Epinephelus akaara compound feed and preparation method thereof

Abstract

The invention relates to a compound feed for aquaculture animals, particularly relates to an epinephelus akaara compound feed, and further relates to a preparation method for the epinephelus akaara compound feed. The epinephelus akaara compound feed disclosed by the invention is composed of the following various components in parts by mass: 20-30 parts of fish meal, 10-18 parts of euphausia superba meal, 10-18 parts of clam worm meal, 6-10 parts of kelp meal, 6-10 parts of red bean meal, 4-8 parts of cottonseed meal, 4-8 parts of sweet potato meal, 4-8 parts of rapeseeds, 4-6 parts of lucerne meal, 2-4 parts of houttuynia cordata, 1-3 parts of dandelion, 1-3 parts of dry ginger powder, 1-2 parts of shell powder, 1-2 parts of compound multivitamins, 2-4 parts of fish oil and 1-3 parts of soybean oil. The epinephelus akaara compound feed disclosed by the invention has the advantages of being low in feed coefficient, high in specific growth rate of bastard halibut after feeding bastard halibut, and high in survival rate.

Description

Technical field [0001] The invention relates to a compound feed for aquaculture animals, in particular to a compound feed for Epinephelus grouper; the invention also relates to a method for preparing the above-mentioned Epinephelus grouper compound feed. Background technique [0002] Epinephelus akaara (Epinephelus akaara) is commonly known as grouper and erythema. It is one of the species of Perciformes Serranidae in the class Perciformes. It is distributed in subtropical and tropical seas all over the world. Its meat is plump and tender. Rich in nutrients, it is an important marine aquaculture fish and one of the most important marine cage culture high-end fish in China. The cultivation of Epinephelus grouper is mainly concentrated in Asia. The cultivation of Epinephelus grouper abroad began in the 1960s and the domestic one began in the 1970s. It is mainly concentrated in coastal Fujian, Guangdong, Zhejiang, Hainan, Guangxi and Taiwan. And other provinces. At present, the cu...

Problems solved by technology

Under artificial conditions, the grouper can be induced to prey on the compound feed by domesticating the grouper. However, since the nutritional combination of the compound feed is mainly plant-based protein, it cannot meet the daily impact needs of the grouper, and the red-spotted grouper does not like it. Ingestion, so the feed efficiency is low, and the growth of red-spotted grouper is relatively slow after feeding; and fresh bait or minced meat bait carries a large amount of bacteria and fungi due to its own difficulty in disinfection, and the grouper is prone to illness or death after swallowing. thereby seriously affecting the economic interests of

With the vigorous development of the red-spotted grouper aquaculture industry, it is urgent to provide high-quality compound feeds that can meet its growth and nutritional needs. High-quality compound feed that can meet the growth and nutritional needs of red-spotted grouper, has a low feed factor, and has a high specific growth rate after feeding red-spotted grouper
