The invention relates to the technical field of fry breeding of the cross-banded sea bream, and discloses a method for reducing the deformity rate of the fry of the cross-banded sea bream. Feed the rotifers fortification; from the 9th to the 12th day of feeding the rotifers, feed the nutritious Artemia nauplii, and gradually reduce the feeding of the rotifers; the rotifer nutrition enhancement method is as follows: Disperse into the aqueous solution of biological bait I for nutritional enhancement, and biological bait I includes Schizochytrium powder, astaxanthin powder, vitamin A and vitamin D; the nutritional enhancement method of Artemia nauplii is as follows: Disperse rotifers into biological bait II Nutritional enhancement in the aqueous solution of the bio-bait II includes Schizochytrium powder and astaxanthin powder. The method of the invention can reduce the deformity rate of the fry from the source, and the deformity rate is reduced to less than 10%, which is helpful for the popularization of large-scale artificial breeding of the sea bream. |
