Abstract

This study presents a comprehensive analysis of monthly catch data for Labeo rohita (Rohu) collected from the Khambo landing site at Keenjhar Lake over a 12-month period (January to December 2025). A total of 20 boats were sampled monthly from an operational fleet of 250 boats, with fishing activity occurring 9-10 days per month. Catch per unit effort (CPUE) was calculated for both number of fish and weight (kg). The results indicate significant seasonal variation in Rohu catch, with peak abundance observed during the post-monsoon period (September-November). The lowest catches were recorded during the pre-monsoon months (March-April). The highest monthly catch (both in number and weight) occurred in November (920 fish, 659kg), while the lowest was recorded in March (489 fish, 380 kg). The mean weight per fish varied throughout the year (0.484-1.136kg), with larger specimens caught during the pre-monsoon period (February-April) and smaller fish dominating the post-monsoon catch (July-October). Statistical analysis revealed significant seasonal differences in both the number (ANOVA, F=6.23, P<0.01) and weight (ANOVA, F=4.87, P<0.05) of fish caught. These findings provide crucial baseline data for sustainable fisheries management and highlight the need for seasonal fishing regulations, particularly mesh-size restrictions during the post-monsoon recruitment period, to ensure the long-term viability of the Rohu fishery in Keenjhar Lake.
