Consideration of Blood Serum Biochemical Parameters of Yellow Fin Sea Bream (Acantopagrus latus Houttuyn, 1782) and Orange-Spotted Grouper (Epinephelus coioides Hamilton, 1822)

Serum biochemical parameters are important aspects in the management of endangered species. The values of these parameters can be used for confirming the maturity and for monitoring any changes in the quality of waters and related soils. The aim of this research was to determine the reference values of biochemical factors in Acantopagrus latus and Epinephelus coioides. Blood samples were collected from captured fish from coastal waters of Chabahar (Ramin waterfront). Serum levels of glucose, Blood Urea Nitrogen (BUN), cholesterol (CHO), triglyceride, total protein, albumin, calcium (Ca2+), phosphorus (P), sodium (Na+), bilirubin and potassium (K+) were measured. The results showed that the levels of albumin and bilirubin in E. coioides were significantly higher than A. latus and there were significant differences in all of the serum values (except P and glucose) between A. latus and E. coioides (P < 0.05). It can be concluded that the values of blood biochemical parameters may be affected by physiological factors such as the species of fish.
