Adult triploids in a rainbow trout family.
نویسندگان
چکیده
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. XXY triploids were males, suggesting that the Y chromosome is male determining in trout. Because they may avoid production losses associated with sexual maturation in normal fish, triploid trout and salmon could potentially be useful in fish culture.

Acute stress response in triploid rainbow trout
The purpose of this study was to determine whether triploid salmonid fishes differ from diploids in their hematological and physiological responses to an acute handling and confinement stress, induced by netting fish from their tanks and placing them in a bucket. Blood samples were Ž . collected from fish prior to the handling stress and at either 30 min rainbow trout or 20 and 40 Ž . min brook...
متن کاملPloidy effects on genes regulating growth mechanisms during fasting and refeeding in juvenile rainbow trout (Oncorhynchus mykiss).
Diploid and triploid rainbow trout weighing approximately 3g were either fed for five weeks, or feed deprived for one week, followed by refeeding. During feed deprivation gastrointestinal somatic index decreased in diploids, but not triploids, and during refeeding, carcass growth rate recovered more quickly in triploids. Although not affected by ploidy, liver ghr2 and igfbp2b expression increas...
متن کاملEffect of age on reproductive efficiency of adult rainbow trout, Oncorhynchus mykiss Walbaum, 1972
Rainbow trout, oncorhynchus mykiss is one of the most important cold water fishes in Iran. For successful artificial propagation of rainbow trout, the quality and quantity of brooders and sexual materials are key factors. In the present study, we investigated the age-dependent changes of reproductive efficiency. For this purpose, the brooders were divided into age classes and then three age gro...

متن کاملExperimental evaluation of rainbow trout Oncorhynchus mykiss predation on longnose dace Rhinichthys cataractae
Laboratory and in-stream enclosure experiments were used to determine whether rainbow trout Oncorhynchus mykiss influence survival of longnose dace Rhinichthys cataractae. In the laboratory, adult rainbow trout preyed on longnose dace in 42% of trials and juvenile rainbow trout did not prey on longnose dace during the first 6 h after rainbow trout introduction. Survival of longnose dace did not...
