WHAT CAN A MILLION OYSTERS DO

As filter feeders, oysters significantly enhance water quality by removing excess nutrients, such as nitrogen and phosphorus, key pollutants in aquatic environments. They achieve this through assimilation and denitrification processes. In assimilation, oysters consume algae, incorporating nutrients into their tissues and shells. Even when not harvested, as in Fort Lauderdale, these oysters play a vital role in reducing nutrient levels by filtering and assimilating these substances.

Oyster reefs create complex structures that enhance marine habitats by providing nooks for fish and invertebrates to hide and thrive, thereby increasing biodiversity. These reefs improve water quality through filtration, removing pollutants and clarifying water, which benefits aquatic plants and supports healthier ecosystems. Additionally, oyster reefs serve as crucial breeding and feeding grounds, bolstering marine life populations.

Oysters help reduce the risk of harmful algal blooms by filtering large volumes of water and consuming algae, including the types that can lead to these blooms. Their natural filtration process removes excess nutrients, such as nitrogen and phosphorus, which are primary fuels for algal overgrowth. By controlling algae levels, oysters maintain balanced ecosystems and prevent the conditions that foster harmful blooms.
