What causes microalgal blooms and why are they dangerous?
Microalgal blooms are often triggered by unusual weather conditions, such as high temperatures and stagnant water. These conditions can lead to rapid algae growth, which can produce toxins harmful to both humans and marine life. The recent bloom in South Australia has resulted in health issues for beachgoers, including coughing and sore throats, and has caused significant fish mortality.

What can be done to prevent future blooms?
Preventing future microalgal blooms involves addressing environmental factors such as nutrient runoff and water temperature. Implementing better land management practices, reducing pollution, and monitoring water quality can help mitigate the conditions that lead to these harmful blooms.
-
What are the long-term effects of microalgal blooms on marine life?
Microalgal blooms can have devastating long-term effects on marine ecosystems. The toxins produced can lead to fish kills and disrupt the food chain, affecting not only fish but also other marine organisms and the overall health of the aquatic environment.
