Abstract
The invention discloses a method for prompting pond- bred alosa sapidissima to spawn by ecological regulation and control. The method comprises the following steps of: in a breeding season, selecting sexually matured alosa sapidissima parent fish; stocking selected alosa sapidissima parent fish into a breeding pond for enhanced breeding, wherein the water temperature in the breeding pond is stabilized at 18 to 22 DEC G and dissolved oxygen content is kept over 6mg/L; and maintaining water flow stimulation for prompting the alosa sapidissima to spawn continuously and naturally, wherein the water flow is 3 to 8 cubic meters per hour. In the method, germ cells of the pond- bred alosa sapidissima are started and induced to mature and finally the pond-bred alosa sapidissima is prompted to spawn by adopting ecological regulation and control measures such as enhanced breeding, water temperature, dissolved oxygen content, water stimulation and the like, so that parent fish death caused by artificial oxytocin breeding is reduced and labor intensity is reduced.
Description
Technical field
The present invention relates to the fish culture technical field, especially relate to a kind of method of impelling foster America, pond hilsa herring natural spawning with ecology regulation and control.
Background technology
Occurring in nature reaches the fish of age at sexual maturity, in mating season, in case be subjected to condition element, as water level go up suddenly, water volume flow rate is accelerated and the stimulation of water temperature variation etc., and under the mutual induction of female milter, can finish the process of laying eggs, realize natural propagation.
The breed fish breeding of class of pond, owing to be subjected to the restriction of pond health attitude environmental condition, generally must be by the injection exogenous hormone, and auxilliary add effects such as necessary ecological condition such as stimulation by running water, i.e. " physiological ecological " method of combining, promote the breed fish ripe and ovulation of class parent population of pond, and mostly finish breeding by artificial insemination.The shortcoming of this fish reproduction method is: not only labour intensity is big, also causes parent population death easily.
America hilsa herring (Alosa sapidissima) belongs to a subfamily together with Chinese hilsa herring, and is very similar on form, and fine and tender taste, and delicious flavour can compare favourably with Chinese hilsa herring on mouthfeel, taste.China just introduced America hilsa herring fertilized egg from the U.S. from 2003, grew seedlings in areas such as Guangdong and Jiangsu and Zhejiang Provinces and cultured.
The America hilsa herring belongs to the river property of the tracing back fish that lay eggs, and in its long-term evolution process, has formed its intrinsic trip spawning habit of wandering from the seawater to fresh water.The America hilsa herring is moved to pond environment from natural surroundings to be cultured, huge variation has all taken place with main ecological factor such as the closely-related current of reproduction activity, nutrition, salinity, temperature, the adjustment process that the combined influence of these variations and America hilsa herring are supported environment self for adaptation pool all may cause its reproductive endocrine imbalance, causes the obstacle of hilsa herring reproduction mechanism aspect, America.
Though domestic have research unit to attempt carrying out the artificial propagation of America hilsa herring, because America hilsa herring stress reaction is strong, dried up promptly dead, artificial propagation very easily causes parent population death, and therefore, the propagation technique of America hilsa herring waits to improve further and be perfect at present.
Summary of the invention
The object of the present invention is to provide a kind of ecology regulation and control to impel the pond to support the method for America hilsa herring natural spawning, can impel America hilsa herring natural spawning, reduce the parent population death that the artificial induced spawning breeding causes, and can reduce labour intensity significantly.
Purpose of the present invention realizes by following technical scheme: a kind of method of impelling foster America, pond hilsa herring natural spawning with ecology regulation and control, it is characterized in that: in mating season, select and reach sexually matured America hilsa herring parent population, put in a suitable place to breed to cultivate in the pond and carry out reinforced cultivating, water temperature stability in the cultivation pond keeps more than the dissolved oxygen amount 6mg/L at 18～22 ℃, and keeping current stimulates, be that discharge is 3～8 cubic metres/hour, continue natural spawning to impel the America hilsa herring.
The present invention has adopted ecology regulation and control measures such as reinforced cultivating, water temperature, dissolved oxygen amount and current stimulation, start and induce the pond to support America hilsa herring reproductive cell and reach maturity and finally impel its natural spawning, reduce the parent population death that the artificial induced spawning breeding is caused, and reduced labour intensity.
Reinforced cultivating of the present invention is: with America hilsa herring parent population according to female: male=1: 1 quantity than, put in a suitable place to breed in cultivating the pond with the density of 2～3 kilograms of/cubic metre water bodys; Every day 2～3 feeds of fish body weight 2% of throwing something and feeding.
At least containing albumen in the feed of the present invention is 45～48%, and vitamin E is 0.4～0.8%, and unsaturated fatty acid is 2～4%.
As one embodiment of the present invention, described cultivation pond is that area is 200～250 square metres a cement pit, the depth of water is 110～130cm, the bottom surface, pond is the edge to central authorities' concavity gradually, the center is provided with drain inlet at the bottom of the pond, the corresponding drainage outlet that is provided with drain inlet is provided with water inlet cultivating pool side, and the water when water (flow) direction makes water into along the tangential direction of pool wall in the pond can rotate.
Of the present invention to keep that current stimulate be that discharge is to fill whole cultivation pond in 2 days, and promptly discharge is 5～6 cubic metres/hour.
The present invention strengthens injection flow and is and filled whole cultivation pond in 1 day when finding to have America hilsa herring parent population to chase mutually, and promptly discharge is 10～12 cubic metres/hour.Under the stimulation of water temperature, current etc., America hilsa herring parent population can be successively, continue natural spawning.
The present invention increases the water body dissolved oxygen amount and adopts aerator, and the rotation direction of aerator is consistent with the water inlet direction.Concentrate to pond central authorities so that drive the excreta of cultivating in the pond, help dirt and discharge from drain inlet is concentrated.
The present invention is provided with egg-collecting box at drainage outlet, and fertilized egg is collected, and fertilized egg is inserted in the incubator hatch again.
The present invention is cultivating top, pond covering double-layer plastic film, and adds a cover double-deck black sunshade net, and double-layer plastic film plays insulation effect, and double-deck black sunshade netting gear has dimming function.
The present invention is provided for preventing the anti-facility of escaping of America hilsa herring parent population escape in described drain inlet; Be provided with gap at described drainage outlet.
Compared with prior art, the present invention has following significant effect:
The present invention has adopted and the closely-related ecology regulation and control measure of America hilsa herring reproduction activity, guaranteed the normal reproduction mechanism of America hilsa herring, start and induce the pond to support America hilsa herring reproductive cell and reach maturity and finally impel its natural spawning, reduced the parent population death that the artificial induced spawning breeding is caused, and reduced labour intensity, the further perfect propagation technique of America hilsa herring has been started the trip property fish of wandering and has been supported the new situation of breeding under the condition in the pond.
