【Abstract】 Devil Stinger ( Inimicus japonicus ) is one of the notable species of marine edible fishes suitable for shallow sea farming. Parents fishes of Devil stinger were caught from the coastal area of Beibu Gulf in 1998～1999. After temporarily rearing, the mature parents fishes were induced spawning. The hormons and dosages adopted for injection were: LRH A 3 10 μg+DOM 5 mg or HCG 600～800 IU+LRH A 3 30～40 μg per kg of body weight for females and half of the dosages for males. About 1 090 thousand of eggs were collected from the spawning pools. The average rates of fertilization and incubation reached 89 0% and 90 0% respctively in two year productive experiments. A total number of 268 thousands of fries with a body length of 1 8～2 3 cm were produced with a survival rate of 30 7%.更多还原
