Abstract
The invention discloses the cultivating and managing methods of male swamp eel parent a kind of, Nature enemy is carried out to the female eel after oviposition, prolonged nutritional deficiency can lead to the degeneration of ovary, simultaneously with the appearance of male characteristic, dark processing is carried out during Nature enemy, effectively facilitate the secretion of melatonin in night Monopterus Albus, reduce the diurnal fluctuation of melatonin level in Finless Eel Monopterus Albus, to promote the sex reversal of swamp eel, so that sex reversal growth is consistent in swamp eel group, and protein content in feed is controlled in overwintering preceding cultivating process, swamp eel is set to be basically completed sex reversal, again after spring in next year cultivates, swamp eel parent's male ratio reaches 95% or more, the consistent male swamp eel parent of growth specification can be obtained in batches.
Description
Technical field
The present invention relates to technical field of aquaculture, in particular to a kind of three-dimensional polyculture method of swamp eel loach.
Background technique
Swamp eel is one of the important aquatic products of domestic and international market consumption, and supply exceed demand, but seed becomes restriction swamp eel production
The bottleneck problem of industry.Currently, fish wild seed is unable to satisfy the demand of culture of swamp eel, it is necessary to solve the problems, such as artificial seed.Swamp eel with
Other fish have a very big difference, i.e. sexual reversal phenomenon.In nature, swamp eel is entirely raun at the initial stage of life, must
It must be after breeding at least once, raun can just be converted to milter.In the swamp eel propagated artificially at present, as long as the fingerling launched
Specification is in 15 tails/jin hereinafter, then almost all is raun.It is bred to the large-scale artificial of swamp eel, must just carry out swamp eel
Parent population is specially cultivated.
Swamp eel is born to being entirely female in 1 year, and 2 ages and 2 more than age are gradually changed into male, some even need 6-8
Nian Caineng is changed into male.Therefore, male is big, does not match that with female, high production cost, becomes and restricts its artificial seed
One of key factor of breeding.In monopterus albus fry breeding production, urgent need solves the problems, such as swamp eel male parent.
Summary of the invention
The present invention provides the cultivating and managing methods of male swamp eel parent a kind of, promote the sex reversal of swamp eel parent, batch
The consistent male swamp eel parent of growth specification is obtained, solves the problems, such as male parent in swamp eel reproductive process.
In order to achieve the above objectives, the invention adopts the following technical scheme:
A kind of cultivating and managing method of male swamp eel parent, comprising the following specific steps
(1) training orientation of postpartum female eel:
After having spent swamp eel breeding period, swamp eel after oviposition is caught out, and select individual weight in the female eel of 60-80g in month current year 7-9
It launches in pond net box, the stocking rate of each net cage is 3.5-4kg/m2, and be sieved with sub-sieve device, accomplish that eel kind is advised in same case
Lattice is originally consistent, and after feeding 10-15 days in female eel investment net cage, is carried out 5-6 weeks Nature enemy, is during which carried out to net cage
Continuous 1 week shading dark processing is accelerated postpartum female eel and is changed to male；
(2) overwintering preceding culture:
Later to swamp eel refeeding after starvation, timing daily, fixed point feed bait, and feed is using fresh animal bait and cooperation
Feed is mixed according to the ratio of 3-5:1, and the mixed feed is existed using swelling soya dreg, rice bran, white fish meal composition, protein content
30-35% is cultivated to November current year, is stopped feeding, swamp eel enters Wintering Period, and the overwintering in pond net box；
(3) spring in next year cultivates:
After overwintering, when April in next year, water temperature rose to 16 DEG C or more, start to be fed, the spermary of swamp eel starts to send out at this time
It educates, starts in feed 1 week, feed the bait such as fresh earthworm, screw meat according to the 0.8-1.5% of swamp eel weight, start to add later
Enter swamp eel special compound feed, the amount of addition sequentially progressive method gradually increases daily, be gradually increased to mixed feed with
The ratio of fresh and alive feed is in 1:(1.5-2) standard, feed culture to 5-6 month, swamp eel testis development is mature, can be transferred to numerous
It grows in pond.
Wherein, feeding volume is the 2.5-4% of swamp eel weight after step (2) refeeding, according to the intensity of feeding, remains material
Situations such as adjust feeding amount in time, Feeding time is controlled in daily 8:00-9:00,18:00-19:00.
Wherein, swamp eel special compound feed main component includes swelling soya dreg, rice bran, white fish meal, answers in the step (3)
Close vitamin, composite mineral matter, protein content 38%-40%.
Wherein, water peanut is planted in the net cage, cultivated area accounts for the 50-60% of net cage area.
The present invention has the beneficial effect that:
Nature enemy is carried out to the female eel after oviposition in the present invention, prolonged nutritional deficiency can lead to the degeneration of ovary, simultaneously
With the appearance of male characteristic, dark processing is carried out during Nature enemy, effectively facilitates melatonin in night Monopterus Albus
Secretion, reduce Finless Eel Monopterus Albus in melatonin level diurnal fluctuation, to promote the sex reversal of swamp eel, so that in swamp eel group
Sex reversal growth is consistent, and protein content in feed is controlled in overwintering preceding cultivating process, turns being basically completed property of swamp eel
Become, then after spring in next year cultivates, swamp eel parent's male ratio reaches 95% or more, the growth consistent male of specification can be obtained in batches
Swamp eel parent.
Specific embodiment
Embodiment 1
A kind of cultivating and managing method of male swamp eel parent, comprising the following specific steps
(1) training orientation of postpartum female eel:
Month current year 7-9 after having spent swamp eel breeding period, swamp eel after oviposition is caught out, and selects female eel of the individual weight in 75g and launch
Into pond net box, water peanut is planted in net cage, cultivated area accounts for the 60% of net cage area；The stocking rate of each net cage is
