Abstract
The invention discloses a method for breeding the white croaker. The method comprises the steps of culture pond selecting, parent fish selecting, spawning, fry breeding, artificial promoting and disease preventing and treating, the survival rate of the white croaker is increased, and the bred fingerling is large, high in growth performance, robust in physique and high in disease resistance.
Description
Technical field
The present invention relates to a kind of cultural method of aquatic products, particularly the cultural method of a kind of white Chinese croaker.
Background technology
Present stage, aquatic products have become the one in people's diet, the Typical Representative thing that its Mesichthyes is aquatic products, but because the cultural method of existing fish is limited, make cultivation fish inferior quality out, especially for some ocean fishes, its poor growth, and meat is comfortable, peculiar smell increases the weight of, and adopts existing cultural method simultaneously, not only the little meat of body is few for fish, and the resistance against diseases of fish declines, life-span is lower, and easily dead, such cultural method can not meet the existing requirement of people.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the cultural method of a kind of white Chinese croaker, can make white Chinese croaker survival rate high, and cultivation fingerling is out individual greatly, growth performance is high, physique is healthy and strong, resistance against diseases is strong.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the cultural method of a kind of white Chinese croaker is provided, and its concrete grammar is as follows:
(1), culturing pool is selected: culturing pool comprises: freshwater aquiculture pond and seawater-culture pond, it is 30-40m that area is selected in described freshwater aquiculture
2, the dark 1.5-2mm in pond, having thickness is the pond of 8-12mm mud, it is 20-30m that described seawater-culture pond is selected area
2, the dark 2-3mm in pond, having thickness is the pond of 8-12 mud;
(2), parent population is selected and lays eggs: selecting body weight is that 300 grams of above female milters are thrown in into freshwater aquiculture pond, regularly in pond, throws in bait, through within 25-20 days, laying eggs voluntarily, breed, after laying eggs, in time parent population is caught out;
(3), the cultivation of growing seedlings: fish-egg was emerged after 2-5 days, well doneization of throwing something and feeding granular bait for fish, day feeding volume is the 8-10% of fish body weight, throw something and feed after 10-15 days, well doneization of throwing something and feeding fritter shape bait, a day injected volume is the 20-30% of fish body weight, throw something and feed after 16-24 days, the tiny trash fish of throwing something and feeding, a day injected volume is the 40-50% of fish body weight, water temperature all remains on 8-15 degree during this time.。
(4), artificial ripening: the white Chinese croaker after cultivating is put in to seawater-culture pond to be stimulated, and impels the gonad maturity of white Chinese croaker, obtains very large, ripe white Chinese croaker.
(5), disease prevention and cure: every 1 time-of-week, carry out disinfection to throwing in quicklime in freshwater aquiculture pond and seawater-culture pond.
In a preferred embodiment of the present invention, the mode that keeps water temperature in described step (3) is to adopt the mode of building cool canopy and warming measure being set.
In a preferred embodiment of the present invention, the salinity of described seawater-culture pond is 7-12%, and the salinity in described freshwater aquiculture pond is 2-3%.
Beneficial effect of the present invention: the present invention is by the selection of culturing pool, the selection of parent population and the cultivation of laying eggs, growing seedlings, manually impel and the measure of disease prevention and cure, make white Chinese croaker survival rate high, and cultivation fingerling is out individual greatly, growth performance is high, physique is healthy and strong, resistance against diseases is strong.
Embodiment
The present invention will be described in detail below, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
In an embodiment of the present invention, the cultural method of a kind of white Chinese croaker, its concrete grammar is as follows:
(1), culturing pool is selected: culturing pool comprises: freshwater aquiculture pond and seawater-culture pond, it is 30-40m that area is selected in described freshwater aquiculture
2, the dark 1.5-2mm in pond, having thickness is the pond of 8-12mm mud, it is 20-30m that described seawater-culture pond is selected area
2, the dark 2-3mm in pond, having thickness is the pond of 8-12 mud;
(2), parent population is selected and lays eggs: selecting body weight is that 300 grams of above female milters are thrown in into freshwater aquiculture pond, regularly in pond, throws in bait, through within 25-20 days, laying eggs voluntarily, breed, after laying eggs, in time parent population is caught out;
(3), the cultivation of growing seedlings: fish-egg was emerged after 2-5 days, well doneization of throwing something and feeding granular bait for fish, day feeding volume is the 8-10% of fish body weight, throw something and feed after 10-15 days, well doneization of throwing something and feeding fritter shape bait, a day injected volume is the 20-30% of fish body weight, throw something and feed after 16-24 days, the tiny trash fish of throwing something and feeding, a day injected volume is the 40-50% of fish body weight, water temperature all remains on 8-15 degree during this time.。
(4), artificial ripening: the white Chinese croaker after cultivating is put in to seawater-culture pond to be stimulated, and impels the gonad maturity of white Chinese croaker, obtains very large, ripe white Chinese croaker.
(5), disease prevention and cure: every 1 time-of-week, carry out disinfection to throwing in quicklime in freshwater aquiculture pond and seawater-culture pond.
Be different from prior art, adopt freshwater aquiculture pond and seawater-culture pond, can promote the growth of white Chinese croaker, increase the volume of white Chinese croaker; Adopt 300 grams of above female milters, volume is large, quality better again, and the kind of the ovum of institute's output also improves thereupon; Then adopt distinctive seedling raising manners and artificial ripening, can make sashimi (raw fish) long faster, better; Finally adopt quicklime to carry out disinfection to water quality, can strengthen the resistance against diseases of fish, improve viability.
In another preferred embodiment of the present invention, the mode that keeps water temperature in described step (3) is to adopt the mode of building cool canopy and warming measure being set.
Further illustrate, summer, temperature is higher, adopts the mode of building cool canopy, can reduce temperature around, thereby keeps water temperature; And winter, temperature is lower, adopt the mode that warming measure is set, can keep water temperature.
In another preferred embodiment of the present invention, the salinity of described seawater-culture pond is 7-12%, and the salinity in described freshwater aquiculture pond is 2-3%.
Further illustrate, adopting the salinity in freshwater aquiculture pond is 2-3%, after the salinity of seawater-culture pond is 7-12%, when white Chinese croaker is put into seawater-culture pond from freshwater aquiculture pond, can fully stimulate white Chinese croaker, impel the gonad maturity of white Chinese croaker, thereby accelerate the growth and development of white Chinese croaker.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in the present invention.
