Abstract

The present study was conducted to determine the effect of seasonal variation on condition factors (CFs) and weight - length relationships (WLRs) of Tiger Perch, Terapon jarbua (Forsskål, 1775) collected from landing centre at Korangi fish harbour during January to December 2014. A total of 224 specimens were collected during different seasons such as pre-monsoon, monsoon and post-monsoon seasons. The results showed that T. jarbua has negative allometric growth characteristics in pre-monsoon, positive allometric growth in monsoon, and isometric growth character in post-monsoon season (Pauly’ t test, P > 0.05). The values of r are different from zero (P < 0.05), indicated that T. jarbua has higher correlation in WLRs equations. Moreover, to compare the results calculated from the present study with previous studies, log a values were plotted against values of b, which proved to be consistent with previous studies data for T. jarbua. CFs for T. jarbua was estimated to be the highest value in pre-monsoon (mean: 2.6994±0.0649), followed by post-monsoon (mean: 0.7875±0.0139) and monsoon (mean: 0.4903±0.0105) season. One way ANOVA test showed that seasonal significant differences were found in condition factor of T. jarbua at P < 0.05.
