Abstract

This study was conducted to compare the BODY FATTY ACID COMPOSITION of CASPIAN TROUT (Salmo trutta caspius) parrs in different nutritional statuses. 900 CASPIAN TROUT parrs 12.5 (SD±1 g) were kept at various nutritional statuses, i.e. six weeks of full feeding (FFF), three weeks STARVATION and three weeks of REFEEDING (SF), three weeks of feeding and three weeks of STARVATION (FS), two weeks of feeding, two weeks of STARVATION and two weeks of REFEEDING (FSF), two weeks of STARVATION, two weeks of feeding and two weeks of STARVATION (SFS) and six weeks of full STARVATION (SSS). After feeding with various nutritional status, BODY FATTY ACID COMPOSITION was analyzed by GC/FID. Total Monounsaturated Fatty Acids (MUFA) were decreased than control treatment (35.14%) with increase in periods of STARVATION and reached to 32.32% in SSS treatment, while Saturated Fatty Acid (SFA) and Polyunsaturated Fatty Acid (PUFA) were increased from 27.25% and 27.10% in FFF treatment respectively to 32.81% and 31.54% in SSS treatment (P<0.05). Linolenic acid (LNA) content and PUFA C18/C20, 22 index (1.62 and 0.27% in FFF treatment respectively) were decreased with increase in periods of STARVATION and reached to 1.19 and 0.22% in SSS treatment, Icosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) were increased significantly (P<0.05) inversely and reached to 4.55 and 14.12% in in FFF treatment and 6.46 and 15.6% in SSS treatment. In REFEEDING periods, fatty acids have an invert trend and were closed to their levels in control treatment. Therefore, CASPIAN TROUT stores, converts or uses fatty acids selectively in different nutritional statuses to provide its own requirement for energy and essential fatty acids.
