Abstract
The invention relates to an artificial cultivation and domestication method of American shad fry and fingerlings, which optimizes the soil pond artificial cultivation steps through the measures of controlling water quality and baits in a soil pond, putting the fry in the pond as early as possible, carrying out special treatment on the baits for domestication and feeding and the like, thereby avoiding the death of American shads under stress to the maximum extent, greatly reducing the labor intensity, significantly improving the growth speed and having the advantages of simple operation, low cost, good domestication fry and fingerlings and the like. The artificial cultivation and domestication method comprises the following four steps: 1, biological cultivation and incubation management ofthe baits in the pond; 2, feeding with zooplankton; 3, feeding with special feeds, which is divided into two rearing stages: the feeding with the zooplankton is reduced and the feeding with the special feeds is simultaneously carried out in the first stage and only the feeding with the special feeds is carried out in the second stage; and 4, feeding with artificial expanded feeds, which is also divided into two rearing stages: the feeding with the special feeds is reduced and the feeding with the artificial expanded feeds is simultaneously carried out in the first stage and only the feeding with the artificial expanded feeds is carried out in the second stage.
Description
Technical field
The present invention relates to a kind of artificial cultivation and domestication method of American shad fry and fingerlings, belong to the fish culture technical field.
Background technology
The America hilsa herring, formal name used at school Alosa sapidissima, English name American shad has another name called U.S. hilsa herring, clupeidae, Alosa.The America hilsa herring is favored by the consumer deeply with its fine and tender taste, plump fertile and celebrated, economic worth is high.
Because the fertilized egg of America hilsa herring is introduced a fine variety the breakthrough of hatching, breed and artificial propagation techniques, demand forming a cover fingerlings artificial culturing urgently and raise and train technology.American shad seedling initial feeding early, basically get final product opening after about 20 ℃ of water temperatures are descended membrane 2-3 days, and young juvenile fish stress reaction is strong, artificial improper operation can cause large batch of death, so the seed rearing technology of other fish also is not suitable for cultivation America hilsa herring.At present, the American shad seedling that indoor little cement pit that adopts or cement pit are established net cage is cultivated, changeing the food domestication then utilizes and beats as its signal or utilize light to tame and docile food at night of ingesting, exist because of subenvironment stress not cause that America hilsa herring growth is slow with bait abundance good enough, transportation shift difficulty greatly and because of the America hilsa herring to the water quality requirement height, soil pick-up and increase drawback such as labour intensity again and again.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of new fingerlings artificial culturing domesticating method is provided, the regulation and control of water quality bait, fry by native pond descend the pool, specially treated bait to tame and docile stimulation optimization soil pond artificial culture steps such as food early, that has avoided the America hilsa herring to greatest extent stress be dead, not only greatly reduces labour intensity and also significantly improved growth rate.
According to technical scheme provided by the invention, a kind of artificial cultivation and domestication method of American shad fry and fingerlings is characterized in that comprising following four steps:
1, the pond food organisms are cultivated and hatching management
Just the membrane prelarva is raised in hatching pail, and should in time reduce water velocity and reduce oxygenation intensity this moment, and suitably add wheel animalcule.
The special-purpose Tu Chi that cultivates through the clean up the pond sterilization and tanning by the sun 6-10 days of 120Kg/ mu quicklime, is filled to depth of water 0.8-1.0m, the fertilizer 20Kg/ mu of dispensing fermentation.
The pool, the 2-3 world should be 15-18 days after the water filling of pond this moment behind the fry membrane.
2, feeding with zooplankton
The following pool is after 15 days, throws something and feeds with the red worm after the sterilization and cultivates in the native pond in special use, keeps 10～15/ml of zooplankton in the pond.
3, special feedstuff feeding
Be divided into two raising stages, the phase I gradually reduces plankton, adds simultaneously and feeds special feed, and the time of throwing something and feeding is 7～10 days, and every day at the upper and lower noon respectively throws something and feeds 1 time.The second stage special feed of only throwing something and feeding, the time of throwing something and feeding is 10～15 days, every day at the upper and lower noon respectively throws something and feeds 1 time.
Special feed be the weight ratio with eel feed and water be 9: 1～8: 1 formulated.
4, artificial expanded pellet diet is thrown something and fed
Be divided into two raising stages, the phase I gradually reduces special feed, adds simultaneously and feeds artificial expanded pellet diet, and the time of throwing something and feeding is 5～7 days, and every day at the upper and lower noon respectively throws something and feeds 1 time.The second stage artificial expanded pellet diet of only throwing something and feeding, every day at the upper and lower noon respectively throws something and feeds 1 time.
Compared with the prior art the present invention has following beneficial effect:
1, advantage such as easy and simple to handle, with low cost, domestication seed quality better is arranged; The method that combines according to ecological principle and America hilsa herring early growth and development characteristic, the 2nd day bait of promptly throwing something and feeding behind membrane, the mistaken ideas that just begun bait throwing in after having avoided yolk sac to disappear, guaranteed the survival rate of fry, having solved effectively grows in the domestication process reaches the problem that cement pit is cultivated the frequent soil pick-up of palpus slowly.
2, the present invention successfully cultivates the America hilsa herring domestication becomes and is suitable for that the pond is propagated artificially, premunition strong, the fingerling of fast growth, for the domestications of other fish identical with physiological conditions with America hilsa herring feeding habits provides gross data and practical experience.
