Abstract
The invention discloses a crayfish farming technology, which belongs to the technical field of crayfish farming. The farming technology improves the yield of crayfishes through the preparation of a pond before the stocking and the selection of a stocking mode.
Description
Technical field
The present invention relates to a kind of lobster cultivation technique, specifically is a kind of freshwater lobster cultural technique, belongs to fresh-water fishes shrimp aquaculture technical field.
Background technology
The freshwater lobster protein content is 18.9% to be higher than most fresh water and seawater fishes and shrimps, its amino acid is formed and is better than meat, contain necessary for human body and can not synthesize in the body 8 in essential amino acid, easily by human consumption and absorption, delicious meat also has and prevents the effect that cholesterol is piled up in vivo and be well received by consumers after the food.In recent years, domestic market freshwater lobster sales volume was soaring year by year, and price one rises and rises again, and market conditions are fine always, and always supply falls short of demand for the source of goods.At present, because the fertility of lobster is strong, wide adaptability causes the cultural technique of freshwater lobster also immature, adds random fishing for, and causes the output of freshwater lobster not high.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the invention provides a kind of freshwater lobster cultural technique, the preparation by putting preceding pond in a suitable place to breed and the selection of stocking model can improve the output of freshwater lobster.
The present invention realizes with following technical scheme: a kind of freshwater lobster cultural technique, comprise the preparation of putting preceding pond in a suitable place to breed and the selection of stocking model, and concrete grammar is as follows:
(1) sequencing of preparing according to the requirement of building the pond before putting in a suitable place to breed and disinfecting, foster and apply fertilizer water quality and transplant pasture and water carries out, and is specific as follows:
1) lobster cultivating pool size all can, the ridge is wide 1～2 meter, putting of 0.5 meter high inner wall smooth is set on the ridge jumps wall or the anti-plate of escaping, intake-outlet is equipped with the screen net, putting before the lobster first quarter moon pond in a suitable place to breed puts solid carbon dioxide earlier and cleans up the pond, evenly splash after 75 kilograms of quicklimes of every mu of usefulness are converted water when cleaning up the pond, the back water inlet of 1 week also checks whether also have the wild harmful organisms of predatism such as snakeheaded fish, snake and water mouse in the pond, if have and to remove immediately, whether the toxicity of checking Chi Shui simultaneously disappears, and cultivation water pH value is between 5.8～8.2;
2) under lobster before the pool 3～5 days, every mu of 300～600 kilograms of base manure water inlets of pig manure rich water that applies through fermentation process, transplant pasture and water such as weter hyacinth, water lettuce, pondweed, noodles grass in the pond, the pasture and water coverage rate accounts for 2/3 of the whole pond water surface, net sheet, thick bamboo tube is set, with barrel etc. in the pond;
(2) stocking model comprises 1 year and puts in a suitable place to breed, 1 year results; Breeding in 1 year was filled the gaps with seedlings in 1 year; Directly put into shrimp in a suitable place to breed; Once put seed in a suitable place to breed, mend the little four kinds of patterns of staying greatly:
1) put 1 year results in 1 year in a suitable place to breed: the specification of putting lobster in a suitable place to breed is 90～110 of per kilograms, and the mu stocking rate is at 19～21 kilograms, normal raising through 1 year, do not fish for listing, stay in the pond as using as close shrimp, rise and catch 1 year beginning of spring, catch out shrimp, discovery has embraces the continuation raising of the former pond of putting back to of son, and when catching prawn, the young shrimp amount on the pool is deposited in measuring and calculating, according to the plan of putting in a suitable place to breed, mend out unnecessary young shrimp;
2) directly put into shrimp in a suitable place to breed: mu is put 30～40 of specification per kilograms, reach sexual maturity and become 40～50 kilograms of shrimps, female ratio 1: 5～2: 1, physique stalwartness, no sick and wounded, one-tenth shrimp that body colour is natural are put in requirement in a suitable place to breed, carry out normal feeding and management after putting in a suitable place to breed, do not fish for, allow its mating, lay eggs, breed, survive the winter, catch out shrimp and unnecessary young shrimp 1 year spring, the young shrimp that stays carries out normal management, finally forms prawn;
3) breeding in 1 year, filled the gaps with seedlings in 1 year: this pattern is at the pond that was carried out to shrimp aquaculture in 1 year, after culturing end in 1 year, general mu stays 10～15 kilograms to become shrimp not fish for, close shrimp as 1 year, be allowed to condition at Yuan Chizhong and carry out mating, lay eggs, breeding, 1 year spring, treat to catch out close shrimp after young shrimp breaks away from parent fully, produce young measurement of 200 shrimps according to the female parent shrimp of catching out and calculate the shrimp amount of depositing of depositing the pool, determine young shrimp amount after, raising through 10 days, according to the size of quantity, determine to mend the quantity of putting the shrimp seedling, it is consistent that the shrimp seedling specification Ying Yuyuan that benefit is put deposits pool shrimp seedling;
4) once put seed in a suitable place to breed, mend stay greatly little: the specification of putting in a suitable place to breed is at per kilogram 180～200,15～20 kilograms every mu.
The invention has the beneficial effects as follows: the preparation by putting preceding pond in a suitable place to breed and the selection of stocking model, improved the output of freshwater lobster.
