Embodiment 1

[0054]

[0055]Prepare powdered feed according to the formula shown in the above table, and use it to feed the flower eel in the fish-growing stage. The crude protein content of the feed is ≥ 40%. The oligopeptide-rich flower eel compound feed of this embodiment is used for the adult fish stage of other flower eels. Feed, low cost, good food attractant, good viscoelasticity, fast growth of flower eel, good breeding effect and good economic benefits.

Embodiment 2

[0057]

[0058] Formulate powdered feed according to the formula shown in the above table, which is suitable for feeding the flower eels in the juvenile stage. Since the nutritional requirements of the juvenile stage are higher than that of adult fish, the proportion of fish meal should be appropriately increased, and the crude protein content of the feed should be ≥ 45%. This example is adopted Compared with other compound feeds for juvenile eels, the oligopeptide-rich compound feed for flower eels has low cost, good food attractant, good stability in water, fast growth of flower eels, good breeding effect, and good economic benefits.

Embodiment 3

[0060]

[0061] Formulate powdered feed according to the formula shown in the table above, which is suitable for feeding flower eels in the black baby stage. The black eel stage not only has high nutritional requirements, but also has higher requirements for viscoelasticity, so the amount of fishmeal is increased to 45%, and the crude protein content of feed is ≥47%. The oligopeptide-rich compound feed for flower eel of this embodiment is lower in cost, better in attracting food, better in water stability, faster in growth of flower eel, better in breeding effect, and good in economic benefits than other compound feeds for black baby of flower eel.

Abstract

The invention discloses an oligopeptide-rich powder-type compound feed for anguilla marmorata. The compound feed comprises the following raw material components: fish meal, alpha-starch, extruded soybeans, oligopeptide bean pulp, beer yeast, mineral substances, multivitamins for fish, choline chloride, monocalcium phosphate and the like. According to the compound feed disclosed by the invention, different artificial compound feeds are scientifically prepared from the raw materials according to physiological characteristics of the anguilla marmorata. Compared with other feeds, the compound feed has the advantages that the contents of oligopeptide and plant protein are remarkably increased, and the use level of the fish meal is obviously reduced; by adding oligopeptide protein, the immunity of fishes can be enhanced, the synthesis of the internal proteins is accelerated, and the growth of the anguilla marmorata is promoted; by adding the plant protein, the culturing cost can be lowered, and meanwhile, nourishments of the feed are comprehensive. With the adoption of the oligopeptide-rich powder-type compound feed for the anguilla marmorata, the nutrition state of the cultured anguilla marmorata can be greatly improved, the digestive absorption of the feed is promoted, the immunity of the anguilla marmorata is enhanced, and the compound feed has an obvious economic benefit.

Description

technical field [0001] The invention relates to the field of aquatic product compound feed, in particular to the field of powdered compound feed for eel. Background technique [0002] Flower eel ( Anguilla marmorata ) belongs to the family Eelidae of the order Eelidae, with delicious meat and high nutritional value, known as "ginseng in water", and is a precious species in fish resources in my country. The market price of flower eel is 3 to 6 times that of other edible eels, and it has extremely high economic value. In recent years, due to serious pollution of natural water bodies and overfishing, wild eel resources have declined sharply. In 1988, it was listed as a second-class national wild animal protection in my country. At present, due to the lack of seedling resources of Japanese eel and European eel, and the rich resources of seedlings of eel in Southeast Asia, especially the northern part of the Philippines, the price of seedlings is cheap.
