Abstract:
Present study is the information on Length-weight relationship (LWR), Sex Ratio and Relative Condition Factor (Kn) of the species Thryssa mystax (Bloch & Schneider, 1801)1 belongs to Order: Clupeiformes, Family: Engraulidae recorded from Maharashtra coast, India for the period January 2020 to December 2022. A total of 2814 specimens of T. mystax collected twice in a week, from the catches of gill nets, trawl nets and mini purse seine nets were used for the analysis. Overall length ranged from 10.0 cm - 24.5 cm and weight 12.0 gm - 116.0 gm. The regression values derived for females were r2=0.9596, males r2=0.9566 and pooled specimens r2=0.9667. Growth type for females, males and pooled specimens was isometric. The Sex Ratio, Chi—square derived for all the specimens was 1.05. The p-value observed was more than 0.05 (p=>0.05). The mean relative condition factor values taken in to account, where, the highest mean Kn value for the females was 1.01268 (September) and for the males 1.00534 (November). The length-wise mean relative condition factor was 1.04345 in the specimens at length range 10 - 13 cm (minimum length) and 0.96872 for the maximum length group 23-26 cm, which revealed that, species is relatively in good condition.
