  • Hunting and Fishing During Harmful Algal Blooms

    Can I Eat Fish from Waters Experiencing a Harmful Algal Bloom (HAB)? Toxins can accumulate in fish in waters experiencing a HAB. The highest concentrations are in the organs, particularly the liver, and fat deposits. Muscle tissue typically has lower toxin levels. Fish taken from waters with intermittent blooms are unlikely to have toxin levels…
