this study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. experimental diets consisted of 30.3% protein, 18.7 kjg-1 energy and 16.7% lipid from fish oil (fo), canola oil...

fish is one of the healthy foods and a rich source of animal protein average household consumption of fish in our soceity is such a low in that one can rarly find it in a family food basket. therefore, this study aimed at analyzing the factors affecting consumption of fish among tabrizian households. to do this, a total of 224 questionnaires was conducted using clustered two- stage sampling met...

the present study was aimed to assess the influence of brown marine algae and vitamin e (ve) (160 ppm α-tocopheryl acetate) on stability of chicken meat enriched with fish oil. in this study, 360 d-old broilers (arbor acres plus) were randomly assigned to 6 treatment groups with 4 replicates of 15 birds in each. experimental groups consisted of corn-soybean basal diet (c), corn-soybean basal di...

parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. in this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: goldfish (carassius auratus), guppy (poecilia reticulate), angelfish (pterophyllum scalare), discus (symphsodon discus) and sailfin mollies (poecilia latipinna) was obtained from a l...

since its first clinical application in early 90s, preimplantation genetic diagnosis (pgd) has became a powerful diagnostic procedure in clinical practice for avoiding the birth of an affected child as well as increasing the assisted reproductive technologies (art) outcome . the technique involves the screening of preimplantation embryos for chromosomal abnormalities in certain indications such...

the effectiveness of pituitary extract from crucian carp (carassius auratus linnaes 1758) in inducing ovulation in veil tail gold fish (carassius auratus gibelio bloch 1783), was examined and the effect of maternal hormone treatment on egg quality in two types of fertilization (fertilization in aquarium and artificial fertilization), were evaluated in 22·c temperature. fish were injected intrap...

This paper describes the first determination of water-escape velocities in free-ranging sharks. Two approximations are used to estimate the final swimming speed at the moment of penetrating the water surface. Blacktip sharks were videotaped from below the surface and parameters were estimated by analysing the sequences frame by frame. Water-escape velocities averaged 6.3 ms(-1). These velocitie...
