Description
Technical field
The present invention relates to aquaculture technical field, especially a kind of Pangasius sutchi low salinity stocking method.
Background technology
Pangasius sutchi, scientific name Su Shi circle abdomen fish awns (Pangasius hypophthalmus), also known as Ba Dingyu are under the jurisdiction of
Os osseum guiding principle, Silurformes, Yu Mang sections, circle abdomen fish awns genus, is the Important Economic fish for being grown in the Southeast Asia Mekong River valley, growth
Soon, disease resistance is strong, lower oxygen concentration resistance, high without thorn, nutritive value between flesh, has black, white and grey three kinds of body colours, ornamental value is high, juvenile fish
It is often sold as ornamental fish, belongs to middle-size and small-size economic freshwater fish, because of business and the similar reason of shape, 2005 in China
When Southern Coast area is promoted, it is referred to as Pangasius sutchi.The fish is more in the southern province cultivation such as Guangdong, Guangxi, Hainan at present,
It is the preferable freshwater aquiculture kind in China.
The main method of domestic cultivation Pangasius sutchi has cage culture, Pond culture, mixed breeding, reservoir cultivation, rice field at present
Cultivation and warm flow water cultivation, and the Pangasius sutchi raised using modes such as cage culture, pond polycultures, meat are general, slightly
Bilgy odour, growth are not rapid enough and liable to illness.
Therefore, find that a kind of growth of Pangasius sutchi is rapid, and illness rate is low, and gained Pangasius sutchi is Fresh ＆ Tender in Texture in good taste, nothing
The Pangasius sutchi cultural method of bilgy odour is the task of top priority.
Invention content
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of Pangasius sutchi low salinity stocking
Method is achieved particular by following technical scheme：
A kind of Pangasius sutchi low salinity stocking method, includes the following steps：
(1) pond prepares：Prepare aquaculture pond, depth 0.8-2m, intake-outlet sets fence；
(2) pond pre-processes：Aquaculture pond clean up the pond after disinfection, water is poured into aquaculture pond, regulating reservoir salinity water exists
5‰-6‰；
(3) fertilising training water：The muck that decomposed fermentation is applied to aquaculture pond cultivates food organisms；
(4) seedling is put：According to 150-200 tails/m2Breeding density launch fry, fed after putting seedling, it is 2-8 times daily.
(5) the fingerling stage：Water salinity is improved to 7 ‰ -9 ‰, breeding density is adjusted to 100-150 tails/m2；
(6) adult fish stage：Using monoculture mode, water salinity is improved to 9-11 ‰, cultivation density 2500-3500 tails/
Mu, cultivation 4-6 months, makes average weight at 1 kilogram or more, you can capture.
Preferably, the aquaculture pond of the step (1), area is 100m2, depth is 1.2m.The aquaculture pond of this specification is suitable
Pangasius sutchi fry growth.
Preferably, the step (2), aquaculture pond is poured by water, is to mix seawater and river water to pour into aquaculture pond.By seawater
It is mixed with river water, mixed water can be made to have certain salinity and microorganism bait, and salt need not artificially be added to adjust
Salinity is saved, is further reduced the cost.
Preferably, the step (4) is to carry out feeding after being mixed with the feed of long-snout catfish with sea eel.Further preferably, eel
The mixed proportion of fish meal and long-snout catfish feed is 1:1, daily ration of feeding is the 6%-8% of full pond fish weight.Eel feed and length
Wen Catfish feeds are easier to obtain, and relatively Pangasius sutchi are suitble to eat after the two is mixed, are thrown according to the 6%-8% of pond fish weight
Bait can effectively reduce bait surplus.
Preferably, the step (5) is to use 200m2Aquaculture pond raised.The aquaculture pond of this specification is suitable for fingerling
The Pangasius sutchi in stage is grown.
Preferably, the step (6), is to carry out feeding with Tilapia mossambica man-made feeds.Tilapia mossambica man-made feeds are easier to obtain,
Also the daily need of Pangasius sutchi can be substantially met.
Preferably, the step (6) is raised using 3-8 mus of large-scale aquaculture pond.The aquaculture pond of this specification is suitable
The Pangasius sutchi of adult fish stage is grown.
Preferably, in the breeding process, probiotics regulating water quality is taken, and controls 25-30 DEG C, pH7-9 of aquaculture pond water temperature,
Simultaneously pond is handled using potassium hydrogen persulfate reconciliation powder.The probiotics is lactic acid bacteria, Bifidobacterium, bacillus subtilis by 1:
2:1 ratio mixes.Probiotics can promote the growth and development of Pangasius sutchi, and the harmful bacteria in aquaculture pond is inhibited to breed；
Potassium hydrogen persulfate reconciliation powder can fully improve aquaculture pond substrate.
Compared with prior art, the technique effect of the invention is embodied in：
The method of the present invention cultivates Pangasius sutchi using low salinity stocking pond water, and in the fish of Pangasius sutchi
Seedling, fingerling, adult fish stage adjust aquaculture pond water to different salinity, and the Pangasius sutchi in each stage is made to have preferable growth speed
Degree, the Pangasius sutchi of the method according to the invention cultivation, growth speed are faster 30- than the Pangasius sutchi with freshwater aquiculture
50%, and illness rate is low, fine and tender taste, no bilgy odour.
