摘要	This study provides a novel record of the reproductive behaviour of the Kong skate (Okamejei kenojei) in captivity. These skates were found to mate and deposit eggs at a temperature of 16.5 +/- 0.5 degrees C. The results showed that 76.13% of the eggs possessed one yolk, 0.77% of the eggs possessed two yolks and 23.11% of the eggs had no yolk (N = 1043). The deposition of non-yolk and double-yolk eggs was random. A total of 100 eggs were collected. After nearly 92 +/- 5 days of incubation, 28 eggs failed to hatch, and 72 skates were successfully hatched with a female-to-male ratio of 1:1 (P > 0.05). The results enrich our knowledge of the reproduction in cartilaginous fishes and can inform management and conservation strategies for this species.
