The species most commonly claimed to be capable of producing this kind of toxicity include several species from the genus Kyphosus, including Kyphosus fuscus, K. cinerascens, and K. vaigiensis. [1] It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet, but a dietary origin may be more likely.
Oil pollution toxicity to marine fish has been observed from oil spills such as the Exxon Valdez disaster, and from nonpoint sources, such as surface runoff, which is the largest source of oil pollution in marine waters. Crude oil entering waterways from spills or runoff contain polycyclic aromatic hydrocarbons (PAHs), the most toxic components ...
They may induce hallucinogenic effects similar to LSD (lysergic acid diethylamide) if eaten. [5] However, based on the reports of exposure they are more likely to resemble hallucinogenic effects of deliriants than the effects of serotonergic psychedelics such as LSD. In 2006, two men who apparently ate the fish experienced hallucinations ...
To illustrate the amounts of EPA and DHA in supplements, a softgel capsule containing fish oil derived from pollock might contain a total of 642 mg of total fish oil, of which 584 mg are omega−3 fatty acids, with 377 mg EPA and 158 mg DHA. 3 That same company's salmon oil softgel contains 1008 mg of total fish oil, of which 295 mg are omega ...
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.

Oil is "acutely lethal" to fish - that is, it kills fish quickly, at a concentration of 4000 parts per million [25] (0.4%). The toxicity of petroleum related products threaten human health. Many compounds found in oil are highly toxic and can cause cancer (carcinogenic) as well as other diseases. [23]
The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. [15] Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea, and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints.
As a result, researchers in the field of toxicology focused on the development of QSAR models as a means of assessing toxic effects of chemicals in fish. [2] In toxicology, the quantitative structure-activity relationship (QSAR) approach is a method for predicting toxicity based on the properties and structure of a toxicant. [3]
