this research was conducted to evaluate alteration of growth performance, nutrition, carcass and some serum biochemical parameters of common carp fed the diets supplemented by different levels of meal and alcoholic extract of alfalfa (medicago sativa). in this research, 300 fish (mean weight: 20.4 ± 0.19 g and mean length: 11.78 ± 0.64 cm) were fed by nine nutritional diets for 8 weeks. nutriti...

in this study, the effects of dietary intake of different levels of ginger (zingiberofficinale) extract on fingerlings of mesopotamichthys sharpeyi,were investigated. for this purpose, 192 fingerlings (mean weight: 11.67±0.32 g) were randomly distributed in twelve 300 litres fiberglass tanks (16 fish per tank) and fed with commercial diet containing 0% (control group),0.1%, 0. 5% and 1% of etha...

The aim of the present study was to evaluate the effect of diets rich in n-6 and n-3 fatty acids on adipose tissue metabolism. Starting at weaning, male Wistar rats were fed ad libitum, for 8 weeks with one of the following diets: C, rat chow; S, rat chow containing 15 % (w/w) soyabean oil; F, rat chow containing 15 % (w/w) fish oil; SF, rat chow containing 15 % (w/w) soyabean and fish oil (5:1...

A completely randomized design, with 3×3 factorial arrangement, was conducted to test various ratios of dietary protein to energy (P/E) for rainbow trout, reared in brackish water. Three crude protein levels (35, 40 and 45%) and three energy levels (370, 400 and 430 Kcal/100g) at each protein level were utilized. Semi-purified diet containing fish meal, casein and gelatin as the sources o...

Mitigation activities designed to supplement nutrient and organic matter inputs to streams experiencing decline or loss of Pacific salmon typically presuppose that an important pathway by which salmon nutrients are moved to fish (anadromous and/or resident) is via nutrient incorporation by biofilms and subsequent bottom-up stimulation of biofilm production, which is nutrient-limited in many eco...

This study evaluated the effect of the consumption of different levels and sources of lipids on metabolic parameters of Wistar rats. Animals were fed with high-fat diet (HFD) containing 20% of lard for 12 weeks to cause metabolic obesity. Subsequently, the animals were divided into six groups and were fed diets with lipid concentrations of 5% or 20% of lard (LD), soybean oil (SO) or fish oil (F...

Salmon carcasses were recorded during October December along spawning streams in 3 study areas: 1 upper Shee Water, R. Tay system (2000 & 2001); 2. Upper Clunie Water, Aberdeenshire Dee system (2000 [part of area] and 2001) and 3. Kinlochewe River, R. Ewe system (2001 only). Estimates of numbers of salmon within each study area are based on fish observations, redd counts and counts at fish trap...

sesame oil cake (ssc) was bio-processed through solid state fermentation (ssf) under optimized conditions by a phytase-producing fish gut bacterium, bacillus subtilis subsp. subtilis (jx292128). ssf significantly reduced anti-nutritional factors (e.g., phytic acid, tannins and trypsin inhibitor) and crude fibre, while enhanced free amino acids, fatty acids and different minerals. phytase product...

Cattle hoof meal was processed by autoclaving, fermentation, wood ash soda treatment and rawunprocessed hoof. This studied on Clarias gariepinus juveniles 14.22±0.23g stocked at 15 fish per tank in replicate. Treated samples were used compounding six isonitrogenous diets of a reference diet 70%: test 30% fed 3% body weight. Significant difference (P<0.05) observed among dietary treatments. W...
