Trachinotus ovatus overwintering feed, preparation and of overwintering feed and breeding method of trachinotus ovatus

Abstract

The invention provides a trachinotus ovatus overwintering feed, a preparation and of the overwintering feed and a breeding method of the trachinotus ovatus. The overwintering feed comprises the components in parts by weight of 16-20 parts of fish meal, 30-40 parts of compound fermented protein powder, 6-12 parts of corn protein powder, 3-8 parts of shrimp base powder, 4-6 parts of corn oil, 2-4 parts of soybean phospholipid, 2-5 parts of carboxymethyl cellulose, 0.5-1 part of sodium dihydrogen phosphate, 0.2-0.5 part of choline chloride, 0.5-1 part of betaine, 1-2 parts of wild jujube powder,0.05-0.2 part of wormkalk extract, 0.05 to 0.15 part of curcumin, 0.5 to 0.8 part of compound vitamin premix, 0.3 to 0.6 part of compound mineral substance and 0.2 to 0.8 part of compound enzyme preparation. The overwintering feed is more suitable for autumn and winter culture of trachinotus ovatus, and the overwintering capacity of the trachinotus ovatus can be enhanced by combining a reasonableand effective culture method, so that the growth quality and the survival rate of the trachinotus ovatus cultured in winter are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a golden pomfret overwintering feed and a preparation and breeding method thereof. Background technique [0002] The scientific name of golden pomfret is oval pomfret. It is one of the rare and high-grade edible seawater fish. However, since golden pomfret is a warm-water pelagic fish, it is usually advisable to raise it above 23°C. Therefore, in the process of large-scale cage culture, it is often easily affected by low temperature climate, and its ability to survive the winter is low. , less food intake, leading to problems such as slow growth of fish, low immunity, and decreased survival rate. After overwintering, the fish body is thin, and it is difficult to meet the economical and efficient breeding of large-scale golden pomfret in winter. Therefore, a kind of overwintering feed suitable for golden pomfret farming in autumn and winter and its corresponding more reasonab...
