초록
양식현장에서 선별작업시 처리되는 사육수조의 수심감소와 어류이송에 따른 넙치 (대, 소)와 큰민어의 스트레스 반응을 알아보기 위하여 스트레스 지표로 알려져 있는 혈액학적 요인, 코티졸, 글루코스, 젖산 및 삼투질 농도를 조사하였다. 수심감소에서 넙치대의 Ht는 실험전
The effects of water level reduction in rearing tank and fish transference during fish selection process on the stress response (hematological factors, cortisol, glucose, lactic acid and osmolality) of tank-reared olive flounder Paralichthys olivaceus of large (FL), small (FS) and Japanese croaker, Nibea japonica (JC) were examined in running seawater culture system. The water level of rearing unit was lowered from 33 cm to 8 cm in the course of 2 minutes in the water level reduction experiment. The fish were removed from rearing tank (12 ton) to 450 L tank in 30 seconds after capture in the fish transference experiment, In water level reduction, the hematocrit of FL was significantly increased from
