We investigated the infection of nervous necrosis virus (NNV) in seven band grouper Hyporthodus septemfasciatus broodstocks, which have been reared in aquaculture farms in South Korea during 2012-2014. To investigate the prevalence of NNV within the broodstock, egg, sperm, and blood were sampled in ...

능성어란 무엇인가? | 능성어(Hyporthodus septemfasciatus)는 분류학적으로 농어목 바리과에 속하는 열대어종 해산어로, 국내에는 남해안 및 제주도 연안에서 서식한다. 능성어는 저지방, 고단백으로 맛이 좋아 횟감 등의 식용으로 인기가 높으며, 단가가 비싸 고급양식 품종으로 주목 받고 있다. | |
능성어 양식이 활성화 되지 못한 이유는 무엇인가? | 우리나라는 2003년에 능성어 인공 종묘생산이 성공했지만 그 이후 산업화는 미흡한 실정이었으며, 국내 능성어 양식은 90년대 후반부터 실시되어 2010년 양식어장 15 개소에서 총 269톤을 생산하였으며, 2011년 150톤, 2013년 56톤을 생산하여 줄어느는 양상을 보이고 있다(statistics Korea, 2017). 능성어 양식이 활성화 되지 못한 이유는 체계적인 친어 관리 매뉴얼이 확립되어 있지 않은 관계로 안정적인 종묘생산이 어려웠고, 아열대성 어종인 능성어를 양식하기에 적합한 지역이 확인되지 못하였던 점, 낮은 종묘생산 효율 그리고 질병에 의한 폐사 등 이 원인으로 작용하였다(Hong et al., 2015;Kim and Kim, 2015). | |
바이러스성신경괴사증이 발생하는 어종은 무엇이 있는가? | , 2002). VNN은 일본, 대만, 노르웨이, 프랑스, 인도네시아 등 전 세계적으로 광범위한 지역에서 발병하며 능성어, 흑점줄전갱이(Pseudocaranx dentex), 넙치(Paralichthys olivaceus), 유럽농어(Dicentrarchus labrax), 홍민어(Sciaenops ocellatus), 황점볼락(Sebastes oblongus) 등 5목 11과에 걸쳐 25종의 어종에서 발병한다(Munday et al., 2002). |
