Ichthyotoxin
Ichthyotoxins are compounds which are either toxic to fish or are toxins produced by fish. The toxins can be found in gar eggs and the eggs of several other species' roe. It can also be found in some species of algae such as prymnesium parvum. They include euglenophycin and prymnesins, made by algae and can cause large-scale fish deaths, and ostracitoxin made by boxfish. Many toxin producing algal species can be found both in marine and fresh water environments when the algae is in bloom. The toxin is protein based and is poisonous to humans, small mammals, and some fish. An ichthyotoxic poisoning can cause symptoms ranging in severity dependent on how much toxin was consumed. The symptoms of an ichthyotoxin poisoning can include headache, vomiting, diarrhea, dizziness, drop in blood pressure, and many others.
