The study was designed to know the characteristics of reproductive biology and embryonic development regularity of Sebastes hubbsi, to accumulate basic data for further study on protection and sustainable utilization of this fish resources. The reproductive biology and embryonic development of S. hubbsi were studied based on 283 samples of breeding stocks caught in spring in Jiaozhou Bay, Qingdao, from April to May 2015. After obtaining fertilized eggs from female fish, we observed the embryonic development using the microscope and examined the morphological characteristics of each development stage. The collected samples had a body length ranging from 62 to 137 mm, a body weight ranging from 9.4 to 126.8 g, and an age range of 2 to 4 years. The female-male sex ratio was 1.85:1 and the first sexual maturity age was 2 years. The body length of the species at the first sexual maturity age was 70.6 mm. The individual absolute fecundity F ranged from 656 to 9235 (mean 3176) eggs. The individual length-specific fecundity to body length F_L ranged from 12 to 67 (mean 29) eggs per mm and the individual weight-specific fecundity F_W ranged from 72 to 140 (mean 108) eggs per gram. The egg of S. hubbsi was globular with a light yellow color and had multiple oil globules of varied size. The sterilized eggs would sink in the water with an average diameter of (1.50±0.03) mm. With the embryonic development, all oil globules of the egg gradually merged into a single one until at about the late gastrula stage, and the eggs gradually changed to pear-shaped from the heart beat stage. The newly hatched larvae were still in the ovarian cavity and had a total length of (5.57±0.06) mm. The embryonic development of ovoviviparous teleost Sebastes hubbsi seems to be similar to most of the marine teleost fishes, but there were still some characteristics different from others such as in pigmentation, oil globule variation, morphological change of eggs, etc.
