Özet
This study was conducted to determine the effects of seasonal variation on condition factor (CF) and weight length relationships (WLRs) in Holothuria pardalis collected during January to December 2016. Total (n = 452) sample of H. pardalis were collected during pre monsoon, monsoon and post monsoon season from two rocky shores of Buleji and Sunehri coast of Karachi. The highest mean length 17.1 +/- 0.70 cm and weight 20.3 +/- 0.63 g were recorded in post-monsoon season and minimum length 10.7 +/- 0.59 cm and weight 14.0 +/- 0.72 g were recorded in pre-monsoon season. The results showed that H. pardalis has negative allometric (b < 3) growth characteristics in all seasons (P < 0.05) as it appears to be the general case in other holothurian species. One-way ANOVA test showed that the CF values were statistically difference among three seasons. The mean CF values in Buleji area were estimated statistically higher than in Sunehri in pre-monsoon and monsoon (P < 0.05). But, it was estimated lower in Buleji area than Sunehri area in post-monsoon (P < 0.05).
