متن کاملGrowth Rate, Proximate Composition and Fatty Acid Profile of Juvenile kutum Rutilus frisii kutum Under Light/Dark Cycles
This study investigated the growth rate, proximate composition, and fatty acid profile in juvenile of kutum Rutilus frisii kutum in different dark-light cycles. Fish were stocked randomly in eighteen 2000-L fiberglass tanks and received six photoperiod regimes: natural photoperiod, 24L (light):0D (day), 16L:8D, 12L:12D, 8L:16D and 0L:24D. Application of continuous dark (0L:24D) and an intermedi...
متن کاملEffect of Synthetic Luteinizing Hormone - Releasing Hormone (LHRH-A2) Plus Pimozide and Chlorpromazine on Ovarian Development and Levels of Gonad Steroid Hormones in Female Kutum Rutilus frisii kutum
To assess changes of gonad development and sex steroids hormones of R. frisii kutum, broodfish were captured during spawning season 2010 (March-April) and induced intramuscularly with following hormone treatments: single injections of 1 μg kg b.w. LHRH-A2, combination of LHRH-A2 with two dopamine antagonists as follows: 1 μg kg b.w. LHRH-A2 + 5 mg kg-1 b.w. PIM, 1 μg kg b.w. LHRH-A2 + 2.5 mg kg...
متن کاملChanges of digestive enzymes activity in Caspian Kutum (Rutilus frisii kutum) during larval developmental stages
The ontogenesis and specific activities of pancreatic (trypsin, chymotrypsin, amylase and lipase) and intestinal enzymes (alkaline phosphatase, aminopeptidase N) were investigated in Kutum (Rutilus frisii Kutum) from the onset of exogenous feeding (3 day after hatching, DAH) to the juvenile stage at 50 DAH. Trypsin- and chymotrypsin-specific activity showed similar patterns and increased with l...
