Utilization of soy flour by fingerling rainbow trout having different body size.

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 dietary energy levels and feeding rates on growth and body composition of fingerling rainbow trout (Oncorhynchus mykiss)

Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...

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...
