Abstract

The invention discloses a kind of cultural methods of cray, the present invention uses mixed breed, make full use of Water space, loach belongs to lower floor fish, silver carp belongs to midwater fishes, recipe is wider, different growth periods is fed using the animal bait and vegetal bait of different ratio, more targetedly, it can preferably be combined between each ingredient, effectively improve infiltration rate and the speed of growth of the cray to bait, on the one hand the water plant of transplanting can be used as food, on the other hand it can be provided for cray and hide place, the present invention cultivates cray health, it is individual big, integrated culture can also improve unit waters and originate in simultaneously.

Description

A kind of cultural method of cray
Technical field
The present invention relates to aquaculture field, more particularly to a kind of cultural method of cray.
Background technology
Lobster is because delicious flavour, full of nutrition and favored by consumers in general, due to huge market, from And lobster cultivation is made to become a kind of industry.Currently, the cultivation of lobster cultivates for wide in range property, i.e., it is existing in suitable water surface free-ranging Some cultivation have the following problems:Size is raised together, and Individual Size is uncontrolled;Daily ration, feeding quantity is not easy to hold, and often results in waste.
But monoculture lobster, yield is not high, leads to economic benefit not and be fairly obvious, and water body utilizes 60% quilt of space Waste.Effectively to solve the problems, such as this, researcher begin one's study fish and lobster mixed breeding.In being due to the fish products kind put in a suitable place to breed, on Layer fish, lobster activity is in bottom.Therefore, it is effectively utilized Water space, improves the productive potentialities and output capacity of water body, is increased Culture efficiency is added.Especially lobster cultivates, and bottom water resource is utilized, and seedling is easy to solve, and aquaculture cost is low, and risk is small, Market conditions are good, and synergy is apparent.
Invention content
The purpose of the present invention is to provide a kind of cultural methods of cray, make full use of Water space, improve cray Calcium content, promote the speed of growth of cray, increase the output in unit waters.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of cultural method of cray, includes the following steps:
(1) cultivating pool selects:Choose bottom of pond is flat, have abundant water resources, water quality is good, top width 3-5 meters of the pond ridge, the gradient 1:3、 Area is 5-7 mus, the rectangle pond of 1-2 meters of the depth of water;
(2) water body is handled:Per acre the water surface with quick lime 100kg it is soluble in water after, full pond is uniformly splashed, and full pond disinfection is carried out Processing;
(3) water plant is transplanted:Water peanut and rye grass forage grass are planted in pool side, breeding water hyacinth and water spinach on the water surface, Shoal plants barnyard grass, and in pond, surrounding plants tea tree;
(4) fry is put in a suitable place to breed:It is put into fry when first spring fine day water temperature is 8-11 DEG C, fry is embathed with 3-4% saline solutions 5-10 minutes, put 70-100kg/ mus of weight in a suitable place to breed;
(5) shrimp seedling is launched:Shrimp seedling to be launched at the beginning of 4 months disposably enters pond, shrimp seedling specification is 2-3 centimetres, shrimp seedling is physical strong, Appendage, vitality are strong, with 2-3% salt water dipping baths 6-10 minutes, launch 60-70kg per acre;
(6) feeding management:3 bait are launched daily, and the release time is 8 points, 16 points, 24 points, and bait throwing in ratio is that bait accounts for Deposit the 3%-5% of pond shrimp gross weight;Forward and backward phase plant feed accounts for 60%, and mid-term animal fodder accounts for 60%, animal fodder choosing 6 parts of 4 parts of trash fish and spiral shell meat are selected, plant feed selects 3 parts of duckweed, 6 parts of corn flour, 4 parts of chick-pea, 6 parts of cucumber, peanut cake 4 parts, 5 parts of wheat bran, 3 parts of burdock;
(7) water quality management:Every 5-10 days, by the sludge removal in pond bottom groove, and the new of 1/5-1/3 is injected Water changes after water and discharges aquatic biological fertilizer and quick lime again so that the pH of water is 7-8.5 in shrimp ponds, and carries out oxygenation to water, is ensured Amount of oxygen is in 5.0-6.0mg/L in aquaculture pond.
Preferably, step (7) applies quick lime 8-12kg per acre.
Preferably, step (4) described fry includes loach and silver carp.
Beneficial effects of the present invention:The present invention uses mixed breed, and Water space, loach is made full use of to belong to lower layer fish Class, silver carp belong to midwater fishes, and recipe is wider, and different growth periods uses the animal bait and vegetalitas bait of different ratio Material is fed, and more targetedly, can preferably be combined between each ingredient, be effectively improved infiltration rate of the cray to bait And on the one hand the speed of growth, the water plant of transplanting can be used as food, on the other hand can be provided for cray and hide place, the present invention It is big to cultivate cray health, individual, while integrated culture can also improve unit waters and originate in.
Specific implementation mode
The invention will now be further described with reference to specific embodiments, but examples are merely exemplary, not to this hair Bright range constitutes any restrictions.
