Utilization of Malt Protein Flour in Fingerling Rainbow Trout Diets

Nocardial Infection in Hatchery-reared Fingerling Rainbow Trout (salmo Gairdneri).

Effects of feeding levels on growth performance, feed utilization, body composition, energy and protein maintenance requirement of fingerling, rainbow trout, Oncorhynchus mykiss (Walbaum 1792)

A 10-week feeding experiment was conducted to evaluate the effects of feeding level, energy and protein maintenance requirement of rainbow trout, Oncorhynchus mykiss, fingerling (5.65±0.45cm; 1.42 ±0.25g) by feeding casein-gelatin based purified diet (45% CP; 3.67 kcal  g-1 GE) at six feeding levels 2-7% of BW/day in two equal meals, at 0800 and 1700 h, in triplicate, with 20 fish per trough fi...

Effect of Fish Meal Replacement with Aqupro on Nutrition and Blood Indices in Fingerling Rainbow trout

The current study was carries out to determine the effect of fish meal replacement with Aqupro on growth, blood indices and liver enzymes activities in fingerling rainbow trout. Number of 540 fish (18 g) were randomly distributed in 18 fiberglass tanks (250 l capacity) and five isoproteic diets were formulated. The fish meal inclusion reduced from 50 percent in diet one to 10 percent in diet fi...

Response of rainbow trout (Salmo gairdneri) to increased levels of available carbohydrate in practical trout diets.

1. The physiological response of rainbow trout (Salmo gairdneri) reared on different levels of available carbohydrate in practical trout diets having the same levels of energy and nitrogen for 16-24 weeks was determined. 2. Weight gain was significantly reduced in trout reared on the highest level of available carbohydrate, 210 g cerelose (alpha-glucose) kg, and there was a significant linear r...

Substrate utilization during graded aerobic exercise in rainbow trout.

A biochemical approach was employed to examine the oxidative utilization of carbohydrate and lipid in red muscle of rainbow trout (Oncorhynchus mykiss) during sustained swimming at 30 and 60% of their critical swimming speed (U(crit); for 2, 15 and 240 min) and during non-sustainable swimming at 90% U(crit) (for 2, 15 and 45 min). Measurements included pyruvate dehydrogenase (PDH) activity, cre...
