연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

The black seabream Acanthopagrus schlegelii is an important species for aquaculture in Korea. There are, however, no reports on the physiological responses to hypoxia in this species. The objective of this study was to evaluate the effects of acute hypoxia on the physiological stress responses (plas...

질의응답

핵심어 질문 논문에서 추출한 답변
스트레스란? 스트레스는 생물체의 항상성이 내인성 또는 외인성 자극에 의해 위협받는 상태이며, 스트레스 반응이란 개체가 이러한 자극을 극복하는 전략으로 알려져 있다(Chrousos and Gold, 1992). 양식 행위에서 스트레스 반응을 유발하는 요인으로는 수질악화 (저산소 등), 핸들링, 수송, 감금, 선별, 화학약품 등이 있다(Barton and Iwama, 1991; Davis, 2006).
경골어류에서 코티졸이 스트레스 지표로 이용되는 이유는? 경골어류에서 코티졸은 주요 corticosteriod로 스트레스를 받는 동안 혈장의 코티졸 농도가 뚜렷하게 상승하므로, 코티졸은 주로 스트레스 지표로 이용된다(Mommsen et al., 1999).
양식 행위에서 스트레스 유발요인은 무엇인가? 스트레스는 생물체의 항상성이 내인성 또는 외인성 자극에 의해 위협받는 상태이며, 스트레스 반응이란 개체가 이러한 자극을 극복하는 전략으로 알려져 있다(Chrousos and Gold, 1992). 양식 행위에서 스트레스 반응을 유발하는 요인으로는 수질악화 (저산소 등), 핸들링, 수송, 감금, 선별, 화학약품 등이 있다(Barton and Iwama, 1991; Davis, 2006). 어류가 스트레스 유발요인에 노출되는 동안 3차의 반응으로 분류되는 생화학적 및 생리학적 변화를 연속적으로 겪게 된다(Wendelaar Bonga, 1997).
