| Abstract | ||
| This study evaluated the length-weight relationship (LWR) and Fulton's condition factor of five small indigenous fish species (n=623); namely, Puntius sophore, Trichogaster fasciata, Lepidocephalichthys guntea, Amblypharyngodon mola and Chanda nama captured during 2018 to 2019 from 10 freshwater bodies of West Bengal, India. For establishing LWR according to seasonal variations, fish were grouped according to the season. The result showed that growth coefficient values varied between 3.875 and 2.337, and the condition factor values ranged between 2.12 and 0.67, which can be due to different environmental conditions. The length-weight relationships were highly correlated in all studied species throughout the seasons. The average condition factor values reflected the good condition of fish in the studied ponds. This study provided baseline data on the length-weight relationship and condition factor of the selected species, which can be used to assess grow-out stocks in a similar environment. | ||
