The present invention develops a marker of a genetic trait of high growth in Epinephelus fuscoguttatus to thereby provide a method whereby a fish having a genetic trait of high growth can be discriminated without killing any individuals. By using genetic markers developed with regard to Epinephelus bruneus, a genetic map of E. fuscoguttatus was prepared. Cultured E. fuscoguttatus fish were classified into a heavy-weight group and a light-weight group and then subjected to QTL analysis with use of the aforesaid genetic markers.

The object is to provide a method for improving the engraftment ability of transplanted germ cells to the germ gland of a host and thus increasing the transplantation efficiency in transplanting the separated germ cells, in the case of, for example, farm-rising a surrogate parent, i.e., transplanting separated germ cells of a fish to a host fish and inducing the differentiation of the transplanted cells into a germ cell line. As a means for achieving the aforesaid object, disclosed is a method comprising intraperitoneally transplanting separated germ cells into a peri-hatching host fish individual, said separated germ cells being donated by a fish differing in family or species from the host fish, to thereby induce the differentiation of the separated germ cells into a germ cell line, wherein the transplanted host fish individual is raised in a temperature zone, which corresponds to the growth temperature range in the juvenile/fry stage of the fish donating the separated germ cells and in which the host fish can be raised, to thereby improve the engraftment ability of the separated germ cells to the germ gland of the host fish and increase the transplantation efficiency in transplanting the separated germ cells.

For examining whether or not a germ cell derived from a donor fish, which is transplanted into a heterogeneous recipient fish by surrogate fish technique, is grown and matured in a gonad of the recipient fish, it is required to utilize, as an indicator, a trait which is expressed specifically in the germ cell and can be used for distinguishing the recipient fish from the donor fish. Vasa gene, which is a gene specific to a germ cell, is specific to a primordial germ cell and/or a spermatogenous cell/oogonium, and the expression of Vasa gene is not observed in a somatic cell. The sequences of Vasa genes of a tuna, a chub mackerel, a spotted mackerel, an eastern little tuna and a drumfish are determined, and the expression of each of the genes is utilized as a maker for a germ cell. It is possible to detect only a tuna Vasa gene specifically from Vasa gene sequences which are highly conserved in fishes, without the need of sequencing. Therefore, it is possible to identify a tuna-derived germ cell in a gonad of a recipient fish in a simple and reliable manner. Thus, a tuna fish can be grown and bred with good efficiency. By utilizing the above-mentioned knowledge, it becomes possible to detect a germ cell derived from a donor fish from a germ cell derived from a heterogeneous recipient fish with good efficiency even when, besides a tuna fish, a fish belonging to the order Perciformes is used as a donor fish.
