BOAL (WALLAGO ATTU) FISH ABANDONMENT IN KELEGHAI RIVER, WEST BENGAL: AN IDEA BASED CLARIFICATION

Aquatic freshwater fish diversity immensely declines from several native places in West Bengal. Lots of freshwater fish have been extricated and some become endangered or vulnerable in condition as well as in Keleghai river. Aquatic ecosystem meltdown or crisis due to anthropogenic intervention resu...
