Histopathological changes in the internal organs of female striped gourami (Trichogaster fasciata) exposed to sub-lethal concentrations of salt water

The present study was conducted to evaluate the effects of climate induced salinity on histoarchitecture of liver, kidney and ovary tissue of female striped gourami (Trichogaster fasciata) exposed tothree sub-lethal concentrations (3, 6 and 9 ppt) of crude salt along with a control group (0 ppt) for a periodof 30 days. The 96-h LC50 value of crude salt for striped gourami was previously estimated as 11.107 ppt. Toconduct the experiment 12 plastic tanks each having 70L water holding capacity were used for the fourtreatments with three replications for each. Water exchange was done on every 10th day and crude salt wasused to maintain desired salinity. Several histopathological changes were observed in fish liver, kidney andovary exposed to different concentrations of…
