effects of different levels of ascorbic acid consisting of 0, 100, 200, 400, 800 and 1600 mg/kg feed were examined on some immune variables of juvenile great sturgeon (huso huso) weighing 38 g at water temperature 20°c for 16 weeks. significant difference were observed in level of lysozyme in fish treated 400 and 1600 mg compared with control group 8 week post-treatment (p0.05) 16 weeks post-tr...

Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have b...

in order to understand the effects of different organic and chemical fertilizer on stigma yield, corm characterstics and leaf dry matter yield (as a forage) of saffron (crocus sativus l.), an experiment was conducted in the research station of faculty of agriculture, ferdowsi university of mashhad, iran, in 2005-2009; as a randomized complete block design with 12 treatments and three replicatio...

Although carp is still widely sold and used in its fresh form, a range of value additions may also be observed. It is essential to know the development and management of a carp farm production costs and their evolution. In Iran, warm-water fish farming is based on common, silver, grass, and bighead carps. The carp is easy to rise in hatcheries in very large numbers at little cost, and is distri...

The experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile Catla catla in the laboratory for 90 days. Fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8L:16D), 16 hours light: 8 hours dark (16L:8D), continuous light (24L:0D) and co...

the aim of this study was to evaluate the effect of mannan oligosaccharide (mos; activemos®) on haematological and biochemical parameters of rainbow trout (oncorhynchus mykiss) juveniles. fish fed during 60 days with a basal diet supplemented with 1, 2.5 and 4 g kg-1 mos. blood samples were collected from caudal vein of 36 apparently healthy fish at the end of trial and data was analysed by reg...
