Description
Technical field:
The present invention relates to the method for a kind of artificial bionic state breeding swamp eel seed, belong to fishery science applied technical field.
Background technology:
Swamp eel (Monopterus albus) cultivation is very rapid at China's developed recently, and cultivation producing region spreads all over the country, and in the province such as Hubei, Hunan, Anhui, Jiangxi, Zhejiang of the middle and lower reach of Yangtze River, swamp eel has become its important breed variety.
But develop rapidly in process in culture of swamp eel industry, seed has become the bottleneck of its development, need artificial batch to breed and produced swamp eel seed.And swamp eel due to its reproductive biology special; carrying out seed breeding adopts the method for the artificial induced spawning of large fish unworkable in production; need to find a kind of method that can be suitable for swamp eel reproductive biology characteristic to carry out breeding of swamp eel seed, to meet culture of swamp eel scale and industrialization to the requirement of seed.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of artificial bionic state to breed the method for swamp eel seed, in enormous quantities, high-quality swamp eel prelarva seed can be provided, to meet the requirement of large-scale cultivation swamp eel to seedling.
The present invention realizes above-mentioned purpose by following technical solution.
The method of a kind of artificial bionic state breeding swamp eel seed provided by the invention, comprises the steps:
(1) selection of parent and cultivation:
1. the selection of parent: 2 ages that breeding obtains with the artificial propagation of swamp eel Juvenile stage are individual, kind is macula lutea eel that is yellow, surface spot sparse distribution;
2. the cultivation of parent:
The cultivation of parent is divided into 3 stages;
First stage is 7 ~ November then, and the breeding method in this stage is: adopt pond net box to cultivate, parent's breeding density is 2 ~ 5kg/m
2, feed adopts the mixture of animal feed and manufactured feed; The ratio of animal feed and manufactured feed is 4 ~ 5:1, and animal feed selects water earthworm, earthworm or silver carp mince; Day feeding volume is 8% ~ 10% of swamp eel body weight; Time to mid-November water temperature drop to 15 DEG C, stop throwing something and feeding to parent, and be allowed to condition at overwintering in pond net box;
Second stage is proceed to Ecology to swamp eel parent after surviving the winter to breed the stage before pond; The breeding method in this stage is: when swamp eel survives the winter and rises to Second Year early April water temperature and be stabilized to more than 15 DEG C, refeeding, and feed of throwing something and feeding uses animal feed completely, selects earthworm or water earthworm, feed day feeding volume be 3% ~ 5% of swamp eel body weight; Proceed to Ecology breeding pond in preparation within first 7 days, to stop throwing something and feeding;
Phase III is that swamp eel parent proceeds to the stage after the net cage of Ecology breeding pond from pond net box; The breeding method in this stage is: proceed to second day after the net cage of Ecology breeding pond from pond rearing net cage until swamp eel parent, start feed of throwing something and feeding, feed still uses animal feed completely, select earthworm or water earthworm, feed day, feeding volume was 8% ~ 10% of swamp eel body weight, until after the swamp eel parent egg-laying period terminates, stop throwing something and feeding;
(2) Ecology breeds selection and the preparation in pond: swamp eel Ecology is bred pond and selected low-lying rice field or pond, and the soil property in breeding pond is loam, and water-tight, water retention property is good, abundant water, and irrigation and drainage are convenient, pollution-free, and surrounding environment is quiet; Before embedding breeding net cage, overall leveling to be carried out to breeding pond, consistent to guarantee that the water level after at the bottom of pond imbedded by breeding net cage;
(3) design and the layout of net cage is bred: the net cage area of breeding is 1.5m
2, high 80cm; Form with mesh 20 object Polyethylene netting processing and fabricating; Net cage is embedded in Ecology breeding pond, every 667m
2area can bury net cage 400-410 underground; Net cage inner bottom part is embedded in mud, and mud is 25cm deeply, and the pond depth of water is 5 ~ 8cm, floats and plants Eichhornia crassipes, be commonly called as weter hyacinth in net cage, its natural ecological environment imitative; The area of Eichhornia crassipes accounts for 1/2 of net cage inner area, perches and lay eggs for yellow eel;
(4) input of parent and male and female are arranged in pairs or groups: the release time of parent is between annual 20 ~ May 10 April, and water temperature is more than 22 DEG C, and fine day is thrown in; The body length of dam's eel individuality is 20 ~ 30cm, body weight is 75 ~ 100g; The body length of male close eel individuality is 40 ~ 50cm, body weight is 100 ~ 150g; At 1.5m
2net cage in can put the male eel of the female eel of 2 ~ 4 tail and 2 ~ 3 tails in a suitable place to breed;
(5) the laying eggs and hatch of swamp eel: annual late May, namely enter yellow eel breeding season, close eel beginning tells foam and nests, after nesting 2 ~ 3 days, and yellow eel starts to carry out natural spawning fertilization, can see yellow eel ovum in nest; In yellow eel reproductive process, not artificial disturbance swamp eel, otherwise ovum can be swallowed in mouth by swamp eel; Fertilized egg adopts the mode of hatching naturally in breeding net cage to hatch, if incubating oosperm leaves fish nest, its incubation rate is very low;
(6) collection of swamp eel seedling: when water temperature 28 DEG C ~ 30 DEG C, after swamp eel is nested 7 ~ 10 days, eel seedling can hatch, and now yolk sac does not also disappear, and eel seedling can agglomeratingly be attached on the coring of Eichhornia crassipes, collected eel seedling in time, was separated by eel seedling with close eel.
The present invention compared with prior art; the reproduction rate of swamp eel can reach 80% ~ 90%; the incubation rate of natural spawning fertilization can reach more than 98%; prelarva seed collection rate can reach more than 95%; in enormous quantities, high-quality swamp eel prelarva seed can be provided; to meet the requirement of large-scale cultivation swamp eel to seedling, there is extraordinary application prospect.
Embodiment:
Implement the present invention, for Jianghan Plain, can carry out according to the following steps:
