Ecological factors affecting Length – Weight relationship of Clarias Batrachus and Labeo Rohita

Résumé fourni par la source

The present study provides first-hand information about length – weight relation of two freshwater species, CLARIAS BATRACHUS and LABEO ROHITA from Ghazipur market, Delhi. We collected 20 specimens, 10 specimens each and took length weight for better conservation techniques and proper management for them. A total of 10 specimens of Clarias Batrachus were examined for study, which has ranging from 13 – 17 Inches (TL) and 80 – 400 gm (TW) and took 10 specimens of Labeo Rohita of 10- 15 inches (TL) and 200 – 470 gm (TW) were used for study of LWR’s and conditions factors. Our study exhibited that Clarias Batrachus and Labeo Rohita exhibited negative allometric growth (b < 3) that fish grow faster compared to their weight. The values of correlational coefficient (r2) and condition factor of Clarias batrachus is and 0.1068 and 10.13 of Labeo rohita is 0.387 and 18.20 respectively. This research will be useful for fishery research, stock management, conservation of estimation of fish conditions Ganga River.
