  The activity of the digestive enzymes lipase, α-amylase and disaccharidases (sucrase, maltase, isomaltase and trehalase) was studied in slow-growing and fast-growing groups of farmed Eurasian perch (Percafluviatilis) of different ages.The activity of carbohydrases (disaccharidases and α-amylase), lipase, trypsin and chymotrypsin were also compared in Eurasian perch andArcticcharr (Salvelinusalpinus).No effect was noted of growth rate and age on the digestive enzyme activities in Eurasian perch.Total lipase activity was higher than total combined carbohydrase activity in both species (142.0 vs. 6.2 and 111.0 vs. 2.5 Umg-1 protein for Eurasian perch and Arctic charr respectively; P<0.001 for both). Compared with Arctic charr, Eurasian perch had higher lipase activity in the pancreasand lower lipase activity in the pyloric caeca and mid-intestine. Total chymotrypsin activi.. View More»
