主 题:tilapia-derived strain genetically improved
摘 要:DEAR EDITOR, Genetically improved farmed tilapia (GIFT)and GIFT-derived strains account for the majority of farmed tilapia *** male tilapias grow much faster than females,they are often considered more desirable in the aquacultural *** reversal of females to males using the male sex hormone 17-α-methyltestosterone (MT)is generally used to induce phenotypic males during large-scale production of all male ***,the widespread use of large quantities of sex reversal hormone in hatcheries may pose a health risk to workers and ecological threats to surrounding environments. Breeding procedures to produce genetically all-male tilapia with limited or no use of sex hormones are therefore urgently needed.
