Autotransgenic and allotransgenic manipulation of growth traits in fish for aquaculture: a review

摘要: It is noteworthy that the use of transgene elements homologous to both structural gene and promoter region sequences are more effective than heterologous ones for growth hormone (GH) transgenesis in farmed fish species. The generation autotransgenic carrying GH-transgene construct (of which originate from same species only) has been given considerable attention as a potential means produce desirable strain acquiring significantly improved phenotype. Currently, several growth-enhanced lines including mud loach, carp tilapia, have developed or ongoing aquacultural purpose. This review considers generation, development prospects manipulation growth, comparing performance currently available strains with those relevant fast-growing allotransgenic fishes.
