The cover codend method was applied for the sampling. The logistic function for the probability of retention by the codend was used for the estimation of selectivity parameters from all data combined. The results indicated that the 16 mm mesh size was not selective and that almost all individuals were retained. The 24 mm and 26 mm mesh size showed quite similar results and were a little more selective than the 20 mm mesh size. None of the experimental mesh sizes proved to be adequate for N. norvegicus, since all estimated values of length of 50\% retention (L50) were lower than the length at first maturity and those of length of 25\% retention (L25) were lower than the legislated minimum landing size. It is suggested that mesh size should be much larger than 20 mm, the size legislated by E.U. for the Mediterranean.}, keywords = {Crustacea Decapoda, eastern Mediterranean, Greece, Mesh size, Nephrops norvegicus, Norway lobster, selectivity, trawl}, author = {Mytilineou, C. and Chrissi-Yianna Politou and Fourtouni, A.} } @article {15310, title = {The occurrence of Potamon species (Decapoda, Brachyura) relative to lotic stream factors in Greece}, journal = {Biologia - Section ZoologyBiologia - Section Zoology}, volume = {59}, number = {2}, year = {2004}, note = {Export Date: 5 September 2006Source: ScopusReferences: Public participates in survey on aquatic organisms (2000) Japan Environmental Quarterly, 5 (3). , http://www.env.go.jp/en/org/jeq/v005-03.html; Bechev, D.N., New localities of Potamon fluviatilis (Herbst, 1785) (Crustacea: Decapoda) in Bulgaria (2000) Trav.

Recently, however, it has been recorded from a variety of depths inside the Aggitis Cave in northern Greece. The crayfish have been found in the out flowing River Aggitis, in the entrance to the cave, as well as at 2,100 m and 7,100 m from the entrance. The crayfish found were pigmented in general, although those from the deeper parts had characteristically bluish pereopods. The finding of crayfish so deep inside a cave system is unusual, and is probably the deepest record so far in Europe and North America. The origin of the deep-dwelling crayfish is unknown. Although they occur above the cave system, it is unlikely that they could have entered the system from there in recent times due to a build up of sediment, but they may have become trapped in the cave prior to this happening. Alternatively, they may have moved upstream into the cave system over time. It is hoped to determine whether they complete the whole of their life history in the cave system and what they are feeding on.}, keywords = {Aggitis Cave, Austropotamobius torrentium, Cave dwelling species, Crayfish, Greece, KAPE crustacea decapoda}, author = {Koutrakis, E.T. and Machino, Y. and Kallianiotis, A. and Holdich, D.M.} }
