우리나라에서 많이 양식하고 있는 주요 어종의 혈액 성분에 관한 기초 자료를 얻기 위하여, 저수온기(수온 $127^{\circ}C$)에 월동중인 조피볼락(Sebastes schlegeli), 농어 (Lateolarax japonicus), 넙치 (Paralichthys olivaceus), 돌돔(Oplegnathus fasciatus)과 함께 냉수성 어종인 은연어(Oncorhynchus kisutch)를 각 5-6마리씩 마취시키지 않은 상태로 꼬리 동맥에서 채혈하여 혈청 중의 총단백질(TP), 알부민(ALB),중성 지방(TG), 콜레스테롤(CHOL), 포도당(GLC), 리파제(LIPA), 나트륨(Na), 칼륨(K), 염소(Cl), 인(P), 아미노산전이효소(ALT, AST) 등을 혈액분석기로 분석하였다. TP 농도는 2.9-5.1g/dl의 수준이었으며, ALB 농도는 1.2-l.9g/dl의 수준이었다. A/G 비는 은연어가 1.1 정도로 가장 높았고 나머지는 0.5-0.6 정도로 비슷하였다. 지질 성분인 TG와 CHOL 농도도 어종에 따라 달라, 넙치는 TG 농도가 큰 대신에 CHOL 농도가 낮았으며, 농어는 반대로 TG농도가 낮은 대신에 CHOL 농도가 높았다. 두 지질 성분의 합은 넙치가 가장 많아 600mg/dl나 되었고, 농어나 조피볼락(약 400mg/dl), 돌돔이나 은연어(약 300mg/d1)의 순이었다. 혈당(GLC) 농도는 냉수성 어종인 은연어가 넙치에 비해 약 4배 가량 많아 61-76mg/dl이나 되었다. 한편 리파제(LIPA) 활성은 TG 농도와 정반대의 경향을 보여 은연어에서 가장 높았고, 넙치에서는 거의 확인되지 않았다. 무기질 중에서 Na, Cl과 K 농도는 160-204mmo1/l, 137-183mmol/l과 0.5-3.1mmol/l로 유사한 수준이었으나, P농도는 은연어나 조피볼락처럼 비교적 활동성이 강한 어종일수록 많았다. ALT 활성은 넙치가 가장 높았고, AST 활성은 은연어가 높았으며, AST 활성은 모든 어종에서 ALT 활성보다 높았다.

This study was performed to obtain the basic data on the serum components of several marine fish species commonly cultured in Korea. Blood samples taken from five species of fish were analyzed for various components of serum, total protein (TP), albumin (ALB), triglyceride (TG), cholesterol (CHOL), glucose (GLC), sodium (Na). Potassium (K), chloride (Cl), Phosphorus (P), lipase (LIPA), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The fish used were coho salmon(Oncorhynchus kisutch), rock fish (Sebastes schlegeli), sea bass (Lateolabrax japonicus), olive flounder ( Paralichthys olivaceus) and parrot fish (Oplegnathus fasciatuss) reared at the Chungmu Experimental Fish Culture Satation of KORDI. TP concentration of warm-water species (2.9-5.1 g/dl) was higher than that of cold-water species, and ALB concentration was ranged at the level of 1.2-1.9 g/dl. Coho salmon showed the highest ration of A/G(1.1), and the other species were about 0.5-0.6. The concentrations of TG and CHOL, components of lipids, varied with the different species. The concentration of TG was high, but CHOL concentration was low in olive flounder, while the reversed results were shown by sea bass. The sum of these two components was the highest with 600mg/d1 in olive flounder, and about 400mg/d1 for sea bass and rock fish, and 300mg/d1 for parrot lish and coho salmon. Concentration ot GLC in coho salmon and rock fish ranged from 61 to 76mg/d1 which were about lour times higher than that of flounder. The highest lipase activity was observed in coho salmon, while it was nearly nil in flounder. The reversed tendency was found for TG concentration. Mineral concentrations of Na, Cl and K were 160-204 mmol/l, 137-183mmo1/1 and 0.5-3.1 mmol/l, respectively, but no significant difference between the species was observed. However, the concentrations of P were high in relatively active species such as coho salmon and rockfish. AST activity in all species examined was higher than that of ALT with being highest in coho salmon. The highest ALT activity was found in olive flounder.
