Description

A kind of fry cultivation control method
Technical field
The present invention relates to a kind of fries to cultivate control method, belongs to fish culture technical field.
Background technique
Fish are the best source of animal protein of the mankind, and however as the increase of mankind's activity, natural fishery resources are Through starting to be unable to satisfy consumer need.Fry cultivation is a ring the most basic during fishery cultivating, fish in the prior art Seedling cultural method, fry growth is slow, and seed size is small, can only support within 1 year one season fish, economic benefit of aquaculture is influenced, if but passing through The mode of fattening accelerates the growth of fry, then mismatches needed for the growth because of fry with nutrition supply, fry is liable to illness, shadow Ring its survival rate.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of fries to cultivate control method, with On the basis of survival rate of fish fry, accelerate fry growth rate, to realize fish culture mode in two seasons of one year.
To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of ecology fry cultivate control method, by with Under several aspects realize:
(1) bait controls: just start to feed egg yolk after fry pond-inputting, soya-bean milk is changed to after 3-6 days and is fed, when spray is grown to 2cm, Particulate material is replaced with puffing material, and adds immunopotentiator in conventional bait, additive amount is the 3-5% of conventional bait amount, and Reduce within preceding 1-2 months the 2-3% of day feeding volume to fish body weight, subsequent incremental increase feeding volume, every two weeks to 1 month Increase feeding volume is primary, and each increased feeding volume is the 0.3-0.5% of fish body weight；Wherein immunopotentiator is by following parts by weight Raw material be formulated: 5-10 parts of multi-vitamins, 15-20 parts of sweet wormwood, 20-25 parts of Radix Astragali, 20-25 parts of wilsonii, garlic 15- 25 parts, 10-15 parts of antibacterial peptide, wherein multi-vitamins are vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin E, inositol, niacinamide and pantothenic acid mixture；
(2) water correction: before fry is launched, apply green manure, muck toward fish pond, zooplankter and algae are cultivated, to fry pond-inputting After it is primary every 3-5 days new water of filling, the old water of discharge, and observe fry activity condition and carry out top dressing in time, generally every 3-5 Its top dressing is primary, and fertilizer is organic fertilizer, and when top dressing splashes uniform；Daily oxygenation at least once, and throws beneficial microbe, reduces Ammonia nitrogen in water；
(3) control of fish disease epidemic season: left and right, which starts to feed, one month earlier is mixed with the bait that gallbladder drug is protected in liver protection, often 100kg fish admixes 8-15g with bait, and it is female by 15-20 parts of Radix Isatidis, 15-25 parts of selenium-rich oat, benefit that wherein gallbladder drug is protected in liver protection 25-35 parts careless, 10-18 parts of Poria cocos, 20-25 parts of three bloom, 20-30 parts of Radix Glycyrrhizae mix；In period in White Dew, should suitably control The food amount of fish processed, reduction bait feeding amount to the 3% of fish body weight, and accomplish periodically to apply quick lime regulating water quality, it to control as far as possible Water level processed adheres to patrolling the pool sooner or later, increases time of daily oxygenation to 2-3h.
Compared with prior art, the beneficial effect that the present invention has is:
1, through the invention several aspects control, not only ensure that survival rate (90% or more), but increase yield (more than 1000 jin/ Mu), fattening method compared to the prior art breed fish seedling yield (about 500-600 pounds/acre) for, yield is double；
2, control through the invention, fry specification put the fry of this specification, the growth of coming year adult fish in a suitable place to breed up to 1-1.5 jins/tail Period to listing specification is short, can with 1 year support two season fish, change East China 1 year one season aquaculture model.
Specific embodiment
Presently in connection with specific embodiment, next the invention will be further elaborated.
Embodiment one (Hunan Anxiang fishing ground)
