Evaluation of the net energy value of glucose (cerelose) and maize starch in diets for rainbow trout (Salmo gairdneri).
1. Quadruplicate groups of rainbow trout (Salmo gairdneri) (mean body-weight 24.9 g) were reared on six dietary treatments (practical-type diets) in a modified paired-feeding experiment for 12 weeks at 15 degrees to determine the net energy (NE) value of starch and glucose to rainbow trout. 2. Three test diets were prepared to contain (g/kg): 0 supplemented carbohydrate (diet 1), 250 maize star...
متن کاملAdult triploids in a rainbow trout family.
Six triploid individuals were found in a full-sib family of 11 adult rainbow trout (Salmo gairdneri) from a domesticated hatchery stock. The triploid individuals were normal in size and external appearance, had underdeveloped gonads, and showed no evidence of 3n/2n chimerism or mosaicism.

been reported in fish, all of them in trout (924,34, 47). In 1955 a high incidence of hepatic tumors was found in rainbow trout in Italian hatcheries (9). Interest in these neoplasms was renewed recently when hepatic tumors were discovered in large numbers of hatchery-reared rainbow trout in the United States (928,35, 592,61, 64), Italy (920), and France (3, 30). The main varieties of tumors th...
متن کاملResponse 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...
