And this types of feed called natural fish feed. produces 50–55% of fish feed ingredients of making fish feed, with the remainder imported. To reduce the production of solanines and chaconine it is important to store potatoes in a dark, cool and dry place, and not to eat green or sprouting parts. Adverse health effects can be acute poisoning ranging from allergic reactions to severe stomachache and diarrhoea, and even death. Natural Toxins in Fish Other Than Molluscan Shellfish. Under typical fish-pond conditions, the measured FCR of supplementary feeds will also change in the course of production seasons. The outcome of such health risk assessments can either be a maximum tolerable intake (exposure) level, or other guidance to indicate the level of health concern (such as the Margin of Exposure), including advice on risk management measures to prevent and control contamination, and on the analytical methods and monitoring and control activities.
