Abstract
The invention belongs to the fish hatching field, and particularly relates to a hatching method for fries of scaphes macrolepis. The hatching method for the fries of scaphes macrolepis comprises the following steps: (1) culturing under the condition which meets the biological characteristics of parent fish; (2) at night during a wintering period, additionally arranging an incandescent lamp light source beside a fish pond to prolong the illumination time for parent fish; (3) during the reproduction period, collecting the parent fishes, raising a water inlet, doubling water inlet amount, and stimulating breeding needs of brood fish; (4) selecting healthy and mature female and male parent fishes and putting the parent fishes into the fish pond with a sliver-sand egg picker to naturally breed the parent fishes; (5) separating the female and the male for the naturally bred parent fishes, transferring the parent fishes into the fish pond with a relatively low temperature to carry out strengthened cultivation for one month; and (6) injecting a parent fish ripener into the parent fishes subjected to the strengthened cultivation to carry out artificial reproduction.
Description
Technical field
The invention belongs to Fish hatcheries field, be specifically related to the fry hatching method of a kind of many squamas shovel jaw fish.
Background technology
Many squamas shovel jaw fish length, slightly flat-sided, the back of the body slightly swells, abdominal part circle.Short, to kiss blunt, mouth is the next, and transverse fissure, bicker extends the lateral margin of an outside of belly.Mandibular border has sharp keen cutin；Palpus 2 is right, and the upper jaw must be superfine little, and bicker must be also very short.Dorsal fin is without hard thorn, and outer rim is recessed slightly within.Chest scale is less, is embedded in subcutaneous.Body back of the body pitchy, abdominal part is greyish white.The base portion of each scale in side has crescent black speck, dorsal fin and tail fin grey black, other each fin lark, and outer rim is golden yellow, and dorsal fin and anal fin have a salmon pink speckle.
The breeding of current many squamas shovel jaw fish mostly adopts natural propagation, or adopt Two-dose schedule artificial propagation, the part but both propagation methods all come with some shortcomings: not only parent fish ovulation amount is few for the former, and incubation rate is extremely low, the latter's ovulation amount is more, but incubation rate is low, and milter row's essence time bad control.
Summary of the invention
Goal of the invention: the present invention is directed to above-mentioned prior art Problems existing and make improvement, namely the invention discloses the fry hatching method of a kind of many squamas shovel jaw fish.
Technical scheme: the fry hatching method of a kind of many squamas shovel jaw fish, including:
(1) cultivate when meeting parent fish biological characteristics:
(11) the same pond of male and female, promotes gonad development；
(12) flowing water culture；
(2) at the night of Wintering Period, in fishpond, the other incandescent light source that increases increases parent fish light application time；
(3) in idiophase, being drawn in together by parent fish, water inlet is raised, and inflow is double, excites kind of a fish breeding demand；
(4) selecting the male and female parent fish of healthy mature to be placed on device has fine sand to adopt the fishpond of egg apparatus, so as to natural propagation；
(5) by the parent fish after natural propagation, male and female are separated, and turn fishpond supported water temperature is relatively low carries out a month intensified education by a definite date；
(6) parent fish ripener, artificial propagation are injected again to the parent fish after intensified education.
Further, described parent fish ripener is luteotropin releasing hormone d-ala analog, and the consumption of described luteotropin releasing hormone d-ala analog is 10ug/KG.
Further, described parent fish ripener is luteotropin releasing hormone d-ala analog and chorionic-gonadotropin hormone, and the consumption of described luteotropin releasing hormone d-ala analog is 10ug/KG, and the consumption of described chorionic-gonadotropin hormone is 500IU/ tail.
Further, described parent fish ripener is luteotropin releasing hormone d-ala analog, chorionic-gonadotropin hormone and maleic acid DOM, the consumption of described luteotropin releasing hormone d-ala analog is 10ug/KG, the consumption of described chorionic-gonadotropin hormone is 500IU/ tail, and the consumption of described maleic acid DOM is 2mg/KG.
Beneficial effect: the fry hatching method of a kind of many squamas disclosed by the invention shovel jaw fish has the advantages that
1. the illumination that winter increases makes parent fish sexual maturity time advance, provides grace time for nursery stage by stage later；
2 utilize natural propagation parent fish gonad to be able to normal development, raun birth canal is able to natural thinning and passes to and lay eggs less and halfway feature, low temperature point male and female intensified education is turned after one month after natural propagation, transfer artificial propagation again to, both the using dosage of oxytocic drug and the damage to parent fish had been decreased, avoid the too fast drawback natural spawning oligospermia with milter oligospermia of parent fish development of fertilized ova that Two-dose schedule causes simultaneously, directly act on water body, relatively divide and spread, the motility of sperm time is short, and Two-dose schedule oxytocin can cause squeezing not out when milter seminal fluid discharges in advance or hastens parturition, can increase the milter gonad development time after improvement, seminal fluid is more.Improve the utilization rate natural spawning general utilization of fish roe in raun body 30%, Two-dose schedule is 50%, and after improvement, utilization rate is 75～80%, also improves the fertility rate and hatchability of artificial propagation.
Detailed description of the invention:
Below the specific embodiment of the present invention is described in detail.
Specific embodiment 1
A kind of fry hatching method of many squamas shovel jaw fish, including:
(1) cultivate when meeting parent fish biological characteristics:
(11) the same pond of male and female, promotes gonad development；
(12) flowing water culture；
(2) at the night of Wintering Period, in fishpond, the other incandescent light source that increases increases parent fish light application time；
(3) in idiophase, being drawn in together by parent fish, water inlet is raised, and inflow is double, excites kind of a fish breeding demand；
(4) selecting the male and female parent fish of healthy mature to be placed on device has fine sand to adopt the fishpond of egg apparatus, so as to natural propagation；
(5) by the parent fish after natural propagation, male and female are separated, and turn fishpond supported water temperature is relatively low carries out a month intensified education by a definite date；
(6) parent fish ripener, artificial propagation are injected again to the parent fish after intensified education.
Further, parent fish ripener is luteotropin releasing hormone d-ala analog, and the consumption of luteotropin releasing hormone d-ala analog is 10ug/KG.
