Abstract

The invention relates to feed for parent coilia mystus and belongs to the technical field of compound feed for aquatic animals. A formula of the feed for the parent coilia mystus contains the ingredients in percentage by mass: 63% to 65% of fish meal, 9% to 11% of fish oil, 3% of casein, 13% of wheat flour, 2% of maize flour, 2% of egg yolk, 1% of beer yeast, 0.3% of chitin, 0.7% of choline chloride, 0.5% of cuttlefish viscus meal, 1% of calcium dihydrogen phosphate, 1.5% of carboxymethyl cellulose, 0.5% of multivitamins and enzyme mixtures and 0.5% of complex minerals. The formula of the feed provided by the invention is formed on the basis of carrying out comprehensive study on the nutritional requirements of the parent coilia mystus and has extensive experimental foundations and scientific bases; the feed is high in utilization ratio and low in culture water pollution, so that large-scale popularization is facilitated; the feed is used for feeding the parent coilia mystus and is good in palatability, and the growth speed is high, so that the growth speed of the parent coilia mystus can be remarkably increased, and the maturing of sexual glands of the parent coilia mystus is promoted.

Description

A kind of Coilia mystus (Linnaeus). parent fish feedstuff

Technical field

The invention belongs to aquatic animal mixed feed technical field, be specifically related to a kind of Coilia mystus (Linnaeus). parent fish feedstuff。

Background technology

Coilia mystus (Linnaeus). (Coiliamystus) belongs to Osteichthyes, Clupeiformes, section, and long-tailed anchovy belongs to, and has another name called " long tail anchovy "。Being river mouth straddling fish stocks, Coilia mystus (Linnaeus). inhabits shallow sea at ordinary times, and annual spring lays eggs from marine migration to salt-fresh water region, river mouth half, but never gos deep into pure fresh water area。Just hatching prelarva soon is fattened at the deep water place of rivers mouth, returns to marine after growing to certain specification, and next year reaches sexual maturity。Its food is mainly the ovum of Copepods, oppossum shrimp, amphipoda, Concha Ostreae and other Fish。The Coilia mystus (Linnaeus). flesh of fish is containing substantial amounts of protein, fat etc., delicious flavour。

But due to reasons such as sea environment pollution in recent years and artificial overfishings, natural waters catch reduces year by year, substantially can not form natural production, and then the artificial breeding of Coilia mystus (Linnaeus). receives significantly high attention with cultivation in recent years。In the artificial propagation process of Coilia mystus (Linnaeus)., promote that the gonad maturity of parent fish is a key technology, and parent fish feedstuff is the key factor in parent fish accelerating process。Present stage, the domestic blank that still belongs to of exploitation to Coilia mystus (Linnaeus). Nutritional studies and feedstuff, the relevant scientific paper of nothing and patent can be used for reference。At present, the cultivation of Coilia mystus (Linnaeus). parent fish and accelerating are thrown something and fed snapper, turbot feed more, but without special Coilia mystus (Linnaeus). parent fish feedstuff, cause its gonad development maturation of ovum degree slow, smart low, seriously constrain the development of Coilia mystus (Linnaeus). aquaculture。

Summary of the invention

The technical problem to be solved in the present invention is to propose a kind of Coilia mystus (Linnaeus). parent fish feedstuff, can increase the speed of growth of Coilia mystus (Linnaeus). parent fish, promote the gonad development of Coilia mystus (Linnaeus). parent fish, improves essence maturation of ovum degree。

To achieve these goals, the present invention is by the following technical solutions:

A kind of Coilia mystus (Linnaeus). parent fish feedstuff, the raw material composition of described Coilia mystus (Linnaeus). parent fish feedstuff is by mass percentage: fish flour 63-65%, fish oil 9-11%, casein 3%, flour 13%, Semen Maydis powder 2%, egg yolk 2%, beer yeast 1%, chitin 0.3%, choline chloride 0.7%, squid visceral meal 0.5%, dalcium biphosphate 1%, carboxymethyl cellulose 1.5%, compound vitamin and enzymatic mixture 0.5%, composite mineral matter 0.5%。

Described compound vitamin and enzymatic mixture are the mixture formed by following mass percent: 2.5% vitamin A, 2.5% vitamin D, 15% vitamin E, 0.1% vitamin K₃, 10% vitamin C, 1.5% vitamin B₆, 0.5% vitamin B₁₂, 5.5% inositol, 0.02% biotin, 0.4% lipase, 2% papain, surplus is corn starch。

Described composite mineral matter is the mixture formed by following mass percent: 1.5% sodium fluoride, 8% magnesium phosphate, 1% cupric glycinate, 0.15% cobalt methionine, 0.07% potassium iodate, 1% iron chloride, 0.6% manganese chloride, 3% zinc gluconate, and surplus is zeolite powder。

Beneficial effects of the present invention:

Coilia mystus (Linnaeus). parent fish nutritional need is being carried out being formed on systematic study basis by the formula of feedstuff of the present invention, thus has experiment basis and scientific basis widely。

1) feedstuff of the present invention includes shell-fish according to the natural feeding habits of Coilia mystus (Linnaeus)., thus with the addition of chitin in feedstuff, making feed nutrient more comprehensive, being more nearly the natural feeding habits of Coilia mystus (Linnaeus)., thus improve the Coilia mystus (Linnaeus). parent fish utilization rate to feedstuff。The Coilia mystus (Linnaeus). parent fish efficiency of feed utilization that the Coilia mystus (Linnaeus). parent fish fed with Coilia mystus (Linnaeus). parent fish feedstuff of the present invention relatively uses turbot feed to feed improves 12%。

2) feature that the feedstuff foundation Coilia mystus (Linnaeus). parent fish stage of the present invention is higher to lipid and vitamin E demand, with the addition of the fish oil of 9-11% and account for the vitamin E of feedstuff gross mass 0.075%, lipid and content of vitamin E are higher, thus shortening the gonad maturity time of Coilia mystus (Linnaeus). parent fish, and add the genital gland indices of Coilia mystus (Linnaeus). parent fish。Coilia mystus (Linnaeus). parent fish gonad maturity time advance that the Coilia mystus (Linnaeus). parent fish fed with Coilia mystus (Linnaeus). parent fish feedstuff of the present invention relatively uses turbot feed to feed 15 days, genital gland indices is high by 4.8%。

3) forage feed Coilia mystus (Linnaeus). parent fish of the present invention, good palatability, comprehensive nutrition, the growth of Coilia mystus (Linnaeus). parent fish is fast, and in 40 days, rate of body weight gain reaches 15%, survival rate 92%。
