Abstract
The invention relates to the field of marine fish culturing, and discloses an indoor water segmented marine fish fry breeding method. The method comprises the following steps: (1) fish eggs are hatched; (2) fish fries are cultured. According to the invention, a hatching pool and a nursery pool are separately arranged. Water is purified in advance, and various biological feeds are cultured in advance, such that living conditions in the hatching pool and the nursery pool are regulated, and a relatively stable circulation water condition is provided. No drug such as hormone or antibiotic is needed to be added during the hatching and fish fry breeding processes. Physical and chemical factors such as the temperature, pH value, dissolved oxygen, salinity, and the like of the water in the hatching pool and the nursery pool can remain relatively stable. The water quality is maintained stable, and the fish fries are prevented from having stress responses and drug resistance. A survival rate of the fish fries can reach approximately 14%.
Description
Technical field
The present invention relates to mariculture field, refer to a kind of indoor water body segmented ocean fish fry mating system especially.
Background technology
It is one of important link of mariculture that fry breeds.Annual 3-11 month is the peak period that various fish hatches, breeds.Hatch fish roe, breed the control of water quality, water temperature and harmful organisms is all had higher requirements.As long as an aspect goes wrong, just may cause the failure of whole hatching process, bring loss difficult to the appraisal, also seriously constrain the development of whole mariculture industry.Therefore, fry hatching, to breed be that ocean fish propagates one and important link artificially.Existing hatch fish roe mating system, generally all carries out in outdoor, and water temperature, illumination, throwing eating capacity adjusting and controlling difficulty are comparatively large, and hatch, breed condition very easily by the impact of natural environment, hatching survival rate maintains about 4% mostly.Whole reproductive process needs to use a large amount of medicines to carry out the maintenance of various disease prevention and cure and water body environment.And the use of medicine, although fry survival rate can be improved, but the fry cultivated is strong to drug dependence, resistance against diseases is weak, bad adaptability, add aquaculture cost and the management difficulty in later stage, easily occur the problems such as fry growth slowly, easily catches, have impact on the economic benefit of cultivation.And too much hormone of feeding, antibiotic etc, after fry grows up, have high amount of drug residual in vivo, easily cause various side effect after people are edible, there is larger potential safety hazard.
Summary of the invention
The present invention proposes a kind of indoor water body segmented ocean fish fry mating system, do not use hormone, antibiotic etc, fry survival rate is high.
Technical scheme of the present invention is achieved in that
A kind of indoor water body segmented ocean fish fry mating system, comprises the following steps:
(1) hatching of fish-egg
Hatchery water body, after precipitating, crossed by bar magnet and filtering virus disease bacterium, adds plant pH value equilibrium liquid, the fish-egg after sterilization is put into hatching water body and hatches prelarva;
(2) raising of prelarva
Hatch fish roe went out prelarva after 3 days, utilized light or food odors prelarva to be introduced nursery pond from hatchery and raised; Nursery pond water body cultivates the opening material of biological feed as prelarva in advance; In prelarva breeding process, water body adds plant pH value equilibrium liquid, and keeps nursery pond water circulation; Every 6-10 days changes a nursery pond water body, cultivates and develops into juvenile fish to larvae growth, obtains described ocean fish fry.
Further, the coprecipitation mode of step (1) described hatchery water body is natural sedimentation 3-5 days, and adopt nanometer, sunlight or mode that the two alternately irradiates to carry out disinfection in precipitation process, after precipitation, middle level and upper strata water body cross 200-250 mesh screen.
Further, the chlorine dioxide immersion 3-5min of the described fish-egg mass concentration 0.15-0.2mg/L of step (1) carries out shell sterilization.
Further, the addition of step (1) and the middle plant pH value equilibrium liquid of step (2) is that every cubic metre of water body adds 300-500mL.
Further, described plant pH value equilibrium liquid is aircraft grass roots extract or thunder godvine extract.
Further, step (1) and the middle water body of step (2) keep temperature 25-28 DEG C, dissolved oxygen 5-6mg/L, pH value 8.2-8.5, salinity 28-30 ‰.
Further, in water body, add organic manure auxiliary cultivation biological feed when step (2) fry pond water body is cultivated, the cultivation time is 5-15 days.
Further, step (2) described biological feed comprises nitrifying bacteria, plankton, diatom and wheel animalcule.
Further, lay honeycomb stone in the gradient at the bottom of pond in step (2) described nursery pond, in honeycomb stone, tracheae is set; Bar magnet is set in water body filtration process and water circulation assisted by anion ball.
Further, described every cubic metre, the nursery pond water body of step (2) only puts South America shrimp 5-6 in a suitable place to breed, removes the discarded object that fry produces.
Beneficial effect of the present invention:
The indoor water body segmented ocean fish fry mating system that the present invention proposes, whole hatching, reproductive process are carried out in indoor, are convenient to regulation and control water temperature, illumination, feeding amount, can effectively improve fry survival rate.Incubation period, by filtering fish-egg, the precipitation of hatching water body, bar magnet, can effectively remove the harmful microorganism affecting fry hatching, improve fry hatching rate; The fry stage of raising cultivates sufficient biological feed in advance and provides adapt circumstance and sufficient natural biological bait for fry growth in water body, ensure that the healthy growth of fry.Biological feed is not containing any hormone and chemical addition agent, nutritious, is the optimal opening material of larva and juvenile of just having hatched soon.Meanwhile, the water body of hatchery and nursery pond, by nanometer light or solar radiation sterilization, promotes the growth simultaneously and rapidly of fry and biological feed, guarantees that fry has sufficient food.Add plant pH value equilibrium liquid, effectively can stablize the pH value of breeding water body at 8.2-8.5, and can keep about 10-15 days constant, for the hatching of fish-egg and the growth of fry provide optimum pH value condition.Meanwhile, stable pH value condition, has preventive and therapeutic effect to disease, effectively can prevent and treat the generation of multiple fish disease.
One of the present invention indoor water body segmented ocean fish fry mating system, biological feed is cultivated in advance in water body, set up metastable circulating water body condition under field conditions (factors), the plant pH value equilibrium liquid added can stablize whole water body system pH value, temperature, pH value, dissolved oxygen and salinity that hatchery and larval rearing water body can keep relative stability, water quality keeps stable, and fry stress reaction does not occur.
Water body segmented ocean fish fry mating system of the present invention, carry out disease prevention and cure without the need to adding medicine and maintain water body environment, fry can not develop immunity to drugs, adaptability and premunition are improved, survival rate can reach about 14%, aquaculture cost and the management difficulty in later stage can be reduced, there is significant economic benefit.
