초록

본 연구는 Amphiprion melanopus의 산란 주기 행동 및 산란 후 습성을 조사하고 이를 기반으로 부화장치를 제안하고자 하였다. 연중 수온, 염분 및 광주기가 일정한 인공적인 환경에서 사육된 4쌍의 어미들은 산란주기 및 횟수가 각각 다르게 나타났다. 반면, 수정 후 알 관리는 수컷에 의해서 주로 관리가 되었다. 부화일이 가까워질수록 수컷의 eggfanning 횟수가 증가하였고, 특히, 부화 직전에 더욱 격렬한 행동을 나타냈다. 이러한 정보를 기반으로 에어레이션형, 스프레이형, 회전 수류형 등 3종의 부화장치에 대한 clownfish류 4종의 부화율을 조사한 결과, 회전 수류형 시스템의 부화율이 87.3%로 스프레이형(74.4%)과 에어레이션형(60.5%)보다 높았다. 그리고 회전수류형에서 부화판 개수별(2, 3, 5개)에 따른 부화율은 서로 차이가 없었다. 그러므로 부화자어의 사육 크기를 고려하여 수조 크기를 결정하면 많은 개수의 부화판을 넣어 대량으로 부화시킬 수 있을 것이다.

The marine ornamental industry has become a multi-billion dollar industry these days. As developing, however, this industry has been criticized for the indiscriminate captures and the destruction of the surrounding environment. To circumvent these problems, it is suggested to breed the organisms artificially. While clownfishes Amphiprion sp. and Premnas sp. are the most famous ornamental organisms in the trade, few studies are yet available on the culture and commercial production of these fishes. These studies were performed to investigate the spawning periodicity, behavior and the habits during egg incubation, and to provide the information on the mass hatching system. The spawning periodicity and frequency were different in 4 pairs under the constant condition, temperature, salinity and photoperiod. On the contrary, the male's behaviors for egg incubation are almost same in the all. The egg-fanning activity of the male increased as the developing eggs reaching to the hatching day. Based on the above results, we designed a new artificial hatching system, the rotating type (RT), and compared it with the aeration type (AT) and spray type (ST) that were previously described. RT showed higher hatching rate of 87.3% than AT (74.4%) and ST (60.5%). Also, there were no significant differences in the hatching rate regardless of the number (2, 3, 5) of hatching plates. We suggest RT may accommodate various number of hatching plates and constitute a better hatching system for clownfishes.
