Abstract
The invention discloses a low-salinity artificial seedling raising and fresh water aquiculture method for takifugu flavidus. The method disclosed by the invention is unique, the operation is easy, the obtained adult fish has tender meat and rich nutrition, the economic benefits are obvious, and the method is suitable for being widely popularized.
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, and its protein content is high, fine and tender taste, and is 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, and causes resource sharply to reduce, and individuality miniaturization gradually.
Summary of the invention:
Low-salinity artificial is grown seedlings, the freshwater aquiculture method to the object of the present invention is to provide a kind of yellow east of the chrysanthemum that forms large-scale production
.
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 characteristic: comprise the following steps successively;
(1) parent fish rearing: select the yellow Fugu of chrysanthemum in full 2 ages to be placed in the pond that salinity 12 ‰～8 ‰, PH are 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 get into 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.Dam fish 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 to expect, fish is rotten, 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, gas stone is inflated.Ovum fully cannot not dashed long-pendingly piece.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.Getting into 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, rotten, the fish meal of fish, or also contains the bait of vitamin and/or vegetable oil.
The inventive method is unique, and is easy to operate, the adult fish fine and tender taste that is obtained, and nutritious, remarkable in economical benefits is suitable for extensive popularization.

The yellow Fugu low-salinity artificial of a kind of chrysanthemum is grown seedlings, the freshwater aquiculture method, comprises the following steps: successively
(1) parent fish rearing: select the yellow Fugu of chrysanthemum in full 2 ages to be placed on salinity 12 ‰～8 ‰ (example 12 ‰; 10 ‰, 8 ‰), bring up in the pond of PH7.0～8.5 (example 7.0,7.4,7.7,8.0,8.2,8.5), water temperature 16～24 ℃ (16,18,20,22,24 ℃ of examples); Bait adopts wheel animalcule, and (or eel is expected, fish is rotten, fish meal; Also can contain vitamin and/or vegetable oil in the above-mentioned bait), daily ration of feeding is about 4～6% (examples 4%, 5%, 6%) of parent population weight;
(2) artificial insemination and hatching: earlier parent population injection hormone is hastened parturition, injection is carried out at twice, for the first time to female parent population injection LRH-A
215～30 μ g/Kg (example 15,20,25,30 μ g/Kg).Male parent population exempts to annotate, (example 4,5,6,7 hours) back injection for the second time in 4～7 hours of being separated by, dam fish injection LRH-A
2150～200 μ g/Kg (example 150,170,180,200 μ g/Kg)+HCG400～600U/Kg (example 400,500,600U/Kg), milter reduces by half, and during injection, adopts the injection of pectoral fin base portion.Note to observe in the cultivating process, when ovum is grown to V during the phase, carry out artificial insemination by the artificial insemination method of conventional fish; And fertilized egg placing had the incubator of gas stone, and incubator is placed in the pond that 16～24 ℃ of water temperatures (16,17,18,20,22,23,24 ℃ of examples), salinity 4～7 ‰ (example 4,5,6,7 ‰), PH are 7.5～8.2 (examples 7.5,7.8,8.0,8.2) hatches, during hatching; Gas stone is inflated; Ovum fully cannot not dashed long-pendingly piece, and through about 5～9 days, prelarva began to hatch.
