Abstract
The invention discloses the breeding method of loach prelarva, April in spring, the ripe loach that when natural water temperature is more than 18 DEG C, selection build is rectified, physique is healthy and strong, mucus is more, healthy nothing is hindered is as parent; With luteotropin releasing hormone d-ala analog (LRH-A
2) and DOM (DOM) hasten parturition; After laying eggs, water temperature 25 DEG C is hatched, and after the hatching of loach seedling after most of prelarva yolk sac disappears substantially, carries out the cultivation of loach seedling; Cultivate to after 7 days, proceed to pond routinely fry culturing technology cultivate.The present invention's egg yolk liquid, juvenile prawn manufactured feed carry out mixing and throw something and feed, meet the nutritional need of loach prelarva opening phase, larvae growth is rapid, overcome the complex process that wheel animalcule is cultivated, whole cultivating process is simple to operate, greatly reduce the amount of labour, under making loach seedling, specification increase is cultivated on the pool simultaneously, improves the survival rate of fry culturing.
Description
Technical field
The present invention relates to the artificial culturing method of a kind of freshwater fish seedling, the breeding method that especially a kind of growth of seedling speed is fast, survival rate is high.
Background technology
Loach (
misgurnus anguillicaudatus), be subordinate to Cypriniformes, Cobitidae, it is a kind of heterophagous Small Freshwater Fishes, its nutrition is very abundant, is known as " in water ginseng ", is the famous-brand and high-quality aquatic products kind of high protein, low fat type, its delicious flavour, fine and tender taste, nutritious, and there is good health value, therefore the dark favor by domestic and international consumers in general, except domestic market demand raises every year, in the international market, loach is also the well sold and in short supply aquatic products that are in great demand, special in Japan, the area, Hong Kong, Macao and Taiwan of Korea S and China is especially welcome.By the impact of state between supply and demand, in the market, loach holds at high price, and in continuing the trend of rise, the mu benefit propagating loach at present artificially has exceeded ten thousand yuan, under the stimulation of high price, propagate loach artificially to develop rapidly, but 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, and 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.
At present; through the continuous effort of aquatic science and technology personnel; cultivate close loach, oxytocic drug selects and compatibility, hasten parturition, hatch and obtained many achievements in research in rearing of fingerling etc.; but in loach fry is cultivated; because open-mouthed bait source is unstable or there is auxotrophy; its prelarva opening cultivates the technical system not yet forming a set of maturation; cause loach artificial breeding too high in opening stage lethality; emergence rate is low; cultivation mud fish fry can not be provided in batches in time, be difficult to form stable scale industry.
Summary of the invention
The object of the invention is: the breeding method that a kind of loach prelarva is provided, make that loach growth of seedling speed is fast, survival rate is high.
Technical solution of the present invention is this breeding method: April in spring, and the ripe loach that when natural water temperature is more than 18 DEG C, selection build is rectified, physique is healthy and strong, mucus is more, healthy nothing is hindered is as parent; With luteotropin releasing hormone d-ala analog (LRH-A
2) and DOM (DOM) hasten parturition; After laying eggs, water temperature 25 DEG C is hatched, and after the hatching of loach seedling after most of prelarva yolk sac disappears substantially, loach seedling adopts open-mouthed bait to cultivate; Cultivate to after 7 days, proceed to pond routinely fry culturing technology cultivate.
Wherein, the long 18cm of female loach body, more than body weight 30g, belly expands softness, high resilience; The long 13cm of male loach body, more than body weight 15g.
Wherein, luteotropin releasing hormone d-ala analog (LRH-A
2) and DOM (DOM) is hastened parturition time, female loach dosage is respectively 20ug/kg and 5mg/kg, and male loach dosage reduces by half, and the used time now joins.
Wherein, open-mouthed bait is: the first selects the yolk boiled, and with double gauze parcel, carries out rinsing, makes egg yolk liquid, be sure not to extrude with hand in egg yolk liquid producing process in water; It two is select the juvenile prawn feed of protein content more than 40%, pulverizes, cross 80 mesh sieves, make juvenile prawn mash feed with cracker.
Wherein, open-mouthed bait is thrown feeding method and is: every ten thousand tail prelarvas every day 0.3 yolk makes egg yolk liquid, and the upper and lower noon respectively throws something and feeds once, and sprayer clean when egg yolk liquid is thrown something and fed is sprayed in rearing pool uniformly; Juvenile prawn mash feed every ten thousand tails every day throw something and feed 1 gram, and point morning, afternoon and evening throw something and feed for three times.
The present invention has following outstanding advantages and technique effect:
(1) the present invention carries out mixing with egg yolk liquid, juvenile prawn mash feed and throws something and feeds in loach larvae cultivation, and meet the nutritional need of loach prelarva opening phase, larvae growth is rapid.
(2) instant invention overcomes the complex process that wheel animalcule is cultivated, pure egg yolk liquid stains the shortcoming of water body.
(3) whole cultivating process is simple to operate, greatly reduces the amount of labour.
(4) under making loach seedling, specification increase is cultivated on the pool, improves the survival rate of fry culturing.
Embodiment
Be further described technical solution of the present invention below in conjunction with specific embodiment, these embodiments can not be interpreted as it is restriction to the technology of the present invention solution.
Embodiment: April in spring, when natural water temperature is more than 18 DEG C, the ripe loach that selection build is rectified, physique is healthy and strong, mucus is more, healthy nothing is hindered is as parent, the long 18cm of female loach body, more than body weight 30g, belly expands softness, high resilience, the long 13cm of male loach body, more than body weight 15g; Hasten parturition with human chorionic gonadtropin (HCG) and luteotropin releasing hormone d-ala analog (LRH-A) compatibility; After laying eggs, water temperature 25 DEG C is hatched, and after the hatching of loach seedling after most of prelarva yolk sac disappears substantially, loach seedling adopts open-mouthed bait to cultivate; Every ten thousand tail prelarvas every day 0.3 yolk makes egg yolk liquid, and the upper and lower noon respectively throws something and feeds once, and sprayer clean when egg yolk liquid is thrown something and fed is sprayed in rearing pool uniformly; Juvenile prawn mash feed every ten thousand tails every day throw something and feed 1 gram, and point morning, afternoon and evening throw something and feed for three times; Nurturing period, note cleaning residual bait, dirt in time, keep water quality good, cultivate to proceed to after 7 days pond routinely fry culturing technology cultivate.
Adopt the loach seedling that above embodiment bait is cultivated, compared with traditional bait yolk, cultivate to its growth performance when 7 days as follows:
