Artificial Diets for Common Carp: Effect of the Addition of Enzyme Extracts

Abstract

An experiment on feeding the larvae of carp (Cyprinus carpio) with an artificial diet is described, and 3 previous years of study are briefly summarized. When extracts offish digestive enzymes from hepatopancreas and intestine were added to the diet processed by freeze-drying, growth and survival of the larvae were better than in our previous experiments, but not as good as when the larvae were fed natural food. After 16 days, an increase of 7-10 mg in individual body weight offish was observed and survival was 22-44%.
