Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of closed zero-emission batch production Rofe fish culture side
Method.
Background technology
In aquaculture the albumen demand of aquatic livestock is apparently higher than mammal, but only about 20-30% feeds albumen
Matter is converted adult fish and obtains object, cannot largely be utilized and be present in breeding water body, the C in general breeding water body:N is less than
4.0.Excessive nitrogen will form and threaten maximum " polluted by nitrogen " for cultivating system, and leading indicator is ammonia nitrogen, nitrite, nitre
Phosphate content is exceeded, this problem is always that industrial aquaculture Tilapia mossambica is most difficult to the obstacle gone beyond.When one section of Rofe fish culture
" polluted by nitrogen " problem after period, is often encountered, the long-term exceeded, pH value of bad water colour, ammonia nitrogen, nitrite occurs and remains high
Or the cultivation problems such as variation is violent, blue-green alge grows, parasite is spread unchecked, water body is muddy, seriously polluted for a long time, disease is multiple.
It includes two kinds to solve the problems, such as this method at present mainly, first, refresh the water periodically, such as changing water 50-80% daily can be with
It solves, but it is higher to change complicated for operation not convenient and old input of water, it is that can not hold to cause huge pollute to the environment of surrounding
Continuous；Another method is to cultivate biological flocculation through common bacterium, by artificially adding organic carbonizable substance into breeding water body (such as
Molasses, glucose etc.), the carbon-nitrogen ratio (C/N) in water body is adjusted, the quantity of heterotrophicy bacteria in water body is improved, it is same using microorganism
Change inorganic nitrogen, the nitrogenous compounds such as ammonia nitrogen in water body is converted to mycoprotein, it is direct that formation can cultivate object by filter-feeding
The biological floes ingested can solve detritus and feed retention problems in breeding water body, realize the recycling of bait, play net
The effects that changing water quality, reducing quantity of exchanged water, save feed, improving cultivation object survival rate and increase yield, can solve " polluted by nitrogen "
Problem, still, this " fixed nitrogen " otherwise type biological flocculation because managing the dead further polluted-water of deposition not in place or dirt
Dye is more than seriously its load, and after the Rofe fish culture regular period, ammonia nitrogen, nitrite, nitrate content are in the same old way exceeded, and
Often crushing blow.
Therefore, it develops a kind of closed zero-emission batch production and avoids the method for breeding tilapia of " polluted by nitrogen " for a long time
It is of great significance.
Invention content
The object of the present invention is to provide a closed zero-emission batch production method for breeding tilapia, will be cultivated putting Miao Qianxian
Water body pH, total alkalinity, total hardness are adjusted to claimed range, then cultivate denitrogenation-type biological flocculation, then put seedling and be managed, warp
The Tilapia mossambica of this method cultivation grows fine, and avoids bad water body water colour caused by carbon nitrogen is unbalance, ammonia nitrogen, nitrous
The long-term exceeded, pH value of hydrochlorate remains high or changes, and violent, blue-green alge grows, parasite is spread unchecked, the long-term muddiness of water body, pollutes
Seriously, the disease cultivation problem such as multiple.
The technical scheme is that：
A kind of closed zero-emission batch production method for breeding tilapia, specifically includes following steps：
(1) water quality adjustment before seedling is put：Ensure flow rolling, on the basis of non-water flow stands dead angle, adjusts water body pH, total alkali
Degree and total hardness；
(2) inoculation of denitrogenation-type biological flocculation and cultivation：Biological denitrifier and denitrogenation-type biology wadding is added into water body for the first time
Group's culture medium, then accesses floc sedimentation kind, and denitrogenation-type biological flocculation culture medium is added into water body daily later；
(3) seedling and management are put：Rofe fry is put, feed bait daily and denitrogenation-type biological flocculation culture medium is added.
Above-mentioned denitrogenation-type biological flocculation culture medium mass percentage group becomes：Soy molasses and Sugar cane molasses 70%-
90%, Tapioca starch and wheat bran skin 8%-20%, lactic acid bacteria 1%-5%, potassium dihydrogen phosphate and calcium dihydrogen phosphate 1%-5%.
