Length-weight and length-length relationships of Aphanius dispar dispar (Rüppell, 1829) in Dalaki river, Bushehr, in south of Iran

Abstract

Length-weight and length-length relationships were derived for Aphanius dispar dispar in Dalaki river (in south of Iran). Sampling was done between January to August of 2011 using scoop net. The b value in the length-weight relationship did not differ significantly between males and females (t-test, P>0.05) and this value was significantly higher than 3 (P 0.05). This study reports the length-weight relationship of A. dispar dispar for the first time in the worldwide and it provides basic information for i¬shery biologists in Iran. Key words: Aphanius dispar dispar, Length-weight relationships, length-length relationship, Dalaki River.
