To examine the effects of insulin-like growth factor (IGF)-I on the growth performance of fish, juvenile red snapper Lutjanus erythropterus with an initial body weight of approximately 12 g were fed diets containing different amounts of IGF-I containing Escherichia coli BL21 powder (BL21-tlGF-I). The growth of fish was enhanced by lower doses (0.25, 0.5 and 1%), but deteriorated at higher amounts...

A transgene construct carrying rainbow trout growth hormone (rtGH) complementary DNA driven by a common carp b-actin promoter was introduced into silver sea bream by electroporating the sperm with the rtGH transgene and using...