Preferably, the water source of water body is groundwater source or earth's surface allogenic water, water depth 60-80cm in step (1).
Preferably, ensure that flow rolling, blower power are provided as every cube using air blower air supply system in step (1)
5-10 watts of water body is aerated 3-5 days.
Preferably, in step (1) water body is adjusted using at least one of quick lime, calcium chloride, magnesium sulfate and sodium bicarbonate
PH value, total alkalinity and total hardness.
Preferably, water body index is in step (1)：PH is maintained at 8.0-8.2；Total alkalinity is maintained at 120-200ppm；Calcium
Ion concentration is maintained at 72-120ppm；Magnesium ion concentration is maintained at 40-100ppm；Ammonia nitrogen concentration is in 0.2ppm or less；Nitrous acid
Salinity is in 0.02ppm or less.
Preferably, the addition of biological denitrifier and denitrogenation-type biological flocculation culture medium is for the first time in step (2)
The inoculum concentration of 50ppm, floc sedimentation kind are every cubic metre of 20-30 kilograms of breeding water body.
Preferably, the amount of the denitrogenation-type biological flocculation culture medium put into daily after access floc sedimentation kind in step (2) is 10-
20ppm。
Preferably, Rofe fry specification is 3-4cm in step (3), and every cube of water body puts 80-100 tails in a suitable place to breed；Put the water before seedling
Body index is that the floc sedimentation amount generated in every liter of water body is 2-4ml, and ammonia nitrogen concentration is in 0.2ppm or less；Nitrite concentration exists
0.02ppm or less.
Preferably, feeding for bait carries out control adjustment according to the floc sedimentation amount of time and water body generation in step (3)：Put seedling
After the completion, the first meal is fed at once, bait is wheat bran or Tapioca starch, and daily ration, feeding quantity 1-2ppm is early daily, late respectively to feed once,
The control of floc sedimentation amount is every liter of water body 2-5ml；After 2 weeks, Tilapia mossambica average size 5cm or more, bait is Tilapia mossambica expanded pellet diet, is thrown
Bait amount is 3-5ppm, is respectively fed sooner or later once, and floc sedimentation amount is every liter of water body 5-8ml；After 3-4 weeks, Tilapia mossambica average size 8cm with
On, bait is Tilapia mossambica expanded pellet diet, and daily ration, feeding quantity 10-20ppm is respectively fed once sooner or later, and floc sedimentation amount is every liter of water body 6-
10ml；After 8 weeks, Tilapia mossambica average size 10cm or more, bait is Tilapia mossambica expanded pellet diet, daily ration, feeding quantity 50-100ppm, morning and evening
It respectively feeds once, the control of floc sedimentation amount is every liter of water body 8-12ml；After 12 weeks, Tilapia mossambica average size 15cm or more, bait is sieve
Non- fish expanded pellet diet, daily ration, feeding quantity 100-200ppm are respectively fed once sooner or later, and the control of floc sedimentation amount is every liter of water body 10-20ml.
Preferably, the amount for the denitrogenation-type life floc sedimentation culture medium being added daily in step (3) is 5-10ppm, is adjusted to after 8 weeks
The addition of daily denitrogenation-type biological flocculation culture medium is 20-30ppm.
Beneficial effects of the present invention are as follows：
Cultivation water pH, total alkalinity, total hardness are adjusted to claimed range putting Miao Qianxian by the present invention, then cultivate denitrogenation-type
Then biological flocculation is put seedling and is managed, the Tilapia mossambica cultivated through this method grows fine, and avoids water body due to carbon
Water colour caused by nitrogen is unbalance is bad, ammonia nitrogen, nitrite is exceeded for a long time, pH value is high or variation is violent, blue-green alge grows
The cultivation problems such as raw, parasite is spread unchecked, water body is muddy, seriously polluted for a long time, disease is multiple.
