Biochemical impacts of salinity on the catfish, Heteropneustes fossilis (Bloch, 1794), and possibility of their farming at low saline water

Abstract

Although a stenohaline freshwater fish, the stinging catfish Heteropneustes fossilis, is also available in the freshwater fringes of the coastal areas of Bangladesh, the tolerance of this species to variable environmental salinity has not been thoroughly investigated. This study aims to understand salinity tolerance level by monitoring the growth, survival and biochemical parameters of H. fossilis under different salinity exposure for a period of 90 days.
