the effect of vitamin c on fatty acid compositionof caspian brown trout (salmo trutta caspius) fry
Authors
abstract
the objective of this study was to evaluate the effect of five dosage of vitamin c (0, 50, 250, 750 and 1500 mg vitamin c per kg diet) on fatty acid composition of caspian brown trout fry (salmo trutta caspius). fish (initial average body weight of 0.1 ± 0.02 g) were fed by formulated diets for 6 weeks in triplicate. the findings of growth parameters and survival showed significant difference among groups (p< 0.05). the lowest amount of sgr, bwg and survival was observed in control group while the group of 750 mg/kg had the highest amount of sgr, bwg and survival than those from others.the results showed that fish fed 750 mg/kg diet had a higher pufa, hufa, n-3 and n-6 fatty acids than those from other groups without significantdifference (p > 0.05). control treatment had a lower amount of pufa, hufa, n-3 and n-6 fatty acids than those from other treatments without significant (p>0.05). the sfa fatty acids had a higher amount in 1500 mg/kg diet than those from others without significant difference (p > 0.05). these results showed that vitamins c could be have an important role in protection of fatty acids against oxidation.

full textThe growth of brown trout (Salmo trutta Linn.); factors influencing the growth of trout fry.
It has long been known that brown trout (Salmo trutta Linn.) grow to different sizes in different waters, and there has been much speculation concerning the factors determining these differences. Dahl (1918-19) suggested that the food supply and the degree of crowding were important; also that small, slowly growing trout were derived from smaller ova than those growing more rapidly. Southern (1...
full textEffect of age on reproductive performance in female Caspian brown trout (Salmo trutta caspious, Kessler 1877)
Caspian brown trout (Salmo trutta caspius) is one of the economically valuable species in the Caspian Sea. Artificial propagation and production of larvae are the main problems in the early culture of this species. The purpose of this paper is to study the effect of reproductive performance of female broods on opposition reproduction efficiency in Caspian brown trout in the breeding season of 2...

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...

The maintenance of the endangered Caspian brown trout Salmo trutta caspius populations in Iran depends on its artificial breeding. There is no information on how current hatchery breeding protocol influences effective population size of breeders (Ne), which is a critical parameter to maintain genetic diversity in future generations. The current hatchery protocol (CHP) was comparatively evaluate...
