Abstract
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.
