Effect of Altering Dietary Protein: Energy Ratios on Juvenile Pallid Sturgeon Growth Performance
Pallid Sturgeon Scaphirhynchus albus are endemic to the large, freshwater, river systems of North America and have long been prized for caviar production. Declining wild populations and fishing prohibitions have created interest in the culture of these fish. Protein and energy are often the first nutrients examined when attempting to identify diets appropriate for a novel culture species. There...
متن کاملCritical Swimming Speed and Behavior of Juvenile Shovelnose Sturgeon and Pallid Sturgeon
The swimming performance of hatchery-reared. juvenile shovelnose sturgeon Scaphirhynchus plarorynchus and pallld sturgeon S. albus was studied in a laboratory swim tunnel at 20°C and 1O0C. The mean 30-min critical swimming speed was not significantly different between species at either temperature (36.9 crd s for shovelnose sturgeon and 35.9 cm/s for pallid utur-geon at 20°C. 19.4 cmls for shov...
متن کاملGrowth performance and blood indices of juvenile Rainbow trout (Onchorhynchus mykiss) fed diets containing Sargassum cristaefolium and Gracilaria pygmaea extracts
this experiment was carried out to investigate the effects of supplementing two macroalgae Sargassum cristaefolium and Gracilaria pygmaea extracts in feed on some growth indices, hematology and blood constituents of juvenile rainbow trout (Onchorhynchus mykiss). Rainbow trout were randomly divided into four groups: a control group was fed with basal diet, and three treated groups fed with basal...
متن کاملFood Consumption and Growth of Juvenile Arrowtooth Flounders
Food consumption and growth of juvenile arrowtooth flounders Atheresthes stomias were examined in the laboratory. Weight gain, Y (in % BW/d) was related linearly to food consumption, X (in J/g/d): Y = 0.0033X 0.0564; r 2 = 0.75 at 4°C. Fish 30 to 300 g had similar energy conversion efficiencies. When fed Pacific herring Clupea pallasi at 4°C, maintenance ration was estimated to be 17 J/g/d. Min...
متن کاملGrowth performance and immune response of broiler chickens fed diets supplemented with probiotic and (or) prebiotic preparations
The objective of this research was to investigate the efficacy of dietary inclusion of probiotics Primalac® and Bactocell® and prebiotic Fermacto® on broiler’s performance and immune response, individually or in combination. A total of 540 one-d-old male Ross 308 broiler chicks were allocated into 6 experimental treatments with 6 replicates of 15 birds per replicate from 1 to 42 d of age. The b...
