Abstract
The invention discloses and a kind of improve the female regulation and control method being converted into male efficiency of swamp eel, the present invention is by selecting the suitableeest Regulate Environment, rationally select swamp eel specification, reasonable implementation breeding density, suitably reduce protein content in feed, science feeds, strict control and strengthen regulation and control in spring etc. in time, obtain the high-quality male parent of high-volume, swamp eel is female to be converted into male conversion ratio and reaches more than 78%, male body weight matches with female, meets artificial seed and breeds the demand to male parent.
Description
Technical field
The invention belongs to technical field of aquaculture, be specifically related to a kind of improve that swamp eel is female is converted into male effect
The regulation and control method of rate.
Background technology
Swamp eel is one of important aquatic products of domestic and international market consumption, and supply exceed demand, but seed becomes restriction
The bottleneck problem of swamp eel industry.At present, wild seed cannot meet the demand of culture of swamp eel, it is necessary to solves people
Work seed problem.And solve artificial seed and must first solve the sex reversal of swamp eel.Swamp eel was born to 1 year
The most female, more than 2 ages and 2 ages progressively it is changed into male, some even needs 6-8 to change
For male.Therefore, male is big, does not matches that with female, and production cost is high, and it is artificial to become restriction
One of key factor of seed breeding.In swamp eel seed breeding produces, it is badly in need of solving swamp eel male parent and asks
Topic.
Summary of the invention
It is an object of the invention to provide and a kind of improve the female regulation and control method being converted into male efficiency of swamp eel, this
Bright method includes selecting the suitableeest Regulate Environment, rationally selects swamp eel specification, reasonable implementation breeding density, fits
Preferably reduce protein content in feed, science feeds, strict control and strengthen in time regulation and control in spring etc., it is thus achieved that big
The most high-quality male parent, meets artificial seed and breeds the demand to male parent.
Technical scheme is as follows:
A kind of improving the female regulation 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 does not limits, water
Deep more than 1m, water quality meets country's fishery standard；
2) water body disinfection: pond, irrigation canals and ditches are carried out disinfection by 2-3 month with quick lime, injects new water after 7 days；
Lake, reservoir, rivers need not be sterilized；
3) net cage is arranged: arrange length and width in water body, deeply for the net cage of 2m × 2m × 1m, polythene net
Sheet, square mesh, length of side 1.4mm, uncovered, it is fixed in pond with bamboo or wood, net cage upper end exceeds
Water surface 0.4-0.5m；
4) plantation pasture and water: planting water peanut in net cage, area is the 80% of net cage；
5) eel kind source: the wild or swamp eel of artificial propagation；
6) input specification and the time: put in net cage by the healthy swamp eel that specification is 80g, the release time is
Annual 4-7 month；
7) density is thrown in: input density is 1.5-3kg/, during input, is the iodine of 1/50000 by weight concentration
Solution disinfection 15 minutes；
8) feed: feed kind is expanded pellet feed, earthworm, minced fillet, the protein of expanded pellet feed
Content is 35-38%；
9) feeding method: after eel kind inlet, wild eel the 3rd day, artificial eel threw something and fed the same day earthworm, throw something and feed
Amount is the 0.5% of swamp eel body weight；Wild eel the 5th day, artificial eel the 3rd day increase minced fillet, earthworm, fish
The total feeding volume of Mi is the 1% of swamp eel body weight；Wild eel the 6th day, artificial eel started at the 4th day earthworm and
Increasing expanded pellet feed in minced fillet, the feeding volume of expanded pellet feed is the 0.5% of swamp eel body weight and progressively increases
Add, after the feeding volume of expanded pellet feed increases to the 1% of swamp eel body weight, real depending on Monopterus Albus Feeding and weather
Border situation, earthworm, minced fillet, expanded pellet feed are respectively by 1-1.5%, 1-1.5% and 1-2% of swamp eel body weight
Throwing something and feeding, every day threw something and fed once before darkness；
10) daily management: during property converts, monthly splashing once with quick lime water, quick lime consumption is
0.01kg/m3, late September, the feeding volume of 3 kinds of feeds controls in the 3% of swamp eel body weight, until throwing by the end of October
Feed and terminate；
11) overwinter management: directly surviving the winter in cultivating net cage, the water body depth of water is maintained at more than 1m, if water
Freeze in body and net cage, punching oxygenation of all should opening ice, it is ensured 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
When 18 DEG C, should throw something and feed immediately, start in 4 days after throwing something and feeding, throw something and feed earthworm by the 0.5-1% of swamp eel body weight；
5th day, increase minced fillet and expanded pellet feed, earthworm, minced fillet, the feeding volume difference of expanded pellet feed
For swamp eel body weight 0.5%, 0.5%, 0.25%；From the 6th day, proceed to normally throw something and feed, ingest depending on eel kind
With weather concrete condition, earthworm, minced fillet, expanded pellet feed are gradually increased to the 1-1.5 by swamp eel body weight respectively
%, 1-1.5%, 1-2% throw something and feed, and still throw something and feed once before darkness in every day.
The regulation and control method using the present invention can make that swamp eel is female to be converted into male conversion ratio and reach more than 78%,
Male whose body weight matches with female, it is adaptable to large-scale production.
Detailed description of the invention
Following the present invention is further elaborated in conjunction with the embodiments.
