Abstract:
Lipase activity in stomach and pyloric caeca, liver, intestine and red muscle of rohu (Labeo
rohita Hamilton), oil sardine (Sardinella longiceps Linnaeus), mullet (Liza subviridis Valenciennes) and
Indian mackerel (Rastrelliger kanagurta Cuvier) was studied. Distinct differences in lipolytic activity in
different tissues of these fish were observed. Rohu showed the highest activity in all tissues in comparison
with the other three species of fish. Among the three size groups of mullet, medium-sized mullet showed
higher activity than the other two groups in all tissues except intestine. Rohu hepatopancreatic lipase
exhibited more hydrolytic activity on fish oil than rohu intestinal lipase.
