활멸치의 집약적 생산수단에 관한 연구 -II 권현망을 일부 개조한 어구에 의한 어호 및 그 어호물의 축양시험

Study on the Intensive Catching Method of Anchovy for the Live Bait-II Fish catching test by Means of Partially Reconstructed Boat Seine Net and Creel Holding Test of the Catch

재래식 권현망의 천장망을 제거하고 옆판 위 언저리에 뜸을 장치한 어구에 의하여 활멸치의 어획을 시험하고, 동시에 이렇게 어획한 멸치를 버팀대를 써서 축양조를 예인하는 방법으로 축양 시험을 실시한 결과 대략 다음과 같은 결론을 얻었다. 축양개시 15일후의 생잔률은 최고 약 71%여서 다른 어구. 어법에 의한 생잔률 보다는 낮지마는, 권현먕 어구 자체가 한국의 멸치 어업에서는 가장 보편화된 어구이므로, 2차적으로 활멸치를 어획하는데는 충분한 실용성이 있다고 보아진다.

To catch live anchovies which will be used as bait for skipjack fishing, set net, lift net and purse seine net were tried in Korean coastal waters by the authors. Among them the former two methods showed unsuitable to catch in bulk even though the catch showed good survival. The last showed unsuitable result because of the lack of exclusive fishing boat and skilled fishermen. From the viewpoint of practical use, the authors regarded it may be suitable to improve the traditional boat seine net which are used as major fishing gear to catch anchovies in Korea, so far as Korea is concerned. So we tried to catch live anchovies with partially reconstructed boat seine net and to hold the catch in the creel improved by the authors. Even though the result showed less than 70 percent of survival, slightly worse than other fishing methods, the experimented method showed to be practical in catching the live anchovies intensively.
