Description
Technical field
The method that male yellow cartfish breeding population is set up in supermale fish and the mating of physiology raun belongs to the method that a kind of fish physiological inheritting is bred, and is with technology such as artificial sex reversal, screening, test cross and expansion group control fish sex technical field.
Background technology
Production unisexuality hero has several method, and available (Aquaculture2001 is 197:283-301) as hand picking, the direct inductivity reverse of androgenic hormone, androgenesis, interspecific cross, artificial induction triploid and genetic method etc.But, and can not accurately distinguish female milter because of the labour intensity of hand picking is big.Reverse with the direct inductivity of sex hormone, the danger of sexual hormone residues, many countries forbid already.Serious technology barrier such as then there is inductivity in androgenesis, survival rate is low and YY ♀ physiology raun fertility is extremely low only rests on the experimental stage, does not still have successful example.And three times of artificial inductions not can not accomplish 100% unisexuality, have only Tilapia mossambica interspecific cross and genetic method to achieve success, and apply on producing.But interspecific cross is only limited to several hybrid combinations that Tilapia mossambica belongs to, and spawning rate is lower.The genetics technology that only is called GMT is applicable to the fish of male gamete abnormal shape, and method is reliable, stable, and environmentally friendly, without any adverse effects, can produce full milter in a large number.As far back as last century five, the sixties, Japan Yamamoto (Genetics40:406-419, Exp.Zool.137:227-262, Genetics55:329-336) when blue or green Medaka Sex determination of research and sex-linked inheritance, utilize female sex hormone that XY ♂ milter is reversed into XY ♀ physiology raun, and with the mating of XY ♂ milter, obtain YY ♂ supermale fish first, proof YY ♂ supermale fish can survive, and can feminize, become YY ♂ physiology superfemale fish, YY ♀ physiology superfemale fish and the mating of YY ♂ supermale fish just can produce YY ♂ supermale raun in a large number.1980, China Yang Yong select (Acta Genetica Sinica, 1980,7 (3): 241-246) wait application three series mating approach to produce hereditary complete male Mozambique Tilapia mossambica and succeed, basically be exactly the method for the reverse of usability hormonal and offspring's test cross, obtain YY ♂ supermale fish; 1989, Varadaraj etc. also proposed similar method and obtain YY ♂ supermale Mozambique Tilapia mossambica.After this, Mair etc. 1988, Baroillerant Jalabit 1989, Scoff etc. also delivered relevant research paper in 1989 in succession and propose identical method, obtain YY ♂ supermale bolti (Ph.D.thesis.University of maies.Swansea, Aquat.Living Resour.2:105-116, Aquaculture, 78:235-257) on the basis of these work, the breeding plan that Mair (Aquat.Sci.54:396-404) etc. reported the complete male bolti of large-scale production in 1997, their result of study, just so-called full milter Genetic Manipulative Technology (
).This technology is to obtain YY ♂ supermale fish and YY ♀ physiology superfemale fish at last by the hormonal reverse of five generations half and offspring's test cross, and produces the full milter of XY ♂ by YY ♂ supermale fish and the common raun of XX ♀.Adopt the breeding cycle of this technology longer, and, prevent to mix, could achieve success at last by for the necessary strict control of the test fish of test cross.As seen, for generation cycle long fish, just may not be first-selected method, must employing other effective technical means comparatively.1989, Varadaraj.K. (Current ScienceVol.58, NO, 8:434-441) grade has reported that hormonal reverses the Tilapia mossambica in conjunction with gynogenesis technology generation supermale Mozambique, this technology it is said and the output of YY ♂ supermale fish can be brought up to 50% from 25%, and can shorten 22~8 months breeding time, and the scheme of the full milter of commercial large-scale production is proposed.But do not see the report of on producing, applying.There is no report as for the sex reversal of yellow cartfish and gynogenesis and YY ♂ supermale fish, full milter.Aquatic institute of the Chinese Academy of Sciences had once applied for patent (application number 200610166518.8, publication number: CN1994027A) in 2006.12.28 with regard to " sex reversal and gynogenesis continue to produce complete male yellow cartfish method ".Liu Hanqin etc. mention the integrated technology that adopts sex reversal to combine with gynogenesis first, set up the breeding of method (aquatile journal, 2007,31 (5): 98-101) that continue to produce supermale yellow cartfish YY ♂ and complete male yellow cartfish XY ♂.It is compared with external GMT genetics technology, can shorten two generations of breeding cycle, improves about 1 times of supermale fish output capacity.
From the above file of quoting as can be known: some kinds of methods having reported production unisexuality milter; Utilize female sex hormone that milter is reversed into the physiology raun, can obtain the supermale fish through mating, test cross; Utilize full milter Genetic Manipulative Technology (GMT), reverse and offspring's test cross obtains YY ♂ supermale fish and YY ♀ physiology superfemale fish at last, and can produce the full milter of XY ♂ through the hormonal in some generations; The method that utilization sex reversal and gynogenesis continue to produce complete male yellow cartfish is disclosed.These innovation and creation have promoted the development of breeding of fish cell engineering and artificial sex controlling technology.But also have following problem simultaneously: the gynogenesis cold shock is handled has damage to genetic material; The survival rate of two letter body gynogenesis fishes is undesirable; Large-scale production waits to improve; Breeding cycle has to be shortened.
