Bottom trawl fish composition of Çandarlı Bay (Aegean Sea)
Abstract :
The fish composition of five different stations in Çandarlı Bay (Aegean Sea) were studied by means of seasonal trawl surveys between March 2003 and August 2004. Samplings were carried out onboard R/V Egesuf by employing a conventional bottom trawl commercially used in Turkish waters during daylight hours. A total of 60 fish species of 49 bony and 11 cartilaginous fishes from 33 families were collected in the study area. The species of the group osteichthyes was the highest percentage in terms of number and weight. Mullus barbatus (% 15.63), Citharus linguatula (% 13.36), Diplodus annularis (% 13.27), Serranus hepatus (% 12.28) ve Merluccius merluccius (% 10.89) were determined dominant fish species during the studying period. While catched fishes’s rate of among the whole prey was 89 %, following that cephalopods are 9.52 % and crustaceans are 1.42 %. successively Total 37 fishes species in station III and total 36 fishes species in station II and also total 35 fishes species in station IV were found. According to statistical analyses, species diversity, maximum species richness and Evenness Function were computed as H =2.950, Hmax=4.17 and J =0.715 respectively.
