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.
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 ...
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 ...
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.

Blooms have been noted to occur as far north as North Carolina and are commonly seen alongside the widespread death of fish and sea birds. [4] In addition to the effects on human health, the economic impact of HAB-associated shellfish toxin outbreaks can have significant economic implications as well due to not only the associated healthcare ...
Fish are impacted by the oil that is taken in by their gills and digestive system. [4] Many species of shellfish can survive exposure to oil, but accumulate high levels in containment in their bodies. [4] Oil in water can contaminate algae, plankton, and fish eggs, which in turn contaminate fish that feed on them. [4]
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 ...
Similar symptoms and effects of the PCBs and PCDFs were shown, especially in children. [6] There have been studies undertaken on animals to understand the mechanisms of PCBs and PCDFs and their effects. [1] Scientists discovered that low levels of PCBs could kill fish and other wildlife and as such their use in manufacturing was reduced. [7]
