Are marbled crayfish aka Marmorkrebs edible?

* They are an invasive species: Marbled crayfish are known for their rapid reproduction and ability to outcompete native species. Eating them won't solve the problem, and may even encourage their spread through accidental release of eggs or juveniles.

* They are not commercially raised: They are not bred for consumption like other crayfish species. Therefore, there is no established food safety or quality control.

* Potential for toxins: While not proven, there is a chance that they could accumulate toxins from the environment, particularly in areas where water quality is poor.

It's important to remember that eating invasive species can have negative consequences for the environment and could pose a risk to your health. If you find yourself with marbled crayfish, the best course of action is to dispose of them responsibly and report them to the appropriate authorities.
