This study investigated the effects of crude protein levels in diets containing monobasic potassium phosphate (MKP) on water quality and the growth of Japanese eels Anguilla japonica and leafy vegetables in a Hybrid BFT-Aquaponics (HBFT-AP) system. The first experiment (EXP1) was designed to verify ...

국내 서식하는 뱀장어는 어느 종류의 뱀장어 인가? | 국내 서식하는 뱀장어는 극동산 뱀장어(Anguila japonica)로 한국, 일본, 중국 등 동북아시아에서 오래 전부터 양식되어 왔으며, 국내 뱀장어 양식 생산량은 2018년 기준 10,530톤으로 어로 생산량 59톤에 비해 월등히 높은 비중을 차지하고 있다(MOF, 2018). 그러나 양식 종자의 자연 채포 의존에 따른 치어 가격의의 불안정성은 뱀장어 양식 문제의 가장 큰 부분이며, 고밀도 및 빠른 성장을 위한 순환여과시스템(recirculating aquaculture system, RAS) 도입은 기반시설 비용 증가 문제를 발생시킨다. | |
2018년 기준 국내 뱀장어 양식 생산량은 얼마인가? | 국내 서식하는 뱀장어는 극동산 뱀장어(Anguila japonica)로 한국, 일본, 중국 등 동북아시아에서 오래 전부터 양식되어 왔으며, 국내 뱀장어 양식 생산량은 2018년 기준 10,530톤으로 어로 생산량 59톤에 비해 월등히 높은 비중을 차지하고 있다(MOF, 2018). 그러나 양식 종자의 자연 채포 의존에 따른 치어 가격의의 불안정성은 뱀장어 양식 문제의 가장 큰 부분이며, 고밀도 및 빠른 성장을 위한 순환여과시스템(recirculating aquaculture system, RAS) 도입은 기반시설 비용 증가 문제를 발생시킨다. | |
수산양식업에서 발생하는 환경오염을 줄이기 위해서 어떤 방법을 사용하려고 하는가? | 수산양식에서 이를 해결하기 위한 사육수의 재순환 양식방법으로 recirculating aquaculture system (RAS)와 biofloc technology (BFT)가 대표적이나(FAO, 1986; Avnimelech et al., 2015), 국내 순환여과식양식(RAS)은 완전히 물을 재사용하는 것이 아니라 하루에 전체 순환수의 10% 이하가 환수되고 보충되는 것이 일반적이다(Suh et al. |
