Effect of thermal stress on some hematological parameters of diploid and triploid Rainbow trout (Oncorhynchus mykiss)
Temperature fluctuation is one of the most common stressors during fish transportation and aquaculture condition. Triploid rainbow trout (Oncorhynchus mykiss) get more attention because of its sterility. In this study, 24 rainbow trout belong to diploid and triploid group, average weight 13±0.23 g were subjected to temperature change from 13 to 20 ºC, and kept under tension for 10 min. Before a...
متن کاملFlesh characteristics of pan-size triploid and diploid rainbow trout (Oncorhynchus mykiss) reared in a commercial fish farm
Sexual maturation of rainbow trout during production has a negative effect on the slaughter yields and flesh quality. Induction of triploidy is a method to prevent the development of fertile trout. In many investigations sexually mature triploid and diploid rainbow trout had been compared. In the present study the slaughter characteristics and flesh quality of female immature diploid and triplo...
متن کاملبررسی امکان تولید جمعیت تمام ماده تریپلوئید قزلآلای رنگینکمان (Oncorhynchus mykiss)
In order to reduce the adverse effects of sexual maturation on growth and survival of rainbow trout, production possibility of all-female triploid was investigated by means of early heat shock on eggs fertilized by masculinized male’s sperm. Fish ploidy level was determined by erythrocyte size measurement and confirmed by gill nucleolus (NORs) counting as well as chromosome number. Sexual ratio...
