Özet
In this study, fecundity, egg size and development of Plesionika martia, Plesionika heterocarpus (Caridae), Chlorotocus crassicornis (Pandalidae), Munida rutllanti (Galatheidae) were studied. The Samples of Decapod crustaceans were collected by commercial trawler "Hapuloglu" between the depths of 240 m and 460 m from the international waters of middle Aegean Sea. Carapace length-weight relationship were found W=0.4945 x CL-3.9564, W=0.3681 x CL-2.8551, W=0.1963 x CL-1.3166, W=0.3904 x CL-3.0074 for P. martia, P. heterocarpus, C. crassicornis, M. rutllanti respectively. The mean brood size was calculated as 11671 (S.D. +/- 752) for P. martia. Average number of eggs was estimated as 2895 (S.D. +/- 1386) for M. rutllanti, 2925 (S.D. +/- 721) for P. heterocarpus and 2056 (S.D. +/- 533) for C. crassicornis. Relationship between number of eggs and carapace length of species were determined by the following equations as F = 730.38 x CL - 579.40 for P. martia, F = 374.99 x CL - 2277.7 for P. heterocarpus, F = 194.20 x CL - 1080.80 for C. crassicornis, F = 689.47 x CL - 5895.60 for M. rutllanti.
