Impact of dietary phosphorus on turbot bone mineral density and content

Fish are largely dependent on dietary phosphorus for skeletal development and mineralization. In aquaculture, commercial diets commonly have higher concentration than the basal requirements in most fish species to ensure growth prevent bone mineral disorders. Excessive feeds is harmful metabolism results an increase of wastes farm effluents, which impact aquatic ecosystems. Previous studies shown that depletion/excess cause malformations reduced/enhanced mineralization fish. There scarce information optimal with different types (cellular vs. acellular bone), particularly relevant sustainable aquaculture. Thus, aim our study was analyse effect concentrations turbot, a demersal acellular-boned valuable aquaculture species. Our show did not changes density phosphate/calcium concentrations. No apparent were detected. Additionally, we find altered expression genes involved metabolism. Taken together, data optimum turbot below those currently used commercially at least time period examined: 55–195 days postfertilization (dpf).
