dc.description.abstractA 10-week feeding trial in a recirculation rearing system was conducted to investigate the effects of dietary soy protein concentrate (SPC) levels on survival, growth, digestion, and protein metabolism of juvenile darkbarbel catfish Pelteobagrus vachelli. The results demonstrated that survival and whole-body composition were independent of dietary treatments. Feed intake (FI), specific growth rate (SGR), feed conversion ratio (FCR), apparent digestibility coefficients, digestive enzymes (pepsin and trypsin) activity and protein metabolism enzymes (alanine aminotransferases) decreased with increasing dietary SPC. The diet with 60% SPC was least cost effective. Results suggest that SPC could replace 60% or less fish meal protein without negatively influencing the growth of juvenile Pelteobagrus vachelli.
