Compound feed for groupers

Abstract

The invention discloses a compound feed for groupers. The compound feed for the groupers comprises the following raw materials in parts by weight: 50-80 parts of clam worm powder, 20-40 parts of fish meal, 10-20 parts of earthworm meal, 10-20 parts of cod-liver oil, 1-8 parts of a feed attractant and 1-5 parts of an innate immunity enhancer. The fish meal, the clam worm powder, the cod-liver oil and the earthworm meal in the compound feed are good animal protein baits; the sufficient animal protein nutrition can be supplied for groupers; the compound feed is rich in fragrance and has the effect of inducing fishes to take food; a yeast extract and allicin are pure natural feed attractants, are strong in acid smell and have the effects of simulating the appetite of the groupers, promoting the food intake and improving the food taking efficiency of the groupers; spiral seaweed serves as an innate immunity enhancer, naturally has the fishy smell of seaweed and has the effects of promoting the food intake of the groupers, enhancing the autoimmunity capability of the groupers and reducing the occurrence of diseases.

Description

technical field [0001] The invention relates to a fish feed, in particular to a grouper compound feed, which 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. Under artificial breeding cond...

AI Technical Summary

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.
