Embodiment 1

[0010] Embodiment 1: A kind of puffed compound feed that makes the parrot fish fattening period blacken and whiten, get imported fish meal 20Kg, shrimp powder 5Kg, soybean meal 15Kg, miscellaneous meal 15Kg, seaweed powder 1Kg, lecithin 1Kg, fish oil 5Kg, flour 10Kg, Commercially available aquatic product whitening agent 0.5Kg, VC phospholipid 0.2Kg.

[0011] The preparation method of the above-mentioned extruded compound feed for fading black and whitening the parrot fish during the fattening period is: firstly, the above-mentioned raw materials are coarsely powdered and ultra-finely pulverized to make 95% of the materials reach more than 60 mesh, and then enter the mixer and mix for 3-5 minutes. , for puffing and granulation, first conduct conditioning to raise the temperature of the conditioner to 90-110°C, the temperature, air pressure, and humidity of the extruder are adjusted according to the buoyancy and sinking of the feed, which have reached the physical requirements o...

Embodiment 2

[0012] Embodiment 2: a kind of puffed compound feed that makes the parrot fish fattening period blacken and whiten, get imported fish meal 30Kg, shrimp meal 10Kg, soybean meal 25Kg, miscellaneous meal 25Kg, seaweed powder 3Kg, lecithin 1Kg, fish oil 5Kg, flour 30Kg, Commercially available aquatic product whitening agent 0.5Kg, VC phospholipid 0.2Kg, trace element 0.1Kg, multivitamin 0.03Kg and mineral 1Kg.

[0013] The preparation method of above-mentioned feed is identical with embodiment 1.

[0014] The invention is convenient to use, has no poisonous effect, can quickly remove sand from parrot fish, and improves economic benefits.

Abstract

An Amphilophus citrinellus puffed compound feed capable of fading black and whitening in the fattening period comprises the following raw materials in parts by weight: imported fish meal 20-30, shrimp powder 5-10, soybean meal 15-25, miscellaneous meal 15-25, algae powder 1-3, lecithin 1, fish oil 5, flour 10-30, a black fading and whitening agent 0.5, and VC phospholipid 0.2. The feed is convenient to use, without any toxic action. According to the physiological characters of Amphilophus citrinellus, the raw materials such as imported fish meal, the high-quality soybean meal and the shrimp powder are used to provide the essential nutrients for quick fattening of juvenile Amphilophus citrinellus, and the black fading and whitening agent is added to help the Amphilophus citrinellus to quickly fade black band, the production period of Amphilophus citrinellus is shortened, and the economic benefit is improved.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture, and particularly relates to an extruded compound feed for fading and whitening parrot fish during the fattening stage and a preparation method thereof. Background technique: [0002] Parrot fish (scientific name: Amphilophus), or parrotfish, is a tropical fish that lives in coral reefs. It is named for its bright colors and mouth shape resembling that of a parrot. With the continuous expansion of the breeding scale of parrot fish, parrot fish has gradually become a popular ornamental fish for people to raise. However, there is also a difficult problem in the development of the parrot fish industry, that is, the juvenile melanization speed of the parrot fish is extremely slow. In the production cycle of the parrot fish, after the hatching of the eggs, the parrot fish does not have any characteristics of the parrot fish, and the fish body has black spots and stripes. After feeding, the appea...
