Description

A kind of Tilapia mossambica fingerling high-yield cultivation method
Technical field
The present invention relates to method for cultivation of fish, be specially a kind of Tilapia mossambica fingerling high-yield cultivation method.
Background technology
Tilapia mossambica is to originate in the torrid zone, semi-tropical warm water fishes.Because its feeding habits are wide, premunition is strong, it is fast to grow up, fertility is strong, environmental suitability is strong, it is the aquaculture kind that FAO (Food and Agriculture Organization of the United Nation) is recommended to the whole world, and its output is only second to the main cultured fishes in the world---carp, occupies second.Along with the decline of global marine fishing fishery resources, the international market is increasing to the demand of aquaculture products.In numerous breed article; Tilapia mossambica is thick with its meat, spur is few, be convenient to processing and antistaling; And contain multiple unsaturated fatty acid, fine and tender taste, slightly pleasantly sweet, suit the taste of both old and young, meet the human advantages such as requirement of pursuing healthy food; Become generally acknowledged healthy food, be called as " fish of 21 century " in the world.
Tilapia mossambica is one of leading aquaculture kind of Ministry of Agriculture's issue, in the aquaculture industry, has critical role, and the improvement of each technology all has a far reaching influence.In northern China; Tilapia mossambica also is the aquatic products that liked by the consumer; Because the restriction of natural conditions must put large size fingerling in a suitable place to breed northern Tilapia mossambica and just can form, so need be carried out nurture of fish fingerlings winter; And in order to save Winter heat supply resource in short supply, improving per unit area yield is the good method of dealing with problems.
Summary of the invention
The present invention creates suitable growing environment according to the biological property of Tilapia mossambica, according to its nutritional need the bait of comprehensive nutrition is provided, and cooperates other technical measures to form a Tilapia mossambica fingerling high-yield cultivation method.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of Tilapia mossambica fingerling high-yield cultivation method comprises following operating procedure:
1. cultivating condition: the native pond that the suitable high-density breeding of surviving the winter is provided;
2. water quality control: keep the water body dissolved oxygen more than 3mg/L, water temperature is controlled at 20~28 ℃;
3. cultivation density: throw in an amount of seed, guarantee to produce fingerling more than 40000kg/ mu;
4. feedstuff feeding: the feed of rationally throwing something and feeding guarantees to culture fish and grows up healthy and sound fast;
5. disease prevention and cure: regularly throw something and feed pharmaceutical chemistry, replenishing vitamins, prevent and treat fish disease, improve fish body resistance;
6. safety management: guarantee that equipment operation is normal, particularly aerator can not be out of service.
1. said step is: bottom material of pond for breeding is soil property, and is non-leakage, and area is at 2~2.5 mu, and the depth of water is provided with aerator at 2.6-3.0m, is equipped with generator, bait throwing in machine.
Said step is 1. at northern area, and passing the winter to possess the GEOTHERMAL WATER resource, and builds heat preservation greenhouse.
2. said step do, changes water 10-30cm every day, got rid of bottom food-residue, ight soil once with silt remover in every month, and per 10 days according to 0.1-0.2g/m 3Concentration, splash C5H6Br2N2O2 once.
3. said step is: mu is put specification 5cm fry 120,000 tails.
Said step specification 5cm fry is 3. concentrated and cultivates for after buying the 1-3cm fry, to 5cm, puts into pond culture.
4. said step is: adopt the bait throwing in machine; The fingerling specification is thrown something and fed 6 times every day before the 50g/ tail, throws something and feeds every day afterwards 4 times, throws something and feeds according to fish body weight 5% before the 50g/ tail; Reduce to fish body weight 3% behind the 50g/ tail gradually; Back inspection half an hour of throwing something and feeding remains the material situation, then reduces feeding volume if any residue, and aerator does not stop when throwing something and feeding.
5. said step is: fed a pharmaceutical chemistry in per 7 days, and added the allicin 350g/ ton feed, the fish that contain mass percent 25% and use vitamin C to use vitamin E to be 200g/ ton feed as 800g/ ton feed, fish.
6. said step is: under this high-yield mode, arrange special messenger 24 hours on duty, will in time find in guaranteeing to have a power failure 10 minutes, and starter-generator, must open whole aerators in 30 minutes.
The invention has the beneficial effects as follows: according to the extremely strong adaptive capacity of Tilapia mossambica, create growing environment, and use for reference the industrial aquaculture technology near the limit; Sufficient oxygen is provided; In time handle dirts such as residual bait, ight soil, strengthen throwing something and feeding management, guarantee that feed nutrition is balanced; Refresh the water periodically, sterilize and carry out prevention from suffering from the diseases, to reach the purpose that improves cultivation density.Per mu yield reaches more than the 40000kg, and this method mainly is applicable to native pond high-density breeding.
