Abstract

Of 6,4 Southern catfishes have been induced to ovulation by using different drugs. The serum GTH level increased from 345μg to 6985μg during the ovulation after injection of LHRHA and hCG,but it decreased to 979μg quickly after ovulation.A peak of serum GTH level was also found in the unovulated fish after injection of the same dose of LHRH-A and hCG. However the level increased only 5 times, which was much lower than that of the ovulated fish. And this phenomenon was found after injection of LHRH-A and DOM. The level increased only 6 times.All the results suggested that the GTH was important to induce the final maturation of oocyte and ovulation in the Southern catfish.
