Red tide

Definition

Red tide is a harmful algal bloom caused by the proliferation of certain algae, particularly dinoflagellates. These blooms can produce toxins that are detrimental to marine life and humans.

5 Must Know Facts For Your Next Test

1. Red tides are often caused by dinoflagellates like Karenia brevis.
2. The toxins produced during red tides can contaminate shellfish, leading to food poisoning if consumed by humans.
3. Environmental factors such as nutrient pollution and warm water temperatures can contribute to the occurrence of red tides.
4. Red tides can cause massive fish kills due to oxygen depletion and toxin production in the water.
5. Monitoring and management strategies are essential to mitigate the impacts of red tides on public health and marine ecosystems.
