摘要: Abstract Two trials evaluated winter feeding strategies for small golden shiners, Notemigonus crysoleucas destined the crappie, Po-moxis spp. market. Fish were stocked at 615 g/pool (approximately 127 or 158 fish/m2, 1 and 2, respectively) in aerated, 5.9-m2 pools 100 104 days, respectively. In first trial, fish fed a commercially available 32% crude protein crumbled, extruded pellet once daily rates of 0% (fertilizer only), 1%, 2% body weight/day (bw/d) on days when afternoon air temperature was >7°C. Unfed lost weight, their condition declined. 1% maintained both weight condition, while gained weight. second trial bw/d those either >7°C >10°C, with sinking (compressed). crumbles significantly better harvest than pellet, re...
