Abstract
The invention discloses a culture method of river prawns. The culture method comprises the following steps of (1) selecting a culture pond, (2) sterilizing the culture pond, (3) preparing before the culture, (4) culturing the prawn seeds. Through the culture method, the immunity and resistance of the river prawn can be improved, the growth speed of the river prawns can be accelerated, the survival rate of the river prawns can be increased, the quality of the river prawns can be guaranteed, the meat of the cultured river prawns is tender and nuisanceless, and the safety quality of the food can be further improved.
Description
Technical field
The present invention relates to a kind of cultural method of aquatic products, particularly the cultural method of a kind of river prawn.
Background technology
River prawn is Fresh & Tender in Texture, delicious flavour, nutritious, it is the aquatic food of high protein and low fat, liked by people, simultaneously along with present growth in the living standard, people are also more and more stronger for the pursuit of gourmet food, on market, the demand of river prawn is more and more, therefore propagating river prawn artificially becomes a kind of imperative trend, but in prior art, the cultural method of river prawn is limited, cause the growth rate of river prawn slower, second-rate.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the cultural method of a kind of river prawn, can strengthen autoimmunity and the resistance of river prawn, accelerate the growth rate of river prawn, improve the survival rate of river prawn, and can ensure the quality of river prawn, Fresh & Tender in Texture, nuisanceless, further improve food security quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the cultural method of a kind of river prawn is provided, and its concrete grammar is as follows:
(1), the selection of culturing pool: selecting area is 3-4 mu, and the pond of depth of water 1.2-1.8m is as culturing pool, and water inlet and the delivery port in described pond are provided with screen pack, and at the bottom of pond, the mud degree of depth is no more than 15mm;
(2), the sterilization of culturing pool: disseminate the disinfection of 300-400 kilogram of raw lime in 1 circumferential pond, then the water in pond is once changed, each water yield of changing is 50% of pool inner water amount;
(3), before cultivation, prepare: in culturing pool, be placed with aerating machine, every 2-3 days, water carried out to oxygenation once, and plant pasture and water at the bottom of pond, described pasture and water comprise: one or more of hydrilla verticillata, marine alga and pondweed, purify water.
(4), the cultivation of shrimp seedling: select shrimp seedling more than 1.5mm specification to throw in, throwing in density is 10000 tail/mus, in 1-15 days that throw in shrimp seedling, the fish meal of throwing something and feeding, throw something and feed 2-3 every day, each feeding volume is the 4-6% of shrimp seedling weight, in 15-30 days that throw in shrimp seedling, and the soya-bean cake of throwing something and feeding, throw something and feed 3-4 every day, each feeding volume is the 6-8% of shrimp seedling weight, behind 30 days of input shrimp seedling, and throw something and feed tiny trash fish or meat mincing, throw something and feed 5-6 every day, each feeding volume is the 10-12% of shrimp seedling weight, until shrimp seedling cuts one's eye-teeth, then is dragged for and catches listing.
In a preferred embodiment of the present invention, the time of throwing in shrimp seedling is annual April or May.
In a preferred embodiment of the present invention, drag for while catching ripe river prawn, adopt cage or fish pot to fish for, and in pond, be sprinkled into benzalkonium bromide in every night.
Beneficial effect of the present invention: the present invention can strengthen autoimmunity and the resistance of river prawn, accelerates the growth rate of river prawn, improves the survival rate of river prawn, and can ensure the quality of river prawn, Fresh & Tender in Texture, nuisanceless, further improves food security quality.
embodiment
The present invention will be described in detail below, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
In an embodiment of the present invention, the cultural method of a kind of river prawn, its concrete grammar is as follows:
(1), the selection of culturing pool: selecting area is 3-4 mu, and the pond of depth of water 1.2-1.8m is as culturing pool, and water inlet and the delivery port in described pond are provided with screen pack, and at the bottom of pond, the mud degree of depth is no more than 15mm;
(2), the sterilization of culturing pool: disseminate the disinfection of 300-400 kilogram of raw lime in 1 circumferential pond, then the water in pond is once changed, each water yield of changing is 50% of pool inner water amount;
(3), before cultivation, prepare: in culturing pool, be placed with aerating machine, every 2-3 days, water carried out to oxygenation once, and plant pasture and water at the bottom of pond, described pasture and water comprise: one or more of hydrilla verticillata, marine alga and pondweed, purify water.
(4), the cultivation of shrimp seedling: select shrimp seedling more than 1.5mm specification to throw in, throwing in density is 10000 tail/mus, in 1-15 days that throw in shrimp seedling, the fish meal of throwing something and feeding, throw something and feed 2-3 every day, each feeding volume is the 4-6% of shrimp seedling weight, in 15-30 days that throw in shrimp seedling, and the soya-bean cake of throwing something and feeding, throw something and feed 3-4 every day, each feeding volume is the 6-8% of shrimp seedling weight, behind 30 days of input shrimp seedling, and throw something and feed tiny trash fish or meat mincing, throw something and feed 5-6 every day, each feeding volume is the 10-12% of shrimp seedling weight, until shrimp seedling cuts one's eye-teeth, then is dragged for and catches listing.
Be different from prior art, the present invention adopts and throw in quicklime disinfection in pond, can ensure the quality of river prawn, Fresh & Tender in Texture, nuisanceless, further improves food security quality, and strengthens autoimmunity and the resistance of river prawn; Be provided with aerating machine and put in pond, in water, do not plant pasture and water, not only can keep the oxygen content in water, can also purify water, thereby improve the survival rate of river prawn; Adopt novel cultural method simultaneously, slowly change to a large amount of high-energy food of throwing something and feeding from a small amount of low-yield food of throwing something and feeding, stimulate the growth rate of river prawn, accelerate river prawn and grow up.
In another preferred embodiment of the present invention, the time of throwing in shrimp seedling is annual April or May.
Further illustrate, annual April or May, weather temperature is gentleer, and temperature stabilization, and fluctuating range is little, thereby makes pool inner water temperature stable, is applicable to shrimp seedling and grows up.
In another preferred embodiment of the present invention, drag for while catching ripe river prawn, adopt cage or fish pot to fish for, and in pond, be sprinkled into benzalkonium bromide in every night.
Further illustrate, benzalkonium bromide can be urged and caught river prawn, accelerates entering the cage time of river prawn.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in the present invention.
