発明の名称 (英語) TRANSPLANT FISH PRODUCTION METHOD, TRANSPLANT FISH, HYBRID FISH SPECIES PRODUCTION METHOD, AND HYBRID FISH SPECIES UPDATE
発明の概要(英語) This transplant fish production method includes selecting a donor fish species, selecting first and second fish species which are a combination that could be sterile, producing a hybrid fish species of the selected first fish species and second fish species, and transplanting reproductive cells of the donor fish species into the produced hybrid fish species.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, natural resources continues to gradually decreasing trend of the amount of fishing is a fishing, saltwater fishing is the total volume ratio in accordance with this increase in the percentage of the amount of production has been increased. On the other hand, in the culture of marine fish, natural product to a size of the still often the case that the developing seedling. For this reason, together with increase of the importance of resource management, fish farming completely introduced more strongly demanded.
Aquaculture is complete, a target fish from fertilized eggs of the seedling produced artificially, the obtained artificial seedling, distributed as a product, further in addition to this, the resulting artificial seedling and some individuals of the parent to fish cultivation, producing gametes, gametes obtained that it is utilized for culturing the, natural resources are completed without depending on the style refers to aquaculture. In order to realize the aquaculture completely first, for the purpose of the parent fish from the fish, both the quality and quantity to obtain the sufficient seedling must be gametes. Seedling to obtain the sufficient gametes, the maintenance of the parent fish of sufficient size and housing facility, suitable according to the present and growing is indispensable and the induction of egg laying, a lot of space and effort. For this reason, many farmer can easily be implemented to the extent that the use of seedling production to establish said fish species is small.
As a technique which can solve this problem, the surrogate host fish technique has been attracting attention as (surrogate broodstock technology). The present technique, so as to obtain the gametes of the donor and target fish species, for the production of gametes is attempted and the recipient fish species, undifferentiated germ cells of the donor and recipient, the recipient fish method is used as a surrogate host. Undifferentiated germ cells as donors, primordial germ cells, spermatogonia or oogonia illustrated in cells. The present technique, in other words, the gonads of recipient donor germ cells in the differentiation or proliferation by, to produce gametes of the donor, then, the next generation of donor to produce a population of individuals technique. In the case of fish, and male gametes is motility, sperm termed, female gametes is no motility, referred to as egg. Surrogate host fish in that technique, in the case of obtaining the sperm, the male recipient transplanted donor germ cells, on the other hand, in the case of obtaining the egg is, female germ cell into a recipient of the donor.
Surrogate host fish techniques include, for example, the 2003-235558 and the publication JP Fisheries for Global Welfare and Environment, 5th World Fisheries Congress 2008 (2008) p209-219, landlocked (masu salmon, Oncorhynchus masaou) spermatogonia of the donor, recipient of the same family of the same group as the male and female fin-implanted egg of the landlocked (rainbow trout, Oncorhynchus mykiss) by obtaining sperm, and the next generation of surrogate host of fin-fish or landlocked a method for the production of the individual is.
Science Vol.317 (2007) p1517 is, 3 times to produce a rainbow trout and rainbow trout of sperm and egg derived from acid to produce fish of the surrogate host may be sterile, the sterility of the germ cells of the surrogate host or landlocked fish in an efficient manner by implanting a sperm and the egg to obtain the landlocked, a method for the production of the next generation individual landlocked described. In addition, JP Patent Application 2006-101845, 3 to produce a haploid or landlocked and, to this, a method of transferring primordial germ cells derived from a fin is disclosed. According to these methods, and/or sperm derived from the recipient egg is hardly formed as it is not, a number of recipients of gametes of the donor gametes from the pick up a complexity that can be reduced, the gametes of the donor efficiently can be obtained and described.
Is Fisheries Science Vol.77 (2011) p69-77, spermatogonia of the debris when implanted in a drumfish (nive broaker, Nibea mitsujurrii), drumfish be captured of the gonads, did not result in the production of gametes is described. Biology of Reproduction Vol.82 (2010) p896-904 is, spermatogonia of a drumfish when transplanted into a chub mackerel, drumfish is taken into the germ cells to the gonad chub mackerel, proliferating is also confirmed, and it was not for the production of gametes is described.
