Abstract

The aim of this study was to compare serum total cholesterol and cholesterol types of cultured rainbow trout (CRT) (Oncorhynchus mykiss) and cultured brook trout (CBT) (Salvelinus fontinalis) cultivated under the same water conditions. Fishes used in the research were randomly captured from pools and five pieces (five replication) were used for each group. The average weight of fish is 80 g for CRT and is 120 g for CBT. CRT and CBT have been fed with feed with 45 to 50% crude protein twice a day. The levels of serum samples excluding high density lipoproteins (HDL) obtained from the CBT were found to be higher (p<0.05) than that of CRT. Finally, higher serum samples in CBT could have resulted from difference of growth and size, species, age, the cycle of sexual maturity of fish.

Key words: Rainbow trout, brook trout, total cholesterol, high density lipoproteins (HDL), low-density lipoproteins (LDL), very-low-density lipoprotein (VLDL).
