Abstract

The scope for growth as a proportion of the energy absorbed and is а measure of the efficiency with which the food is converted into body tissues. It is mentioned in both net and gross growth efficiency. In this study, the scope for growth and growth efficiency of the bivalve Azumapecten ruschenbergerii have been investigated at Chabahar Bay before and after summer monsoon, as a laboratory experiment. Monsoonal climate dominates the northern Indian Ocean, and its effects felt in summer and winter with stronger winds in summer. According to this, the study on the energy budget of mentioned bivalve at 19 to 33 °C showed that the average of both indices has significant increase after summer monsoon (P<0.001). The results indicated that A. ruschenbergerii is opposed to better condition and less stress after the monsoon.
