Problems solved by technology

In the shallow sea culture process, due to the vigorous life activities and active enzyme systems in the red fish, many odorous metabolites are produced. In addition, the feed is generally artificial feed such as fish meal or spoiled miscellaneous fish and shrimp, which makes the original Just have the fish body fishy smell of fishy smell to be stronger, and local flavor is greatly reduced, and this kind of fishy smell is not accepted by consumers in general, and has seriously hindered its product development and the sustainable development of industry

Abstract

The invention discloses a compound feed for crimson snappers. The compound feed comprises a fish and shrimp feed, lemons and tea leaves, and the weight ratio of the fish shrimp feed to the lemons and the tea leaves is 100:0.5-1.5:3-5; preferably, the weight ratio of the fish shrimp feed to the lemons and the tea leaves is 100:1:4. A certain number of lemons and tea leaves are added to the compound feed disclosed by the invention on the basis of a conventional feed, so that the activity of lipoxygenase can be effectively inhibited, the generation of aldehydes materials is reduced, and the stink odor of the crimson snappers is largely reduced; because nutritional ingredients in the lemons and the tea leaves generate a certain attractant effect on the crimson snappers, the immunity of the crimson snappers is improved, and the feed coefficients and the survival rate are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and mainly relates to a compound feed for redfish. Background technique [0002] American redfish (Sciaenops ocellatus), referred to as redfish for short, is a high-protein, low-fat marine economic fish with rich nutritional value and good health functions. One of the high-end hot-selling aquatic products in the world. In the shallow sea culture process, due to the vigorous life activities and active enzyme systems in the red fish, many odorous metabolites are produced. In addition, the feed is generally artificial feed such as fish meal or spoiled miscellaneous fish and shrimp, which makes the original Just having fish body fishy smell of fishy smell is stronger, and flavor reduces greatly, and this fishy smell is not accepted by consumers in general, and has seriously hindered its product development and the sustainable development of industry. According to the analysis, the content of al...
