Why is it a problem?
Complicated Life Cycle
In their social media post, the United States Fish and Wildlife Service warned anglers about a potential parasite hitching a ride on fish of many different species. The problem is complex, involving multiple hosts and a lengthy cycle. To summarize:
- A fish-eating bird poops flatworm eggs into the water.
- Snails pick up the eggs and become infected.
- The parasite then escapes the snail, swims around, and burrows into a fish’s skin.
- The fish gets eaten by another bird, and the cycle starts all over again.
This cycle can be difficult to track, making it challenging for anglers to identify the problem.
Identifying the Problem
Black Dot Warning
The FWS urged anyone catching fish with the intent to eat them to keep an eye out for small black dots. These dots are a sign of flatworms, which embed themselves under the animal’s skin.
“The black spots are a sign of flatworms, who embed themselves under the animal’s skin. The cycle that leads to this phenomenon is quite complicated, involving multiple hosts and a lengthy cycle.”
In fact, the FWS describes the condition as “gross”, but also provides good news about how to deal with the potential parasites.
What to Do with Infected Fish
Cooking to Safety
Fortunately, high heat kills flatworms, making it safe to eat affected fish if properly cooked. The official recommendation is a minimum of 145 degrees Fahrenheit. However, many anglers might choose to release their catch instead, especially if they don’t want to deal with the potential parasites.
| Method | Temperature | Effectiveness |
|---|---|---|
| Cooking | 145°F (63°C) | Safe to eat |
| Chilling | 39°F (4°C) | Flatworms can survive |
| Freezing | -4°F (-20°C) | Flatworms die |
Supporting the Fishing Season
Local Organizations
In New York, local organizations like the New York State Department of Environmental Conservation help support the fishing season with everything from licenses to stocking local waters with their “fishmobile”. Check out their offered free fishing days below.

Conclusion
Be Aware
Anglers should be aware of the potential parasites hitching a ride on fish, especially if they plan to eat them. By identifying the problem and taking the necessary precautions, anglers can enjoy a safe and successful fishing season.
