Abstract
The invention relates to the field of agricultural culture, and provides a cherax quadricarinatus imitative ecological artificial scaled incubation culture technology. The technology is particularly applicable to domestic gannan area climate culture, and fills the blanks in China. According to the technology, the complete ecological imitating incubation culture of the cherax quadricarinatus, particularly chrtax quadricarinatus is realized. Along with the lobster fertilization, before the stocking of lobster seeds into a pond, the sizes of stones, silts and water plants in an incubation pond are continuously changed for adapting to the growth of lobster seeds; the temperature and the diet are synchronously and scientifically managed; particularly through the unique design of the pond, the bottom layer is underground water, the top layer is flowing spring water, and the middle is water with proper water temperature; three kinds of different ecological environments provide the complete growth environment for the lobster; through the culture by the technical scheme, the cherax quadricarinatus can be cultured to be heavier than 0.8kg.
Description
Technical field
The present invention relates to agricultural breeding field, be specifically related to Australia freshwater lobster cultivation.
Background technology
Australia freshwater lobster originates in Oceania, is in recent years from the large-scale fresh water shrimp of one that Australia introduces, comprises red claw crayfish and Ya Bie crayfish two kinds.Australia freshwater lobster has another name called red claw crayfish, formal name used at school Cheraxquadriarinatus.Originally be wild shrimp, 1971 start to propagate artificially, are one of current Freshwater shrimps the most excellent in the world.This shrimp lives in fresh water throughout one's life, omnivorousness, has growth rate faster, natural propagation can hatch in fresh water, there are higher survival rate and stronger resistance against diseases, aggressive weak, lower oxygen concentration resistance, resistant, strong adaptability and fine and tender taste, delicious flavour, edible ratio high (belly accounts for 42% ~ 47% of TBW), and there is resistance to long-distance transport, can fresh and alively go on the market, artificial propagation equipment is simple, low cost and other advantages.Support research according to aquatic products research institute of Beijing to introduction two kinds of Australia freshwater lobster examinations, red claw crayfish growth rate is faster than the other crayfish of tooth, and the other crayfish low temperature tolerance ability of tooth is stronger than red claw crayfish.
Cultural technique is not overripened within Chinese territory now for Australia freshwater lobster, lack a whole set of standard, and the shrimp seedling of Australia freshwater lobster is often extremely just extremely a sheet of, very large to the economic pressures of raiser, in the urgent need to the cultural method that a set of Australia freshwater lobster is domestic, because various places weather is different, especially area, south, Jiangxi is still blank at present.
Summary of the invention
The object of the invention is to overcome above-mentioned technical problem, a kind of Australia freshwater lobster Ecology artificial scale hatching cultural technique being provided, being especially adapted to the local climate cultivation of south, domestic Jiangxi, filling the domestic gaps.
Technical problem of the present invention is solved mainly through following technical proposals:
Australia freshwater lobster Ecology artificial scale hatching cultural technique, is characterized in that, comprise the following steps:
(1) the parent mating stage: get more than three liang limbs and perfect strong public shrimp one, get more than two liang limbs and perfect strong female shrimp three, jointly be placed in hatchery, 20 ~ 25 DEG C of clear water are put in hatchery, when described female shrimp is together with male shrimp, its afterbody needs to turn always backward, within about 15 days, complete mating, be eliminated having a female shrimp and be subject to the attack of male shrimp, superseded female shrimp is separately taken away;
(2) 15 ~ 30 days: implement Ecology hatching, in hatchery, increase river sand, handstone, pasture and water, after becoming pregnant two female shrimps start to hide male shrimp, within about 5 days, occur oophyte, oophyte is without color, and hatchery water temperature increases gradually, rises to 25 ~ 30 DEG C by initial 20 ~ 25 DEG C;
(3) 30 ~ 45 days: its oophyte of female shrimp becomes reddish yellow, needs feeding evening once, main food materials egg yolk, brown sugar, oatmeal, pumpkin, water temperature need keep 25 ~ 30 DEG C;
(4) fourth stage: about 50 days, oophyte turns white band stain and eyes, and temperature need rise to some extent, keep about 30 DEG C, have more meals a day but less food at each, main food materials soybean curb residue, egg yolk, 3 ~ 4 times on the one, 60 ~ 70 days, oophyte two eyes out, and wriggling of stretching one's legs, Automatic-falling, namely Yu 10% needs when not coming off manually to help shrimp seedling to separate with parent in time, only stays shrimp seedling during Jie in hatchery, avoids female shrimp to eat shrimp seedling;
(5) grow seedlings the stage: be cooled to about 20 DEG C to hatchery, exchange well water for successively, keep Ecology environment in hatchery, one Zhou Huanshui once, shrimp seedling shelling in 5 ~ 6 days early stages, ten to fifteen days in later stage, each shelling is just grown up once, needs careful cleaning shell consider to be worth doing and increase corresponding larger stone, pasture and water, to ensure shading rate;
(6) pool stage is thrown: shrimp seedling is grown up about 50 days can throw the pool, and need ensure that pond water temperature and hatchery water temperature are more or less the same, being generally selected in 3 ~ April of spring, is secondly 9 ~ October of autumn, supports to six months, and shrimp grows to 2 ~ 3 all right one way or the other listings;
(7) the pond culture stage: 1.5 meters, pond is dark, bottom need have been chosen well water and infiltrate geology, and top layer needs external movable mountain spring water, and centre is the transitional horizon of proper temperature, upper, middle and lower three layers of water quality and different temperatures environment need be built in pond, and bottom has also needed stone, river sand and pasture and water plantation.
Further, described hatchery need continue oxygen supply.With shrimp seedling developmental process, in hatchery, fine sand increases thicker river sand gradually.Oophyte incubation period need inject new water once in one week.
The invention has the beneficial effects as follows: Ecology hatching cultivation Australia freshwater lobster completely, especially red claw crayfish.Before lobster becomes pregnant and put pond in a suitable place to breed to shrimp seedling, constantly stone, silt, pasture and water size in change hatchery, to adapt to the growth of shrimp seedling; Synchronous scientific management temperature and meals, especially the unique design in pond, bottom underground water, top layer flowing mountain spring water, middle suitable water temperature and quality, three kinds of different ecological environment provide the perfect growing environment of lobster, Australia freshwater lobster can be cultivated to one jin more than six liang through technical solution of the present invention cultivation.
