Description

A kind of loach large size seedling seed is cultivated pond and breeding method
Technical field
The invention belongs to technical field of aquaculture, be specifically related to a kind of loach large size seedling seed and cultivate pond and breeding method.
Background technology
Loach (Misgurnus anguillicaudatus) is under the jurisdiction of net-rope, Cypriniformes, and Cobitidae, loach belongs to.These species are distributed widely in the countries and regions such as China, Japan, Korea, Russia and Southeast Asia, mainly be distributed in the natural water areas such as the river, irrigation canals and ditches, paddy field, pond, lake, reservoir of eastern region in China, having high edibility and medical value, is the important small-sized economic fish of China.
In recent years, loach has become one of best-selling kind in fish market, but due to the increase of catching intensity and the destruction of Natural Water environment, its wild resource amount falls sharply.Uneven the making people worried of quality of loach wild[l on market simultaneously.Owing to fishing for and transportation meeting causes certain injury to loach wild[l, add the seed of lowered in field environment growth and very easily carry germ, in highdensity transportation environment, between seed, infect mutually, cause the wild weed survival rate of loach low.In addition, the loach seed in wild environment often can not obtain sufficient bait, and this makes loach wild[l often in the unbalanced state of nutrition, and then causes its growth rate slow.
Loach wild resource fall sharply and wild[l germplasm measures less than guarantee, make fish market now more and more urgent to the good artificial seed's of loach demand.The artificial propagation of loach is captured already, but the cultivation technology of loach large size seedling seed is not captured so far completely.At present, loach offspring seed cultivation method is comparatively single, and people select pond purse seine method to cultivate loach large size seedling seed conventionally, and the cultivation efficiency of this kind of method is very low, and main manifestations is that weed survival rate is low and seed cultivation density is little.The loach spray that artificial breeding obtains grows into a cun sheet (3cm is long) in pond, and survival rate generally only has 5-10%, and domestic top level also only can reach 30%; The density of the loach seed of pond rearing is not high yet simultaneously, can reach at most 600,000 spray/mus.This is seriously restricting the development of China's loach breeding industry.The 3cm and the above Manual loach that obtain high-quality become the most important guarantee that China's loach breeding industry health develops rapidly.
Summary of the invention
The loach large size seedling seed that the object of this invention is to provide a kind of high cultivation density, high-servival rate is cultivated pond and breeding method.
For realizing the method, first the present invention provides a kind of loach large size seedling seed to cultivate pond, this cultivation pond comprises fountain square and micropore aeration pipe, the top of described fountain square is provided with feed cock, at the bottom of the pond of described fountain square, be provided with the first row water drum of hollow, described first row water drum lower end is communicated with drainpipe through at the bottom of the pond of fountain square, the barrel of described first row water drum is provided with several osculums, described osculum is positioned at top at the bottom of the pond of fountain square, and described micropore aeration pipe is located at surrounding at the bottom of the pond of fountain square.
Described first row water drum is positioned at the centre of fountain square.
At the bottom of the pond of described fountain square, be high, the middle low infundibulate of surrounding, the pond bottom sloping of fountain square is 1-10 degree.
At the bottom of the pond of described fountain square, be also provided with the second row water drum of hollow, the lower end of described second row water drum is communicated with drainpipe through at the bottom of the pond of fountain square.
Described second row water drum is positioned at the Chi Jiao of fountain square.
On this basis, the present invention further provides a kind of breeding method of loach large size seedling seed, the method comprises the following steps:
1) Fertilized Eggs of Loach is invested in to described loach large size seedling seed and cultivates in pond, the control depth of water is 10-50cm, and water temperature is 20-30 ℃, and the dissolved oxygen in water is more than 5mg/L;
2) incubating oosperm two days later, raise 4 days by the halogen worm of first throwing something and feeding, then throw something and feed halogen worm and earthworm mix and raise 3 days, and finally throw something and feed earthworm and special feed are raised to adult, and described special feed is grouped into by the one-tenth of following weight percentage:
Trace element and the mineral matter pre-mixing agent of fish meal 30~60%, dregs of beans 5~20%, wheat flour 5~20%, sodium carboxymethylcellulose 3~6%, starch 5~8%, dextrin 1~6%, soybean lecithin 4~8%, fish oil 1~5%, soybean oil 2~5%, vitamin C 0.02~0.1%, microcrystalline cellulose 2~3% and 2~6%.
Preferably, described trace element and mineral matter pre-mixing agent contain vitamin A, neo dohyfral D3, vitamin E, prokeyvit, vitamin B1, vitamin B2, vitamin B6, cobalamin, vitamin h, inositol, nicotinic acid, general resin acid calcium, folic acid, Choline Chloride, magnesium sulfate, sodium hydrogen phosphate, dipotassium hydrogen phosphate, zinc sulphate, copper sulphate, manganese sulphate, cobalt sulphate, aluminium hydroxide, ironic citrate, calcium lactate, calcium iodate.
The invention has the beneficial effects as follows:
1) depth of water in pond can be controlled in the cultivation pond in the present invention, and can make inflow and water yield under the various depth of water reach balance, thereby for fresh water is provided in pond incessantly, ensure the water quality in pond, can also make water body not arrhea in pond moving simultaneously, thereby for the fish of cultivation provide a kind of fine bourn environment of simulating nature, promote fish growth, improve fish survival rate.Micropore aeration pipe is for water oxygenation, at the bottom of first row water drum in the middle of at the bottom of pond and funnel shaped pond, can make water body in pond, form micro-whirlpool, not only be more suitable for fish growth, rubbish, ight soil etc. at the bottom of pond can also be washed near the first row water drum in the middle of pond, thereby provide good growing environment for the fish at the bottom of pond.The effect of second row water drum is that while avoiding excessive into water, water body covers pond, prevents that the fish in pond from escaping.The present invention is particularly suitable for liking the fish of perch in water bottom, as loach.
2) adopt method of the present invention can realize high density (0.32 ten thousand sprays/m 2, be about 2,100,000 spray/mus) and cultivate loach large size seedling seed (very little sheet), last the cultivation of 20-22d, more than loach can grow to 3cm from spray, per mu yield can reach 1,300,000 tails (0.19 ten thousand/m 2), survival rate reaches more than 60%, is domestic and international top standard.
