The invention discloses a regulation and control method for improving the efficiency of converting female ricefield eel into male ricefield eel. According to the method, the optimum regulation and control environment is selected, the ricefield eel specification is selected reasonably, the released density is conducted reasonably, and the proper reduction of protein level in fodder, scientific feeding, strict management, reinforcing the spring regulation and control timely and the like are conducted; mass high-quality female parents are obtained, the rate of converting the female ricefield eel into the male ricefield eel reaches 78%, the male individual is matched with the female individual in weight, and the requirement for male parents of artificial ricefield eel breeding is met.
Description
Technical field
The invention belongs to technical field of aquaculture, be specifically related to a kind ofly improve the female regulate and control method being converted into male efficiency of swamp eel.
Background technology
Swamp eel is one of important aquatic products of domestic and international market consumption, and supply exceed demand, but seed becomes the bottleneck problem of restriction swamp eel industry.At present, wild seed cannot meet the demand of culture of swamp eel, must solve artificial seed's problem.And solve the sex reversal that first artificial seed must solve swamp eel.Swamp eel birth was all female in 1 year, and more than 2 ages and 2 ages progressively change into male, it is male that some even needs 6-8 just can change into.Therefore, male is large, and do not match with female, production cost is high, becomes one of key factor that its artificial seed of restriction breeds.In swamp eel seed breeding is produced, be badly in need of solving swamp eel male parent problem.
Summary of the invention
The object of this invention is to provide and a kind ofly improve the female regulate and control method being converted into male efficiency of swamp eel, method of the present invention comprises the suitableeest Regulate Environment of selection, choose reasonable swamp eel specification, reasonable implementation breeding density, be suitable for reducing protein content in feed, science fed, strict control and strengthen in time regulation and control in spring etc., obtain high-quality male parent in enormous quantities, meet artificial seed and breed demand to male parent.
Technical scheme of the present invention is as follows:
Improve the female regulate and control method being converted into male efficiency of swamp eel, it comprises the following steps:
1) water body and water quality: pond, irrigation canals and ditches, lake, reservoir, rivers, size is not limit, more than depth of water 1m, and water quality meets national fishery standard;
2) water body disinfection: 2-3 month carries out disinfection to pond, irrigation canals and ditches with quicklime, injected new water after 7 days; Lake, reservoir, rivers need not be sterilized;
3) net cage is arranged: in water body, arrange length and width, be the net cage of 2m × 2m × 1m deeply, polyethylene mesh sheet, square mesh, length of side 1.4mm, uncovered, is fixed in pond with bamboo or wood, and net cage upper end exceeds water surface 0.4-0.5m;
4) pasture and water are planted: in net cage, plant water peanut, area is 80% of net cage;
5) eel kind source: the swamp eel of wild or artificial propagation;
6) specification and time is thrown in: be that the healthy swamp eel of 80g is put in net cage by specification, the release time is annual 4-7 month;
7) density is thrown in: throwing in density is 1.5-3kg/ ㎡, during input, sterilizes 15 minutes with the iodine solution that weight concentration is 1/50000;
8) feed: feed kind is expanded pellet feed, earthworm, fish gruel, and the protein content of expanded pellet feed is 35-38%;
9) feeding method: after eel kind inlet, wild eel the 3rd day, artificial eel to throw something and feed earthworm the same day, feeding volume is 0.5% of swamp eel body weight; It is rotten that wild eel increased fish the 5th day, manually eel at the 3rd day, and earthworm, the total feeding volume of fish Mi are 1% of swamp eel body weight; Wild eel starts to increase expanded pellet feed in earthworm and fish gruel at the 4th day the 6th day, manually eel, the feeding volume of expanded pellet feed is 0.5% of swamp eel body weight and progressively increases, after the feeding volume of expanded pellet feed is increased to 1% of swamp eel body weight, depending on Monopterus Albus Feeding and weather actual conditions, earthworm, fish gruel, expanded pellet feed are thrown something and fed by 1-1.5%, 1-1.5% and 1-2% of swamp eel body weight respectively, and every day threw something and fed once before darkness;
10) daily management: between property transition phase, monthly splashes once with quicklime water, and quicklime consumption is 0.01kg/m
3, late September, the feeding volume of 3 kinds of feeds controls in 3% of swamp eel body weight, until end of throwing something and feeding by the end of October;
11) overwinter management: directly survive the winter in cultivation net cage, the water body depth of water remains on more than 1m, if freeze in water body and net cage, punching oxygenation of all should opening ice, guarantees that swamp eel normally survives the winter in net cage;
12) cultivate spring in next year: after surviving the winter, at late March or early April in next year, when water temperature rises to 18 DEG C, should throw something and feed immediately, start in 4 days after throwing something and feeding, to throw something and feed earthworm by the 0.5-1% of swamp eel body weight; 5th day, increase fish gruel and expanded pellet feed, earthworm, fish feeding volume that is rotten, expanded pellet feed are respectively 0.5%, 0.5%, 0.25% of swamp eel body weight; From the 6th day, proceed to and normally throw something and feed, ingest and weather concrete condition depending on eel kind, earthworm, fish gruel, expanded pellet feed are progressively increased to respectively and throw something and feed by 1-1.5%, 1-1.5%, 1-2% of swamp eel body weight, still throw something and feed once before darkness in every day.
Adopting regulate and control method of the present invention to make, swamp eel is female is converted into male conversion ratio and reaches more than 78%, male whose body weight and femalely to match, and is applicable to large-scale production.
Embodiment
Followingly the present invention to be further elaborated in conjunction with the embodiments.
