Growth and Muscle Quality of Grass Carp (Ctenopharyngodon idella) in In-Pond Raceway Aquaculture and Traditional Pond Culture

In-pond raceway aquaculture (IPRA) is the rational prescription for water eutrophication and improves pond environment, enhancing production quality of fish. This experiment explored growth performances muscle grass carp with stocking densities 32 tail/m3 0.07 tail/m2 in IPRA traditional culture (TPC), respectively. The hepatosomatic index, visceral mass ratio, correction factor were statistically similar compared to TPC. While weight gain rate (p < 0.001) content crude lipid 0.05) flesh observed be promising IPRA, pH holding capacity, as well hardness chewiness, not significantly different between two systems. However, 2-MIB concentration was increase continuously complete period IPRA. abundance Proteobacteria found higher TPC 0.05), while richness Planctomycetes superior 0.05). Despite high density, off-flavor IPRA-produced had less an impact on aesthetic Considering all these facts, results this study show that a better can produced from
