Özet

This study was carried out through monthly deep trawls applications in the waters of 20-100 m of depths in the Gulf of Antalya, between June 2013 and November 2014. The species composition, size frequency distribution and length/weight relationships for each sex of the commercially important shrimp, Penaeus japonicus in the Gulf of Antalya, in Mediterranean Sea were studied. A total of 108 individuals of lessepsian penaeid shrimp were sampled during the study. Length and weight of the samples varied between 10.6-20.3 (12.3 +/- 2.2) mm total length and 11.33-80.17 (29.17 +/- 13.05) g respectively. The smallest individual was sampled in February and the biggest was in April. A total of 63 (% 58) samples were female and 45 (% 42) were male. The relation between total length (CL) and weight (W) was determined as W = 0.0038CL(3,1916) R-2 = 0.9437. This was calculated for females as W = 0.0036CL(3,2158) R-2 = 0.953 and for males W = 0.0121CL(2,7561) R-2 = 0.8582. It was determined that total and females showed positive allometric growth and males were showed negative allometric growth.
