species, several of which are now listed as endangered species. -
Estimating the Population Size of Astacus Leptodactylus (Decapoda: Astacidae) by Mark-Recapture Technique in E₣Irdir Lake, Turkey
African Journal of Biotechnology Vol. 10(55), pp. 11778-11783, 21 September, 2011 Available online at http://www.academicjournals.org/AJB DOI: 10.5897/AJB11.758 ISSN 1684–5315 © 2011 Academic Journals Full Length Research Paper Estimating the population size of Astacus leptodactylus (Decapoda: Astacidae) by mark-recapture technique in Eirdir lake, Turkey Yildiz Bolat1*, Yavuz Mazlum2, Aydin Demirci2 and Habil Uur Koca1 1Departmant of Fishing and Fish Processing Technology, Faculty of Fisheries, University of Süleyman Demirel, 32500 Eirdir, Isparta, Turkey. 2Faculty of Fisheries, Mustafa Kemal University, TR-31200 Iskenderun-Hatay, Turkey. Accepted 13 June, 2011 The mark-recapture technique for closed populations was employed to estimate the population size and density of Astacus leptodactylus during August and September, 2005 by using minnow traps of 34 mm mesh size in Eirdir Lake. A total of 600 minnow traps were set randomly along the shoreline at approximately 3, 5 and 7 m depth. The nets were set in the late afternoon to each study depths, and were hauled the next day or after two days. The research was performed two times each month. In August, 1956 adult crayfish and in September, 2756 adult crayfish were marked by cauterization of the carapace. The recapture rates were found to be 3.5% in August and 2.3% in September, respectively. A total of 200 crayfish were randomly selected, 74 females and 126 males. The sex ratio was 1:1.7. Moreover, length and weight data gotten from 200 untagged crayfish showed that females and males differed significantly in their weight, but no significant difference was evident in the carapace length. -

Especially alarming are recent confirmation of two distantly separated marbled crayfish Procambarus fallax f. virginalis populations in Ukraine and indications of more North American cambarids present in the local pet market. The present study aimed to investigate crayfish species availability within the Ukrainian pet trade together with the climate match and risk they represent to the freshwater ecosystems generally and indigenous crayfish species in particular. Altogether, 15 NICS belonging to all three crayfish families were detected. Considering their origin, availability, probability of establishment, invasiveness and further aspects, marbled crayfish and red swamp crayfish Procambarus clarkii appear to be potentially the most troubling. -
