“…If we can get the PGCs from the offspring of the survivor, in which genes for disease resistance are expected, after mass mortality, we could easily increase the number of fish-seed with disease tolerance. Transgenic techniques were developed to enhance growth in several fish species (Devlin et al, 1994;Nam et al, 2001Nam et al, , 2002. If the generation time is shortened, these transgenic lines are useful candidates for surrogate parents for rapid propagation and breeding of fish-seed.…”

“…Chromosome set manipulation techniques make it possible to realize sex-manipulation, sterilization and establishment of inbred stains by cloning (Arai, 1997). Transgenic techniques were also developed to enhance growth (Devlin et al, 1994;Nam et al, 2001Nam et al, , 2002. Genetic infrastructures, such as whole genome sequencing, linkage mapping and EST, are required for further improvement by maker-assisted selection, but at present only exist for a limited number of aquaculture species (Taniguchi, 2000;Coimbra et al, 2003;Ohara et al, 2005).…”

The purpose of this review is to introduce surrogate production as a new technique for fish-seed production in aquaculture. Surrogate production in fish is a technique used to obtain the gametes of a certain genotype through the gonad of another genotype. It is achieved by inducing germ-line chimerism between different species during early development. Primordial germ cells (PGCs) are a key material of this technique to induce germ-line chimera. In several species, it has been reported that PGCs differentiated from the blastomeres inherited some maternally supplied mRNA located at the terminal regions of the early cleavage furrows. PGCs from donor species (or strains) are isolated and transplanted into host species to induce the germ-line chimera.Four methods for inducing germ-line chimera, namely, blastomere transplantation, blastoderm-graft transplantation, transplantation of PGC from the genital ridge and transplantation visualized PGC with GFP fluorescence, are described. Several problems preventing the successful induction of germ-line chimera in various fish species are mentioned. Surrogate production, however, has the possibility to allow efficient fish-seed production and effective breeding and transfer of biodiversity to an aquaculture strain.Conservation and efficient utilization of genetic resources will be achieved through surrogate production combined with the cryopreservation of PGCs.

“…The gene transfer technique is an attractive approach for genetic improvement of aquaculture stocks (Hackett and Alvarez, 2000;Devlin et al, 1994). However, until now, transgenic fish have been produced by direct introduction of foreign genes into oocytes or early embryos.…”

“…Email: z.zhu@lily.whihb.ac.cn GH-transgenic fish exhibited higher growth rates than the controls (Zhu et al, 1986(Zhu et al, , 1989Chourrout et al, 1986;Dunhan et al, 1987;Rokkones et al, 1989;Zhang et al, 1990;Du et al, 1992). The most dramatic superfish was produced by Devlin et al (1994) who inserted an all-salmon gene construct (pOnMTGH1) into coho salmon Oncorhynchus kisutch (Walbaum). On average, the transgenic salmon were more than 11-fold heavier than non-transgenic controls, with a range from no growth stimulation to one individual 37 times larger than controls.…”

“…In the present study, on average, the F 4 hGH-transgenic red carp showed specific growth rate of wet weight values 19-25% higher than those of the controls. Growth-promoting effects of exogenous growth hormone gene have been observed in a number of GH-transgenic fishes, including hGH-transgenic loach Misgurnus anguillicaudatus (Cantor) and goldfish (Zhu et al, 1986(Zhu et al, , 1989, GH-transgenic rainbow trout Oncorhynchus mykiss (Walbaum) (Chourrout et al, 1986), hGH-transgenic channel catfish Ictalurus punctatus (Rafinesque) (Dunham et al, 1987), rGH-transgenic common carp (Zhang et al, 1990), GH-transgenic coho salmon (Devlin et al, 1994), and F 1 and F 2 hGH-transgenic red carp (Wei et al, 1992;Cui et al, 1996b). The present study is probably the first report that the growth promoting effect of foreign GH-gene could persist in the F 4 generation.…”

The F 4 generation of human growth hormone (hGH) transgenic red common carp Cyprinus carpio had significantly higher growth rates than the non-transgenic controls. Protein and energy intakes were significantly higher in the transgenic carp than in the controls fed the 20% protein diet, but were not different between the two strains fed diets with 30 and 40% protein.Faecal protein loss, as a proportion of protein intake, was significantly lower in the transgenics than in the controls fed diets with 20 and 30% protein, but was not different between the two strains fed diet with 40% protein. Faecal energy loss, as a proportion of energy intake, was significantly lower in the transgenics than in the controls fed diet with 20% protein, but was not different between the two strains fed diets with 30 and 40% protein. Recovered protein, as a proportion of protein intake, was significantly higher in the transgenics than in the controls fed all diets, whereas recovered energy was significantly higher in the transgenic fish fed the 40% protein diet. For fish fed each diet, the transgenics had significantly higher body contents of dry matter and protein, but lower contents of lipid than the controls. It was concluded that transgenics were more efficient in utilizing dietary protein than the controls. At a lower dietary protein level, transgenics achieved higher growth rates mainly by increasing feed intake; at higher levels of dietary protein, transgenics achieved higher growth rates mainly through a higher energy conversion efficiency. 1998 The Fisheries Society of the British Isles
