Seasonal changes in condition factor and weight-length relationship of tiger perch, Terapon jarbua (Forsskål, 1775) (Family-Terapontidae) collected from Korangi Fish Harbour, Karachi, Pakistan

The present study was conducted to determine the effect of seasonalvariation on condition factors (CFs) and weight - length relationships (WLRs) of TigerPerch, Terapon jarbua (Forsskål, 1775) collected from landing centre at Korangi fishharbour during January to December 2014. A total of 224 specimens were collectedduring different seasons such as pre-monsoon, monsoon and post-monsoon seasons. Theresults showed that T. jarbua has negative allometric growth characteristics in premonsoon,positive allometric growth in monsoon, and isometric growth character in postmonsoonseason (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, tocompare the results calculated from the present study with previous studies, log a valueswere plotted against values of b, which proved to be consistent with previous studies datafor 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 significantdifferences were found in condition factor of T. jarbua at P < 0.05.
