dc.description.abstract The hatchability of the artificially induced hybrid between two groupers (family Serranidae), red spotted grouper (Epinephelus akaara) and brown-marbled grouper (E. fuscoguttatus) that lives in different habit environment was investigated. There was no difference in the required time of each developmental stages after fertilization between hybrid (red spotted grouper ♀ × brown-marbled grouper ♂) and purebred (red spotted grouper ♀ × ♂) and required 25.6 hours to hatch at incubated in 25∘C , but a noticeable unequal cleavage in cell size was observed in hybrid eggs unlikely to purebred. The hatching rate of fertilized eggs of hybrid was generally low across the four incubate temperatures (22, 25, 28, 31∘C ) with highest 9.8% in 25∘C . This study demonstrated the possibility of artificial hybridization between two groupers, red spotted grouper and brown-marbled grouper, thus preparing the groundwork on developmental characteristics, deformities of hatched larvae and early survival ability for further studies on aquaculture. 서식 환경이 다른 바리과(family Serranidae) 어류 두 종, 붉바리 (Epinephelus akaara)와 brown-marbled grouper (E. fuscoguttatus)의 종간 잡종 수정란의 부화율을 조사하였다. 잡종(붉바리 ♀ × brown marbled grouper ♂)의 수정 후 각 발생단계까지 소요시간은 붉바리 순종과 차이가 없었으며, 부화 소요시간은 25∘C 에서 25.6시간이었다. 잡종은 붉바리 순종과는 달리 비균등 난할이 분명하게 관찰되었다. 잡종의 부화율은 네 수온(22, 25, 28, 31∘C )에서 대체적으로 낮았으며, 25∘C 에서 9.8%로 가장 높았다. 이상의 연구에서 서식환경이 서로 다른 바리과 두 종간 잡종이 생산 가능한 것으로 조사되었으며, 향후 산업적 활용성을 검증하기 위하여 발생 양상, 기형률 및 초기 생존율 등에 관한 면밀한 연구가 필요할 것으로 판단된다. -
