Eating your catch - making healthy choices

Fishing Wisconsin

Baked fish

Eating your catch can be part of a healthy, balanced diet. Fish are generally low in unhealthy saturated fats and high in protein. Fish contain vitamins and minerals and are the primary food source for healthy omega-3 fats.  Studies suggest that omega-3 fats may be beneficial during the fetal brain and eye development, and eating modest amounts of fish containing these healthy fats may lower the risk of heart disease in adults.  Health experts recommend that fish be included as part of a healthy diet.

However, fish may take in pollutants from their environment and food.  Mercury, PCBs, and PFAS are the contaminants of most significant concern in fish, prompting recommendations that people limit or avoid eating certain fish species from many waters throughout the nation. You can get the health benefits of eating Wisconsin's fish while reducing potential health risks from unwanted pollutants by following Wisconsin’s fish consumption guidelines.

Compare the type of fish and where you caught your fish with the consumption advice. After consulting the recommendations, you may find that you do not have to change your eating habits, you may choose to eat different types of fish or eat some species less frequently.
