Problems solved by technology

Under artificial conditions, the grouper can be induced to prey on the compound feed by domesticating the grouper, because the nutritional combination of the compound feed is mainly plant-based protein, which cannot meet the daily impact needs of the grouper, so the growth of the grouper is relatively slow; However, fresh bait or minced meat bait itself is difficult to disinfect and carries a large number of bacteria and fungi. Grouper is prone to illness or death after swallowing, which seriously affects economic interests.

Abstract

The invention discloses a compound feed for grouper and a preparation method. The compound feed comprises the following materials in parts by weight: 30-45 parts of fish oil, 15-25 parts of meat powder, 10-18 parts of bone powder, 3-10 parts of shrimp powder, 4-15 parts of chicken intestine powder, 2-10 parts of spirulina powder, 2-10 parts of a phagostimulant and 5-25 parts of a filler. The preparation method comprises the following steps: stirring the materials uniformly, and carrying out granulation by a fluidized-bed spraying technology to obtain the compound feed for the grouper. The compound feed and the preparation method disclosed by the invention have the beneficial effects that the meat powder, the bone powder, the shrimp powder and the chicken intestine powder in a formula of the feed are very-good animal protein baits, so that not only can sufficient animal protein nutrition be provided for the grouper, but also the fragrance is strong, and the effect of inducing the feeding of the fish is achieved; hydrolyzed mussel protein powder has extremely-fragrant shellfish meat flavor, and has great feeding-promoting effect; the anise oil is a natural plant extracting solution, has the fragrance of anise and has good feeding-attraction effect for the grouper; and the spirulina powder has the effects of enhancing the immunocompetence of the grouper and reducing the occurrence of diseases.

Description

technical field [0001] The invention relates to a fish feed, in particular to a grouper compound feed and a preparation method thereof, and belongs to the technical field of breeding feed. Background technique [0002] Grouper (Epine phalus sp.) belongs to the order Perciformes and the family Serranidae. It is a warm-water fish widely distributed in the Indian Ocean and the Pacific Ocean. There are more than 30 species distributed in my country. Grouper meat is plump and tender, rich in nutrition, and is highly praised by people. Live fish is sold in Hong Kong and Macao markets, and is regarded as a first-class delicacy, and the supply exceeds demand; it is expensive and has high economic value; in recent years, with the development of aquaculture industry, The artificial breeding of grouper has attracted more and more attention. Grouper is a typical carnivorous fish with a ferocious nature. It feeds on fish, shrimp and cephalopods. When feeding, it swallows it in one bite....
