This paper reviews some Thai research papers for referable benefit of international countries. The relationships of fecundity with body length and weight of wild population are related （F = 0.54L3339, F = 435.41W^S399）. Length-weight relationships of both sexes are W = 0.0059L3044s. Sex ratio is 1：1 and spawning season starts during March to June, the egg is adhesive demersal. Average mature size of both sexes are from 40-60 cm TL and 1,100-2,900 g. Effect of 3 types of hormone on induced ovulation, including HCG, pituitary gland, and buserelin in combination with domperidone are not signiticantly different （P 〉 0.05）. Hatching occurs in 24-25 hours after fertilization. The hatching percentage is 80%. Nursing and feeding strategies are also reviewed in this paper.展开更多
