“…Due to characteristic differences between male and female fish, the mono-sex population is beneficial for commercial aspects in various species. For example, the female seedlings of Atlantic salmon [ 164 ], olive flounder [ 165 ], and rainbow trout [ 166 ] are preferred in aquaculture as they either grow faster than males, or males generally reach sexual maturity earlier than females, resulting in the loss of growth potential and flesh quality [ 167 ]. In sturgeons, females are more valuable owing to caviar in their gonads.…”

Germ cell transplantation technology enables surrogate offspring production in fish. This technology has been expected to mitigate reproductive barriers, such as long generation time, limited fecundity, and complex broodstock management, enhancing seed production and productivity in aquaculture. Many studies of germ cell transplantation in various fish species have been reported over a few decades. So far, surrogate offspring production has been achieved in many commercial species. In addition, the knowledge of fish germ cell biology and the related technologies that can enhance transplantation efficiency and productivity has been developed. Nevertheless, the commercial application of this technology still seems to lag behind, indicating that the established models are neither beneficial nor cost-effective enough to attract potential commercial users of this technology. Furthermore, there are existing bottlenecks in practical aspects such as impractical shortening of generation time, shortage of donor cells with limited resources, low efficiency, and unsuccessful surrogate offspring production in some fish species. These obstacles need to be overcome through further technology developments. Thus, we thoroughly reviewed the studies on fish germ cell transplantation reported to date, focusing on the practicality, and proposed potential solutions and future perspectives.

“…However the commercial use of genetically modified fish in aquaculture is still up for discussion, since the first commercialization of genetically modified fish, GloFish, was in 2003 (Gong et al, 2003), and further, the United States and Canada allowed the commercial processing and selling of the AquAdvantage ® Salmon (Ledford, 2015). To prevent potential adverse impact on the environment, biological and environmental containments should be applied in the production of TG betta, for example using the closed containment aquaculture system (Crouse et al, 2021). Furthermore, the transgenic betta should be bred as sterile-triploid fish to avoid reproduction.…”

Highlight ResearchThe F2 of GH-transgenic B. imbellis was successfully producedThe transgene inheritance by the F2 fish was more than 90%The growth and body size of transgenic fish was significantly higher than controlF2 fish reached a larger body size in a shorter period compared to the F1 AbstractIn our previous research, we had successfully produced G0 and G1 Pangasianodon hypophthalmus growth hormone (PhGH) transgenic B. imbellis, native ornamental betta from Indonesia, which its giant-sized variant has valuable price for the breeders. The G0 and G1 transgenic (TG) fish showed higher growth rate and body size compared to the non-transgenic (NT) fish. The study was aimed to produce and evaluate the consistencies of transgene transmission and expression in G2 generation. The growth rate and body size between TG and NT fish was also compared. The G2 generation was produced using crosses between TG and NT G1 fish: ♂TG × ♀TG, ♂TG × ♀NT, ♂NT × ♀TG, and ♂NT ×♀ NT. Fish were reared for 12 weeks, and transgene detection was performed using the polymerase chain reaction method (PCR) on isolated DNA from the caudal fin clips. The endogenous and exogenous GH expression analysis was conducted using the quantitative real-time PCR (qPCR) method. The results showed that the inheritance of the GH transgene by the G2 fish was more than 90% in all transgenic crosses. Endogenous GH was expressed at the same levels in the brain of TG and NT fish, but the exogenous GH expression was highly detected only in the TG fish. The G2 transgenic fish had a higher specific growth rate, up to 31%, compared to the control. The body length of TG crosses were 23−35% higher and had 111−135% higher body weight compared to NT fish. These results showed a promising approached in mass-producing stable lines of giant-sized betta using the GH-transgenic technology.

“…Alternatively, there has been increasing interest in developing closedcontainment recirculating aquaculture systems (RAS), which can be ascribed in part to their higher bio-security, better control of rearing conditions and ability to dispose of waste properly, for instance, for coho salmon. 37,42 However, the high levels of precocious maturation experienced in RAS for some salmonids (e.g., up to 80% of males 43 and in a rare case, 67% of females 44 by harvest time for Atlantic salmon) can severely compromise their economic profitability. Farming sterile fish would eliminate the possibility of sexual maturation prior to harvest and allow the fish to reach a larger size by extending the potential rearing period.…”
