The effects of substituting dietary protein sources with different levels of Sargassum ilicifolium on growth, survival and body composition of rainbow trout Oncorhynchus mykiss were investigated over the course of a 60 day experiment. A total of 360 juveniles (75±2.8 g) were randomly allotted to four treatment groups including (control: with 100% basal diet (BD); T1: 5% sargassum meal (S...

The reproductive biology of lizard fish Saurida tumbil in the Jizan region of the Red Sea was studied during 1986. Females outnumbered males and attained larger size than males. Among young individuals male s were more numerous than females, while in older age groups the females were more num erous. There is no significant difference in length-weight relation ship between the sexes . The equa t...

an 8-week feeding experiment was carried out on beluga (huso huso) juvenile to evaluate the effects of different levels of fish oil containing n-3 highly unsaturated fatty acids (n-3 hufas) on fish growth and fatty acid composition. the requirements of beluga juvenile for n-3 hufas were studied by feeding fish diets containing six different levels of n-3 hufas ranging from 1.56 to 17.25% (% of ...

In many North American rivers, populations of multiple species of non-native cyprinid fishes are present, including black carp (Mylpharyngodon piceus), grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), common carp (Cyprinus carpio), and goldfish (Carassius auratus). All six of these species are found in the Mississippi Ri...

Accurate prediction of meat yield in live animals may allow more efficient genetic improvement of meat yield in farm-raised catfish. An initial trial with 30 channel catfish demonstrated significant correlations among weight-adjusted residuals for muscle area measured from transverse ultrasound images and transverse sections at five locations along the trunk musculature (r = 0.30 to 0.70). Rela...

The aim of this study was to determine the effect of fish meal and mineral-vitamin premix, supplementing organic diets, on the performance of pigs and some meat and blood characteristics. The experiment was conducted on an organic pig fattening farm. The study involved 120 pigs with an approximate 25 kg body weight. Animals were divided into 3 groups, kept in pens, 10 animals each. Group I (con...

Ahstracr.-This study evaluated the effects of dietary protein concentration (26, 28, and 32%) on growth. feed efficiency, processing yield, and body composition of USDA 103 and Mississippi “normal” (MN) strains of channel catfish raised in ponds. Fingerling channel catfish (average weight = 32.5 and 47.3 g/fish for USDA103 and MN strains, respectively) were stocked into 24 0.04-ha ponds (12 pon...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal science university poultry farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. the chicks were randomly distributed following a completely randomized desig...

Food waste from fish and fruit shops was used as an alternative to the grain in grower-finisher pig diets. Two diets were formulated on an iso-nutrient basis (14 MJ digestible energy per kg, 160 g crude protein per kg on a dry-matter basis) to contain 0 g of food waste per kg in the control diet and 50 g of fish-shop waste per kg and 120 g of fruit-shop waste per kg in the experimental diet. In...
