Temporal changes in digestive enzyme activities in the gastrointestinal tract of European eel (Anguilla anguilla) ( Linneo 1758 ) following feeding.
Changes occurring after feeding in the digestive enzyme activities of European eel were investigated to provide some insights into the digestive physiology of this fish. Total and specific proteases, amylase and lipase activities were measured using standard biochemical assays over a 24 h cycle in f...
