Two synthetic pyrethroid pesticides, α-cypermethrin and deltamethrin were investigated as potential toxic contaminants. The acute and chronic bioassays were conducted using Ceriodaphnia dubia. The toxicity of α-cypermethrin and deltamethrin to C. dubia increased with increasing concentrations and exposure time. C. dubia was three times more sensitive to(More)
We evaluated the effect of dietary protein and lipid on growth and body composition in juvenile red swamp crayfish (Procambarus clarkii). Nine groups of crayfish were fed nine experimental diets containing three levels of protein (24, 27, and 30 %) and three levels of lipid (4, 7, and 10 %) for 8 weeks. We used a 3 × 3 factorial model with four replicates(More)
In this study, growth performance, apparent digestibility coefficients, phosphorus and nitrogen excretion were determined in red swamp crayfish (Procambarus clarkii) (5.39 ± 0.12 g) for four soybean products: soybean meal (SBM), soybean meal diets supplemented with 1000 IU/kg phytase (SBM + P), extruded soybean meal (ESBM) and fermented soybean meal (FSBM).(More)
