The method comprises the steps of breeding pond preparation, food organism culture, parent shrimp selection and breeding, young shrimp breeding, water quality management and young shrimp fishing. The method for intensive breeding and young shrimp culture of the freshwater shrimps has the advantages that production resources are fully utilized, professional devices are not needed, the method is free of culture pollution, a cultivation technology is standard, the feeding is scientific and normative, the quality of the young freshwater shrimps is greatly improved, and accordingly the quality and yield of the freshwater shrimps are improved.
Description
Technical field
The present invention relates to the technical field of aquaculture, be specifically related to the intensive breeding and seedling method of freshwater shrimp.
Background technology
Freshwater shrimp bodily form tubbiness, whole health is made up of cephalothorax and belly two parts.Cephalothorax respectively saves joint, covers back of the body side and both sides, be carapace or carapace by a macrosclere.Cephalothorax is thick, and abdomen front portion is comparatively thick, and rear portion is thin and narrow and small gradually.Frontal eminence is positioned at cephalothorax front center, and upper limb is straight, and end is sharp-pointed, and there is xiphoid carapace front end, upper limb have 11 ~ 15 red, lower edge has 2 ~ 4 teeth.Body colour is usually cyanic colours and has brown-green speckle, but often changes along with habitat.The body surface of freshwater shrimp has hard shell, plays a part to protect body, and its entirety is made up of 20 body segments, and head 5 saves, and chest 8 saves, and belly 7 saves, and sharply can shrink, tail fan drying retreats, have step 5 right with belly, and front 2 in pincerlike, and rear 3 to one-tenth claw-like.Wherein the 2nd pair of step of male shrimp is powerful especially, freshwater shrimp nutritious, and meat is soft, easy to digest, to in poor health and need the people taken good care of to be fabulous food after being ill: containing abundant magnesium in shrimp, magnesium has important regulating action to cardiomotility, well can protect cardiovascular system, it can reduce blood cholesterol level, prevent arteriosclerosis, simultaneously can also coronary artery dilator, be conducive to preventing hypertension and myocardial infarction: the logical breast effect of shrimp is stronger, and be rich in phosphorus, calcium, to children's, pregnant woman has help effect especially: the scientist of Osaka, Japan university finds, astaxanthin in shrimp body contributes to eliminating " jet lag " that produce because of jet lag, the cultural technique that the freshwater shrimp of current existence is propagated artificially is still more traditional, and especially in the cultivation of the shrimp seedling of freshwater shrimp, disease is serious, and the survival rate of cultivation is extremely low, the serious desire of having attacked the cultivation of raiser and enthusiasm.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of can carry freshwater shrimp Quality of Seedlings and the intensive breeding and seedling method of scientific and normal freshwater shrimp.
Technical problem to be solved by this invention realizes by the following technical solutions.
The intensive breeding and seedling method of freshwater shrimp, is characterized in that: comprise the following steps:
(1) preparation in pond, is bred:
A. the condition in pond is bred.The area that freshwater shrimp breeds pond is advisable with 0.2-0.3 hectare, depth of water 1.0-1.2m, and slope, pond ratio is 2.5-3.0:1, arranges collection shrimp pool 20-30 square metre at discharge outlet place.Breed pond should select to have abundant water resources, water quality is pure and fresh and pollution-free, and irrigation and drainage are location easily.
B. leveling of pond is bred.The work such as to tan by the sun breeding the transformation of first 1 month of shrimp seedling and the dry pool, throw in oogenesis parent shrimp first 15 days, first by pond water filling about 10cm, pond disinfection is carried out by 200kg/ mu quicklime, within after cleaning up the pond 5-7 days, start water inlet, water level, about about 80cm, enters the 80-100 order silk cover filtering that discharge outlet is double-deck, breeds in pond in case the harmful organisms such as wild fishes, frog's egg enters.
(2), the cultivation of food organisms: 5-7 days before putting oogenesis parent shrimp in a suitable place to breed, breed pond should apply fermentation after fertilizer 300-500kg/ mu.
(3), close shrimp selection with breed:
A. the selection of close shrimp.Catch from the large water surface such as lake, reservoir, irrigation canals and ditches, pond in mid or late May.Select that action is active, complete, the individual body of limbs reaches more than 5cm, ovary requirement is ripe or connect maturescent female shrimp as close shrimp, its whole back side of Ovarian Volume nearly cover, frontal eminence base portion is arrived in front end, and the color of ovum be green or orange colour.The stocking rate of oogenesis parent shrimp is 8-10kg/ mu.
B. the breeding of shrimp seedling.Be 0.5cm by mesh, height is the polyethylene mesh sheet of 1.2m, and the base of mesh sheet to be imbedded in mud and compacting, enclose one jiao that blocks in pond, area is 50-60 square metre, along one week fresh water plants of input of purse seine, account for the 20%-30% of the water surface in purse seine, oogenesis parent shrimp is put into purse seine and cultivates.Parent shrimp checks the developmental state of shrimp ovum every day, treats that zoea all departs from parent after throwing in, close shrimp is pulled out listing with the instrument of fishing for such as lobster basket, now, cultivate the fertilizer after applying fermentation by 150-200kg/ mu in pond, continue the food organisms cultivating shrimp seedling.
C. the zoea in purse seine, the rotten and yolk cultivation with ripe fish, fish gruel is with yolk all to splash after 60-80 order silk cover filterings, and one day 4 times, every ten thousand shrimp seedlings are thrown something and fed with fresh fish 0.5kg and 2, yolk.Zoea was through the reinforced cultivating of a week, and its body is long reaches 0.5cm, can remove purse seine gently and carry out seed rearing.Seed rearing changes fish gruel in earlier stage and yolk is soya-bean milk, wear into soya-bean milk with soya bean 3kg-4kg/ mu every day to divide and throw something and feed for 3 times, after within 15 days, cultivating, shrimp seedling body reaches about 1cm, except throwing something and feeding every day except soya-bean milk, increasing throws something and feeds into work manufactured feed, feeding volume accounts for shrimp body body weight about 5%, throws something and feeds every day 2 times, and the morning, feeding volume accounted for 20% of whole day feeding volume, afternoon, feeding volume accounted for 80%, and threw something and fed along pool side shallow water area multiple spot fixed point.
(4), water quality management
A. guarantee have abundant food organisms, sufficient dissolved oxygen and suitable acid-base value.Water quality should be regulated in time according to the food situation of water colour, transparency and shrimp seedling, strengthen the scientific management of water quality.
B. apply fertilizer and note draining.Controlling well while pond waters fertilizer degree, also will meet shrimp seedling and to ingest the growth needs of natural bait biology, a fertilising in month 2-3 times, applies fertilizer 150-200kg at every turn.The freshwater shrimp seed rearing later stage pond depth of water need be added to 1.0-2.0m.
C. water body ph>7.0 value is regulated.Test weekly the acid-base value of 1 water body, if ph<7.0, then use quicklime 5kg/ mu full pool spilling head.
(5) shrimp seedling is fished for
When freshwater shrimp seed body reaches 1.5-2.0cm, carry out a point pool, pull out gently with fry net, or carry out lamp light trapping, the triangle fishing net adopting 30-40 mesh sieve thin,tough silk to be made into, repeatedly copies at pool side and catches.
The water plants thrown in described step (3) is pasture and water, weter hyacinth, water peanut.
The invention has the beneficial effects as follows: the present invention make use of the resources of production fully, without the need to professional equipment, pollute without cultivating, Cultivating techniques standard criterion, throwing is raised scientific and normal, improves the quality of freshwater shrimp significantly, thus improves the quality and yield of freshwater shrimp.
