Study Notes
Toxic Algae and Harmful Algal Blooms (HABs)
- HABs are caused by overgrowth of algae due to eutrophication, leading to oxygen depletion in water bodies.
- Approximately 40 species of phytoplankton produce potent neurotoxins, leading to human poisoning and fish kills.
- The frequency of HABs has increased globally, with natural and man-made causes contributing to their expansion.
- Aquaculture systems are vulnerable to HABs, causing fish death and shellfish poisoning.
- HABs have been detected in the Arctic due to ocean warming and changing environmental conditions.
- Algal blooms occur year-round in Kuwait’s waters, with 77 identified taxa, 30 of which are potentially toxic to humans.
- Kuwait’s coasts have been extensively modified, and the first recorded red tide incident was in May 1997.
- Management considerations for preventing HABs include reducing pollution input, regulating aquaculture facilities, and restricting species introductions.
