Abstract
The invention discloses a method for identifying the sexual maturity of parent fish of schizothorax. The method is characterized by comprising the following steps of fishing healthy male and female parent fish reaching sexual maturity from a parent fish culture pond in a mating season of the schizothorax; scooping up the fish in a pre-prepared container or a fish clamp; watching the rostral side of the head part of the fish through naked eyes, and determining that fish with bead stars is male fish and the fish without the bead stars is female fish. By adopting the method for checking the caudal peduncle of the male and female parent fish by adopting a magnifying lens, the method has the advantages that distinguishing on fish sexual maturity is accurate and fast, the fish is not damaged, the operation is convenient, and the method can be easily mastered.
Description
Technical field
The present invention relates to preparation method technical field, more particularly to a kind of discriminating schizothoracin parent population sexal maturity
The method of degree.
Background technology
Judging fish male and female parent population sexal maturity situation, usually in the mating period of the fish, will be female
Fish fish body is upward, slightly dew face, and both sides are clearly visible ovary profile, and belly is gently pressed with hand, soft rich
It is flexible；Milter " pearl star " substantially, and has very strong harsh feeling, and fish body belly upwards, gently presses abdomen
Portion both sides, have milky thick seminal fluid to flow out, and meet water and do not scatter rapidly person preferably；Take digging simultaneously
Ovum inspection and ultrasound diagnosis method further accurately judge that the maturity of raun is most preferably hastened parturition to obtain
Effect.There is problems with above method：1st, easily judge by accident, particularly raun, if in parent fish rearing
Stage, feed nutritive value is good, and the coefficient of condition of fish is good, and body fat content is high, even sexal maturity
Good parent population, ovary profile is unclear；And the bad parent population of sexal maturity, fish body belly is equally soft to be rich in
Elasticity.Therefore, often the bad parent population of sexal maturity is hastened parturition as the good parent population of sexal maturity, and
The good parent population of sexal maturity is not hastened parturition again, the success rate for causing spawning effect difference influence to be hastened parturition；2nd, judge
It is inaccurate：" the pearl star " of particularly milter will experience generation, the process for developing and coming off, whole
During, except less obvious when just playing gesture, other when until coming off before be all it is obvious,
And harsh feeling has in the whole evolution of " pearl star ", to say " very strong harsh feeling " in " pearl
Star " is most strong before coming off, but milter now is overdone, it is most important that what when
The milter of time has meets the rapid thick seminal fluid of milky for scattering of water, and does not hand over clear, it is impossible to
All check at any time, grasp is incorrect to directly affect fertility rate and hatchability；3rd, dig ovum and check that each tail is female
Fish will dig ovum, not only time-consuming but also hinder fish, and technology is difficult to grasp；4th, B ultrasonic discriminating not only takes, no
It is that professional or the people without abundant practical operation experience possibly cannot judge its accuracy.Cause
This can find one kind and not hinder fish, do not take, and the method that general fishing ground staff is easily mastered is accurate
Really judge parent population maturity, reach optimal spawning effect, so as to reduce the death rate and the fish of postpartum parent population
Seedling abnormal rate, improve fertility rate and hatchability, in terms of China's fishery breeding have positive effect and
Profound significance.Author research schizothoracin artificial propagation during, in the past few years by analysis, instead
Multiple practice, has summed up a kind of new method for differentiating schizothoracin parent population maturity.Sentence with the method
The maturity of disconnected Schizothorax grahami parent population, spawning rate reaches more than 90%, as shown in table 1.
- 2014 years 1 2008 years schizothoracins of table are hastened parturition situation
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided one kind differentiate schizothoracin parent population property into
The method of ripe degree.
Technical scheme is as follows：The present invention provides a kind of discriminating schizothoracin parent population maturity
Method, in the mating period of the schizothoracin, health reaches sexually matured being caught from parent fish rearing pond
Male and female parent population, fish scoop in preprepared container or fish folder in, visually see fish head kiss end,
Have " star-pursuing " is milter, and without " star-pursuing " is raun.
Currently preferred, the magnifying glass checks male and female parent population caudal peduncle, and caudal peduncle both sides lateral line scales are attached
It is poor without raised short grained parent population maturity on nearly scale, it is impossible to as use of hastening parturition；Caudal peduncle both sides side line
There is raised little particle near squama on scale, parent population maturity is optimal when proportion is caudal peduncle 1/4-3/4,
Spawning effect is best；There is raised little particle near the lateral line scales of caudal peduncle both sides on scale, proportion is not enough
Parent population maturity is general during caudal peduncle 1/4, can directly be hastened parturition, it is also possible to cultivate 5-10 days it is laggard
Row is hastened parturition；Raised little particle near the lateral line scales of caudal peduncle both sides on scale extends to whole caudal peduncle, parent population
It is overdone, it is impossible to be used as breeding then.
Currently preferred, the magnifying glass checks male and female parent population caudal peduncle, and caudal peduncle both sides lateral line scales are attached
It is poor without raised short grained parent population maturity on nearly scale；Have convex on scale near the lateral line scales of caudal peduncle both sides
Little particle is played, parent population maturity is optimal when proportion is caudal peduncle 1/4-3/4；Caudal peduncle both sides lateral line scales
There is raised little particle on neighbouring scale, parent population maturity is general during proportion deficiency caudal peduncle 1/4；Caudal peduncle
Raised little particle near the lateral line scales of both sides on scale extends to whole caudal peduncle, and parent population is overdone.
Beneficial effects of the present invention are as follows：
Using such scheme, the present invention checks the head of fish by adopting naked eyes, male and female is checked with magnifying glass
The method of parent population caudal peduncle so that differentiate that piscinity is ripe accurate, quick, fish is not hindered, easy to operate and easy
The advantage of grasp.
Specific embodiment
It is below specific embodiment, the present invention is described in detail.
The present invention provides a kind of method for differentiating schizothoracin parent population maturity, in the numerous of the schizothoracin
