متن کاملEffect of male age in Caspian brown trout, Salmo trutta broodstock on reproductive performance
In this study, three different age groups of male broodstocks (4, 5 and 6 years respectively) were used to fertilize eggs obtained from nine females. The results showed that 6 year old males had maximum body weight (1766 g), total length (56.3 cm) and sperm volume (31.83 ml). Results did not show significant difference in spermatocrit and spermatozoa concentration among age groups (p>0.05). Our...

متن کاملEffect of fish meal replacement with Spirulina Spirulina platensis on hematite-biochemical and immune response of Caspian brown trout (Salmo trutta caspius) juveniles
In this experiment, the effect of dietary Spirulina platensis on haemato-biochemical and immunity responses of Caspian brown trout (Salmo trutta caspious) juveniles was investigated. For this purpose, diets with five S. Platensis inclusion levels (control 0%, 2 %, 4%, 6% and 8% of diet fish meal) were prepared. Six hundred juveniles with an average initial weight of 11 ± 1.0 g were assigned to ...
