Description
Technical field:
The present invention relates to a kind of freshwater aquiculture method of marine fish.
Background technology:
The yellow Fugu of chrysanthemum (Takifugu flavidus) is the higher aquatic products of a kind of economic worth, its protein content height, fine and tender taste, nutritious, it is the important economic fish of coastal people's consumption and foreign exchange earning of foreign trade, the yellow globefish of the chrysanthemum of market sale derives from inshore fishing, owing to stimulated by high price, causes the fisherman to excessively capture excessively and gets, cause resource sharply to reduce, and individuality miniaturization gradually.
Summary of the invention:
The object of the present invention is to provide that the yellow Fugu low-salinity artificial of a kind of chrysanthemum that forms large-scale production is grown seedlings, the freshwater aquiculture method.
Technical solution of the present invention is:
The yellow Fugu low-salinity artificial of a kind of chrysanthemum is grown seedlings, the freshwater aquiculture method, its feature: comprise the following steps: successively
(1) parent fish rearing: the yellow Fugu of chrysanthemum of selecting full 2 ages.Be placed on salinity 12 ‰～8 ‰, PH and be in the pond of 16～24 ℃ of neutrality or alkalescent, water temperatures and bring up;
(2) artificial insemination and hatching: note to observe in the cultivating process, grow to V when ovum and carry out artificial insemination during the phase, and fertilized egg is placed 16～24 ℃ of water temperatures, salinity 4～7 ‰, PH is that hatch in weakly alkaline pond;
(3) seed rearing: prelarva hatches the back and moves in the fry rearing pond that 19～24 ℃ of water temperatures, PH are neutrality or alkalescent, salinity 4～6 ‰ and cultivate, and feeds with bait, and progressively salt is fallen in water and handle, and salinity is reduced to 1～3 ‰; Sending out the pool then, to enter salinity be to cultivate to young stage in 1～3 ‰ the pond, and the salinity of Chi Zhongshui is slowly reduced to 0 ‰;
(4) native pond freshwater aquiculture: will in outdoor fresh water soil pond, culture through the juvenile fish that said process is cultivated, and feed, and promptly grow up to adult fish gradually with bait.
Before parent population is carried out artificial insemination, earlier parent population injection hormone is hastened parturition.Hormone to the parent population injection is LRH-A
2And/or HCG.The method that the parent population injection is hastened parturition is: injection is carried out at twice, for the first time to female parent population injection LRH-A
215～30 μ g/Kg, male parent population exempts to annotate, injection for the second time after being separated by 4～7 hours, female parent population injection LRH-A
2150～200 μ g/Kg+HCG400～600U/Kg, milter reduces by half, and during injection, adopts the injection of pectoral fin base portion.
During parent fish rearing, the PH of water is 7.0～8.5, and bait adopts wheel animalcule or eel material, fish gruel, fish meal, or also contains the bait of vitamin and/or vegetable oil.
During incubating oosperm, place it in the incubator that is equipped with gas stone,, ovum fully cannot not dashed long-pendingly piece the inflation of gas stone.During hatching, the PH of water is 7.5～8.2.
During seed rearing, the PH of water is 7.2～8.2, with the open-mouthed bait of wheel animalcule as prelarva; Fall salt when handling, during day left and right sides, fall salt first, once fell salt in later per 1～3 day to handle, fall salt with the amplitude that reduces by 0.3～0.7 ‰ salinity at every turn in fry rearing to 7～11.Entering salinity at seed rearing is when cultivating to young stage in 1～3 ‰ the pond, adopts that big halogen worm and/or eel material, fish are rotten to be bait.
During soil pond freshwater aquiculture, bait adopts wheel animalcule or eel material, fish gruel, fish meal, or also contains the bait of vitamin and/or vegetable oil.
The inventive method uniqueness, easy to operate, the adult fish fine and tender taste that is obtained, nutritious, remarkable in economical benefits is suitable for extensive popularization.
