Skeletal Anomaly Monitoring in Rainbow Trout (Oncorhynchus mykiss, Walbaum 1792) Reared under Different Conditions

摘要: The incidence of skeletal anomalies could be used as an indicator the “quality” rearing conditions these are thought to result from inability homeostatic mechanisms compensate for environmentally-induced stress and/or altered genetic factors. Identification that lower rate can important step toward profitable aquaculture malformed market-size fish have discarded, thus reducing farmers’ profits. In this study, occurrence in adult rainbow trout grown under intensive and organic was monitored. As animal production is its early stages, broodstock not available sufficient quantities. Non-organic juveniles could, therefore, on-growing purposes cycle. Thus, analysed study experienced during juvenile rearing. Significant differences pattern were detected between organically intensively-ongrown specimens, although severe, commercially anomalies, affecting 2–12.5% individuals, comparable two systems. needs improved order significantly reduce severe trout.
