An effective way to clear Ich from a fish population is to transfer all of the fish carrying trophonts in their skin, fins or gills to a non-infected tank every 24 hours. Then the fish do not get re-infected and after a number of days (dependent on temperature) the fish have cleared the infection because trophonts exit within this period.
It was discovered that euglonophycin, a euglenoid ichthyotoxin derived from Euglena sanguinea, displays anticancer activity. [4] By sharing a similar chemical structure to solenopsin, an angiogenic inhibitor and alkaloid toxin derived from fire ant venom, euglonophycin has been studied for potential application in natural products and drug development for cancer therapy.

The symptoms and life-cycle are generally similar to those of Ichthyophthirius in freshwater fish, including white spots, on account of which Cryptocaryon is usually called marine ich. However, Cryptocaryon can spend a much longer time encysted. Fish that are infected with Cryptocaryon may have small white spots, nodules, or patches on their ...
The lionfish most likely got its name from the 18 venomous spines that fan out across its body like a lion’s mane. Get stung by one and you could experience pain and swelling, and even paralysis.
A deadly pufferfish hospitalized an entire family who unintentionally consumed the poisonous fish for dinner. According to Brazil's Globo News, eleven members of the Souza family ate a pufferfish ...
When large numbers of fish, like shoaling forage fish, are in confined situations such as shallow bays, the excretions from the fish encourage this dinoflagellate, which is not normally toxic, to produce free-swimming zoospores. If the fish remain in the area, continuing to provide nourishment, then the zoospores start secreting a neurotoxin ...
“A deal breaker, on the other hand, is a fundamental incompatibility. Like, I have asthma and if you’re a smoker, this isn’t going to work.”
The extremely toxic (to humans), tropane alkaloid-containing shrub Latua pubiflora (family Solanaceae) was used formerly by the Huilliche people of the Los Lagos Region of southern Chile to catch fish in slow-flowing rivers - either alone or in combination with the juice of Drimys winteri (Winteraceae) - the latter being a fish poison in its ...
