Harmful Algal Blooms

Most algal blooms are not harmful, but some produce toxins. These are known as Harmful Algal Blooms (HABs).

Toxicity: Some algal blooms when died or eaten, release neuro & hepatotoxins which can kill aquatic organism & pose a threat to humans. E.g. Shellfish poisoning.

HAB events adversely affect commercial and recreational fishing, tourism, and valued habitats, creating a significant impact on local economies and the livelihood of coastal residents.
