LENGTH-WEIGHT RELATIONSHIPS FOR 30 DEMERSAL FISH SPECIES FROM �ANDARLI BAY (NORTH AEGEAN SEA, TURKEY)

Abstract

Length-weight relationships were investigated for 30 demersal fish species from Çandarlı Bay in the North Aegean Sea. Fish samples were caught from depths of 30-95 m in five different stations by bottom trawl between March 2003 and August 2004. The b values in the length-weight relationship varied between 1.654 and 3.977, over 50% of which between 2.968 and 3.265 with a mean value of 2.949 (SE = ±0.05). The growth type was determined by t-test: 13 species (43%) showed positive allometries (b > 3; t-test, P < 0.05), 13 species (43%) isometric growth (b=3; t-test, P > 0.05) and the remaning 4 species (14%) negative allometries (b<3; t-test, P < 0.05).
