Age and growth of Nemipterus randalli from Antalya Gulf-Turkey

Abstract

Age, growth, length-length and length-weight relationships were estimated for Nemipterus randalli Russell, 1986 specimens captured between September 2012 and April 2014 from Gulf of Antalya, Turkey. We examined a total of 175 individuals, of which range in size between 6 and 24 cm in total length, 3.4 and 201 g in total weight. Maximum ages were III for female and IV for male. The overall male to female ratio was 0.90/1.0. The length–weight relationship for all individuals were described by the parameters: a = 0.0105 and b = 3.0426. Von Bertalanffy growth equations were estimated as Lt = 33.15[1-e -0.218(t+0.215) ] and Wt=444[1-e -0.218(t+0.215) ] 3.0426 and the phi-prime test estimation was calculated as 2.38 in the population. This study also presents the relationships between total length-standard length, total length-fork length, standard length-fork length, total length-head length, total length- head depth, total length- body depth, total length-otolith length, total length-otolith width, body depth-head depth, head length-head depth and body depth-head length for N. randalli.
