Description

The nearly red Culter master of a kind of black tail supports the pool with the method for pond from propagating and cultivating winter sheet fingerling
Technical field
The invention belongs to technical field of aquaculture, be specifically related to the nearly red Culter master of a kind of black tail and support the pool with the method for pond from propagating and cultivating winter sheet fingerling.
Background technology
The nearly red Culter of black tail (AncherythroculternigrocaudaYihetWu) is subordinate to Cyprinidae, Culter subfamily, nearly red Culter genus, is the Endemic fish being distributed in Hydro-electricity, has higher economic worth and nutritive value.In current production, the nearly red Culter nursery of black tail many employings manual injection hastens parturition, and the method for winter sheet fingerling is cultivated in single pond, and in actual artificial induced spawning process, and it is large that fisherman draws in the net the labour intensity such as operation, parent postpartum often lethality up to 100%.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly is carrying out while pond adult fish master supports, and batch solves the problem of the nearly red Culter seedling self-fertile self-sufficiency of black tail, does not need to carry out manual injection and hastens parturition and carry out leading the foster pool with the method for pond from propagating and cultivating winter sheet fingerling.
The present invention solves the problems of the technologies described above by the following technical programs:
The nearly red Culter master of black tail supports the pool with the method for pond from propagating and cultivating winter sheet fingerling, adopts following processing step:
(1), pond prepares: before fingerling stocking, to clean up the pond sterilization with quicklime 75 125kg/ mu, after execute fertilizer 100 150kg/ mu through fermenting;
(2), fingerling stocking: put the nearly red Culter of two black tails in age in winter in a suitable place to breed, breeding density 1,000 1200 tails/mu;
(3), feedstuff feeding: cultivation overall process is thrown something and fed 1.5 ~ 2mm Culter class special swelling granular mixed feed, adopt the special batch of Culter class of crude protein content 36% 3-5 month, adopt the special batch of Culter class of crude protein content 32% 6-11 month, day throws something and feeds 2 ~ 3 times, eat up in each 1 hour, it is 3 5% of fish body weight that day throws the amount of raising;
(4), daily management: 1-12 month, regulation and control water quality: control water transparency 30 40cm, the ammonia-nitrogen content in water body lower than the content of nitrite in 0.10mg/L, water body lower than 0.01mg/L, the pH value 7.0 8.5 of water body.
In order to obtain better technique effect, in step (1), select pond area 3 10 mu, dark 1.8 2.5m in pond, pond east-west direction; In step (2), two black tails in age in winter nearly red Culter specification 18 22cm, weight 75 125g; Every mu of collocation silver carp Variegated 50 tail, specification 0.5kg/ tail; Before putting in a suitable place to breed, the salt solution of the nearly red Culter mass fraction 3 5% of two black tails in age in winter is embathed 5 10 minutes, or with povidone iodine dipping 20 30 minutes; In step (4), 5-7 month, arrange plant floating bed: place the phytoplankton accounting for 10 20% pond areas, frame becomes square or triangle, water body controls transparency 50 60cm, and regularly the new water of filling, promotes parent's gonad development and natural spawning, in 6-7 month, throw something and feed by every mu of every ten thousand tail fries 1.5 2 kilograms of soya bean defibrinations; In 8-11 month, to throw something and feed the special batch of 0.5 1mm small particle diameter Culter class by 5 8% of fingerling weight.
It is short that the nearly red Culter of black tail cultivates the time relative " four large Chinese carps ", and winter sheet specification is between 7 11cm then to cause it, and the winter sheet fingerling of this specification, through the cultivation of one-year age, is difficult to reach listing specification (more than 0.5kg/ tail) then.Therefore, in production, many employings are bred as pattern for 2 years and cultivate the nearly red Culter fingerling of large gauge two black tail in age in winter, put the large size fingerling of 15 18cm in a suitable place to breed to reach specification of going on the market then.The two black tail female milter of nearly red Culter in age in winter sexual maturity, the adult fish culture pattern that the nearly red Culter of black tail can be utilized to put large size fingerling in a suitable place to breed has reached sexually matured biological property with it, produces winter sheet fingerling with pond Ecology nursery.The nearly red Culter repoductive time of black tail is in 5-7 month, its peak value is in June, be put the nearly red Culter large size fingerling of two black tails in age in winter in a suitable place to breed with the density of 1,000 1200 tails/mu in the Cultivated water of 3 10 mu at area, be equipped with the measures such as induced spawning, ecology regulation and control, standardized production simultaneously, after 1 year, the nearly red Culter of black tail becomes more than fish crop 500kg/ mu, more than commercial specification 0.60kg/ tail, more than winter sheet fingerling output 100kg/ mu, specification 20 30g/ tail.
Compared with the prior art the present invention, has the following advantages:
1, the present invention carries out adult fish master and supports pattern and Ecology nursery combines, thus provides the nearly red Culter master of a kind of black tail to support the pool with the method for pond from propagating and cultivating winter sheet fingerling, the method can ensure main form fish crop while, winter sheet fingerling can be bred as in batches.
2, pass through with the new method of black tail nearly red Culter in pond from numerous self-fertile, solve the problem that parent's lethality in the nearly red Culter artificial induced spawning process of black tail is high, not only save hormone expenses, and have and do not damage the nearly red Culter parent of black tail, alleviate workload, save oxytocic hormone expense, regulation and control pond culture environment, promote the advantages such as aquatic product quality.
