Abstract
The invention relates to an artificial cultivation method for loach larvae and belongs to the field of aquaculture techniques. The method includes the steps that when natural water temperature is higher than 18 DEG C, mature loaches having robust constitution are selected according to a proportion that the ratio of male loaches to female loaches is 2:1 and serve as parents for copulation and spawning; incubation is carried out under the condition of 25 DEG C water temperature; after larval stage feed is adopted to feed the loaches for 7-10 days, the loaches are transferred into a pond for cultivation until the loaches grow to 1cm long loaches; the 1cm long loaches are cultivated according to a 1:2 pond expansion rate in a pond separation mode until the loaches grow to commodity loaches. The survival rate of the loach larvae can reach above 90%, the survival rate of a larval stage reaches above 75%, the domestic advanced level is reached, scientific bases are provided for research on raising and intercropping of the pond for the loaches, exploration of stocking density, growing periods, growth rates, survival rates of cultivation and input-output ratios of the loaches, and the method has a positive significance in popularization of pond cultivation, yield increase and efficiency increase.
Description
Technical field
The present invention relates to a kind of artificial culturing method of mud fish fry, belong to technical field of aquaculture.
Background technology
Loach is omnivorousness Small Freshwater Fishes, is distributed widely in the ground such as China, Japan, the Korea peninsula, member country of the Commonwealth of Independent States and Southeast Asia., except Qinghai-Tibet Platean, all there is distribution in China in the natural water areas such as the rivers and creeks of various places, irrigation canals and ditches, paddy field, pond, Hu Bo and reservoir, and especially in the Changjiang river and Zhujiang River In The Middle And Lower Reaches, distribution is wide, output is high, is one of important economic freshwater fish.Loach is the famous-brand and high-quality aquatic products kind of high protein, low fat type, and its fine and tender taste, deliciousness are nutritious, have the title of ginseng in water.The edible part of loach accounts for about 80% of whole fish body, higher than general freshwater fish.Therefore, loach is eaten by people for a long time.
China's loach breeding starts from mid-term the 1950's, but culture progress is slow, and scale is also little, and various places disparate development.Many places are still fished for based on natural, propagate artificially still on the back burner.The loach breeding in most area, except part specialist, still pool cultivated comparatively general with the hole of fishing (agriculture) family garden or Around the house, and the technology application that loach is propagated artificially is also not too universal, add that output and benefit all receive certain restriction due to small scale, raiser's dispersion.Particularly in recent years since, owing to fishing for by water pollution, electric power, and using the factor such as the animal feed impact of loach as other special aquaculture objects, the natural resources amount of loach is in downward trend year by year.Along with the adjustment of fish production structure and the rise of special aquaculture industry, although loach breeding is subject to the attention of various places gradually, but its commodity amount still can not meet the growing demand in current domestic and international market, therefore, carry out loach and propagate wide prospect artificially.Current loach is propagated artificially in process, because the wild loach of overfishing causes the yield of natural water area sharply to decline, wild loach resource is more rare, its seed problem has seriously restricted the development of loach breeding industry, the artificial propagation carrying out loach fry has been promote that loach breeding develops in a healthy way, drives the instant task that raiser increases income.
Summary of the invention
The object of the invention is to: provide one that mud fish fry can be made to grow fast, and the artificial culturing method of the high mud fish fry of survival rate.
Technical scheme of the present invention is:
An artificial culturing method for mud fish fry, is characterized in that: it comprises the following steps:
1), when natural temperature is more than 18 DEG C, select the ripe loach of physique stalwartness as parent by the female-male proportion of 2 ︰ 1, injection vinegar Luteinizing hormone releasing hormone makes its mate and oviposit;
2) hatch under water temperature 25 DEG C of conditions after, laying eggs; After the prelarva yolk hatched is eliminated substantially, open-mouthed bait is adopted to carry out feeding;
3), adopt open-mouthed bait feeding after 7-10 days, proceed to pond culture, before spray proceeds to cultivating pool, first cultivating pool is carried out disinfection cleaning, then put into clear water and aquaculture water is flowed slightly,
4) loach water flower, putting into cultivating pool adopts zooplankton to be that feed carries out feeding; Feeding volume every day 3 times, each 2-3 kilograms, strengthen feeding and management, timing inspection simultaneously, and carry out disease control work, until grow up to a cun sheet;
5) mud fish fry, growing up to cun sheet cultivates by the Shuai Fen pool, the expansion pool of 1 ︰ 2, first culture pond carried out disinfection before the loach cun sheet point pool and train the work of water planting fertilizer, and feeding platform is set in culture pond, every day carries out feeding on time according to quantity, carry out daily management, regulating and controlling water quality and disease control work, until grow up to commodity loach simultaneously.
The invention has the advantages that:
The artificial culturing method of this mud fish fry can make mud fish fry survival rate to more than 90%, the survival rate of plantlet stage is to more than 75%, reach advanced international level, for research loach pond master (cover) is supported, explore its density of putting sheep out to pasture, vegetative period, growth rate, cultivation survival rate, input-output ratio provide scientific basis, increasing production and improying productivity to pond culture has positive dissemination.
