Opis

Longwiskered Catfish (Sperata aor) is undeniably most valuable and delicious fish species in Bangladesh. If artificial breeding and culture of S. aor are not taken immediately, it may be faced in the critical endanger or extinct condition within very few years. S. aor fed on both phytoplankton and zooplankton but showed highest preference for zooplankton. The highest value of VSI (%) was observed at February 5.86 and lowest was observed at July 2.51. The maximum value of HIS (%) was observed at February 1.83 and minimum value was observed in July 1.10. On the other hand, high central infiltrations, less vacuoles, high central vain, less hemorrhages, less necrosis and more visible hepatocytes were observed from April to June and October to December. From January to March less central infiltrations and more vacuoles were found and hepatocytes are not visible. On the basis of macroscopic, microscopic, biometrical and histological parameters, the seasonal histological changes of liver and intestine tissue are related to food and feeding habit of S. aor. It would show some way forward to future research work, and give some guidance and implictions to the practitioners and farm woners.
