Description

A kind of loach large size seedling seed cultivates 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 (Misgurnusanguillicaudatus) is under the jurisdiction of net-rope, Cypriniformes, Cobitidae, and loach belongs to.These species are distributed widely in the countries and regions such as China, Japan, Korea, Russia and Southeast Asia, the natural water area such as river, irrigation canals and ditches, paddy field, pond, lake, reservoir of eastern region is mainly distributed 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.The quality of the loach wild[l simultaneously on market is uneven to make people worried.Owing to fish for and transport can cause certain injury to loach wild[l, the seed of adding lowered in field environment growth very easily carries germ, in highdensity transportation environment, infects mutually between seed, causes the wild weed survival rate of loach low.In addition, the loach fry in wild environment often can not obtain sufficient bait, and this makes loach wild[l often be in the unbalanced state of nutrition, and then causes its growth rate slow.
Loach wild resource fall sharply and wild fry quality can not get ensure, make the demand of fish market now to the excellent artificial seed of loach more and more urgent.The artificial propagation of loach is captured already, but the Cultivating techniques of loach large size seedling seed is not captured so far completely.At present, loach fry breeding method is comparatively single, and people select pond purse seine method to cultivate loach large size seedling seed usually, 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 water flower 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 fry of pond rearing is not high yet simultaneously, can reach 600,000 sprays/mu at most.This seriously governs the development of China's loach breeding industry.The 3cm and the above Manual loach that obtain high-quality become the healthy most important guarantee developed rapidly of China's loach breeding industry.
Summary of the invention
The object of this invention is to provide a kind of high cultivation density, the loach large size seedling seed of high-servival rate cultivates pond and breeding method.
For realizing the method, the present invention provide firstly a kind of loach large size seedling seed and cultivates pond, this cultivation pond comprises fountain square and micropore aeration pipe, the top of described fountain square is provided with feed cock, the first row water drum of hollow is provided with at the bottom of the pond of described fountain square, 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 above 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.
Be high, the middle low infundibulate of surrounding at the bottom of the pond of described fountain square, the pond bottom sloping of fountain square is 1-10 degree.
Also be provided with the second row water drum of hollow at the bottom of the pond of described fountain square, 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 described loach large size seedling seed to cultivate in pond, control water depth is 10-50cm, and water temperature is 20-30 DEG C, and the dissolved oxygen in water is more than 5mg/L;
2) incubating oosperm is two days later, and halogen worm of first throwing something and feeding raises 4 days, then throw something and feed halogen worm and earthworm mixing raising 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:
The trace element 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% and mineral matter pre-mixing agent.
Preferably, described trace element and mineral matter pre-mixing agent contain vitamin A, vitamine D3, vitamin E, Vitamin K3, 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) the cultivation pond in the present invention can control the depth of water in pond, and the inflow under the various depth of water and water yield can be made to reach balance, thus for providing fresh water incessantly in pond, ensure the water quality in pond, water body can also be made not arrhea in pond dynamic simultaneously, thus provide a kind of fine bourn environment of simulating nature for the fish of cultivation, promote fish growth, improve fish survival rate.Micropore aeration pipe is used for water oxygenation, can make water body in pond, form micro-whirlpool at the bottom of first row water drum in the middle of at the bottom of pond and funnel shaped pond, not only be more suitable for fish growth, rubbish at the bottom of pond, ight soil etc. can also be washed near the first row water drum in the middle of pond, thus provide good growing environment for the fish at the bottom of pond.The effect of second row water drum is that when avoiding excessive into water, water body covers pond, prevents the fish in pond from escaping.The present invention is particularly suitable for liking the fish of perch in water bottom, as loach.
2) method of the present invention is adopted can to realize high density (0.32 ten thousand sprays/m 2, be about 2,100,000 sprays/mu) and cultivate loach large size seedling seed (very little sheet), last the cultivation of 20-22d, loach can grow to more than 3cm from spray, and per mu yield can reach 1,300,000 tail (0.19 ten thousand/m 2), survival rate, to more than 60%, is domestic and international top standard.
