Abstract

The relationship between otolith morphology and fish size of Nemipterus japonicus was investigated. Samples of 117 specimen were taken from Iraqi marine waters of Persian Gulf. The outline of the otolith was used to describe its length cm height cm and weight g. Measurements of left and right otolith did not appear significant differentiation, according to T-test. The optimal regression model, which relates otolith weight to the total length and body weight, was found by correlating each otolith parameter to the total length and weight of fishes. There was also a relative positive relationship between dimensions of otolith with the total length and weight of fishes.
