Abstract
The invention discloses a fish fry culturing method for four major Chinese carps. According to the fish fry culturing method disclosed by the invention, before culturing, a pond is sprayed by using activated strain liquid, so that pathogenic microorganisms and harmful substances can be killed or inhibited, an cultural ecological environment is adjusted, the amount of dissolved oxygen in water is increased, the activation and growth of normal flora and beneficial algae in a cultural ecosystem are promoted, and the ecological balance of culture water is then kept; activated strain liquid fermented feed is used for feeding, so that the absorption function and disease prevention resilience of fish fries are directly enhanced, and the healthy and robust growth is promoted; phosphorus and calcium in calcium hydrogen phosphate are activation activating elements for enzymes and microorganisms, so that a fermentation process can be promoted; a classified fermentation manner is adopted during fermentation, so that the fermentation effect is enhanced; and several Chinese herbal medicine ingredients are further added during the fermentation, so that the disease resistance of the fish fries is further enhanced, and the survival rate is increased.
Description
Technical field
The present invention relates generally to a kind of four large Chinese carp fry cultural methods, belongs to cultivation field.
Background technology
Along with the expansion gradually of fish culture scale, the problem not running into before many appears gradually, many raisers are high with fish meal protein content, easily cause fatty liver to occur, reduce survival rate and the growth rate of fish, in the process of cultivation not, do not note the variation of water body, it is also recurrent causing the phenomenon such as mortality of fish.Therefore scientific, the standardization of cultivation, rationalize and be only basic that cultivation will pursue.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, and a kind of method of fry cultivation is provided.
The present invention is achieved by the following technical solutions:
A kind of four large Chinese carp fry cultural methods, comprise the following steps:
(1) 3-10 days before putting in a suitable place to breed, with the admixture activation bacterium liquid water surface of splashing, depending on water quality situation, when beginning 13-15 days 1 time is 28-30 days 1 time later, the place that water quality is poor, suitably shorten and splash the time, the amount of sprinkling is: 1-2 kilogram of admixture activation bacterium liquid sprays 1-2 mu;
(2) seedling is put into and cultivate pond, make in water body more than dissolved oxygen reaches every liter of 5-7 milligram by the oxygenation of micro-pore oxygenation machine;
(3) fry goes out after shell, has a lot of egg membranes to stay in water, with gauze along the water surface gently draw volume, the egg membrane of the water surface and dirty foam are adsorbed on gauze, to remove egg membrane;
(4) after the yolk sac of fry disappears, then start the yolk of throwing something and feeding.Method is with the gauze of 1-2 layer, yolk to be encased, crowded broken, then on the water surface, pats, and move on bat limit, limit, and yolk is evenly suspended in water, and throw something and feed 2-3 every day;
(5) after 3-5 day, when the swimming of fry energy level, now can throw something and feed and contain protozoic feed, described feed is made up of the raw material of following weight parts: fairy shrimp 15-20, sandworm 12-15, wheat bran 2-3, rice bran 1-2, dusty yeast 1-2, fly maggot powder 8-10, spirulina 2-3, sugarcane top 13-15, corn flour 3-5, peanut seedling 4-6, stalk 5-8, digua fig stem and leaf 3-5, dregs of beans 12-18, chicken manure 20-25, vinasse 3-6, manioc waste 5-7, Poria cocos 0.8-1, bark of eucommia 0.3-0.5, cordate houttuynia 0.6-0.8;
The fairy shrimp of above-mentioned weight portion, sandworm, fly maggot powder, dregs of beans, sugarcane top are mixed, add water, make its water content reach 45-50%, add the admixture activation bacterium liquid of 0.8-1% and the calcium monohydrogen phosphate of 0.2-0.4%, sealing and fermenting 3-7 days;
The wheat bran of above-mentioned weight portion, rice bran, dusty yeast, spirulina, corn flour, peanut seedling, stalk, digua fig stem and leaf, chicken manure, vinasse, manioc waste, Poria cocos, the bark of eucommia, cordate houttuynia are mixed, add water, make its water content reach 50-60%, add the admixture activation bacterium liquid of 0.5-0.8%, the hydrolyzed casein of 0.01-0.02%, the urea of 0.01-0.02 sodium bicarbonate, 0.01-0.02%, the calcium monohydrogen phosphate of 0.02-0.04%, sealing and fermenting 6-8 days;
Above-mentioned two kinds of tunnings are mixed, after being dried, grinding into superfines and feed;
The preparation method of described admixture activation bacterium liquid is: the lactobacillus acidophilus that is 3-4:3-4:1-2:3-4:1-2 by weight ratio, bacillus subtilis, bafillus natto, Bifidobacterium, streptococcus fecalis preparation mix, mix according to the ratio of weight ratio 1:40-60 with 30-35 ℃ of warm water, be stirred to and be dissolved in completely after water, activating and within 20-40 minute, obtain described admixture activation bacterium liquid, is hundred million/gram of 20-30 containing total viable count.
(5), during seedling culture, carried out a blowdown every 10-12 hour.
Advantage of the present invention is:
The method of cultivation fry of the present invention, before cultivation, spray pond with activation bacterium liquid, can kill or suppress pathogenic microorganism and harmful substance, adjust breeding ecological environment, increase dissolved oxygen in water, promote normal flora and useful algae activation growth in breeding ecological system, keep the ecological balance of breeding water body; Throw something and feed with activating bacterium liquid fermented forage, directly strengthen absorption function and the diseases prevention anti-adversity ability of fish, promote healthy and strong growth, wherein the P elements in calcium monohydrogen phosphate and calcium constituent are the activation active elements of enzyme and microorganism, can promote fermentation process, adopt the mode of classification fermentation in fermentation, strengthen the effect of fermentation, also add during the fermentation several medicinal herb componentses, further strengthened the resistance against diseases of fry, improved survival rate.
