Digestive Enzyme Activity in Eurasian Perch (Perca Fluviatilis) and Arctic
Författare: Markus Langeland, Jan Erik Lindberg and Torbjörn Lundh
Utdrag ur publikationen:
"In this study, the objective was to compare digestive enzyme activities in slow and fast-growing groups of Eurasian perch of different ages to evaluate if differences in growth rate could be related to digestive enzyme activity. Furthermore, differences in digestive enzyme activity in Eurasian perch and Arctic charr were studied. The starting hypotheses were that fast-growing perch have higher digestive enzyme activity than slow-growing perch and that there are differences in digestive enzyme activity along the GI tract in Eurasian perch and in Arctic charr."
"The data presented suggests that feed formulation should be different for Eurasian perch and Arctic charr in order to match their inherent digestive enzyme activities. This applies in particular to the carbohydrate content and composition of the feed. Based on the recorded α-amylase and carbohydrase activities,
the carbohydrate content, in particular starch, can be higher in feed for Eurasian perch than in feed for Arctic charr."
