Review of Wildlife Health Outcomes and Potentially Toxic Algal Blooms in the Chesapeake Bay Active

Chesapeake Bay's Algae Blooms Raise Concerns

Wildlife Health Impacted by Algal Blooms

The Chesapeake Bay Program is actively monitoring potentially toxic algal blooms in the Chesapeake Bay. In late August, the Bay is experiencing prime time for algae blooms, and wildlife health outcomes are being closely observed.

In the summer months, the water temperature in the Bay rises, creating ideal conditions for algae growth. Some types of algae can produce toxins that are harmful to fish, shellfish, and other wildlife. These toxins can cause a range of health problems, including respiratory distress, liver damage, and neurological disorders.

In recent years, there have been several reports of wildlife deaths associated with algal blooms in the Chesapeake Bay. In 2019, a large bloom of the algae Karenia brevis caused the death of thousands of fish in the Bay. In 2020, a bloom of the algae Pseudo-nitzschia australis caused respiratory distress in several dolphins.

Monitoring and Mitigation Efforts

The Chesapeake Bay Program is working to monitor and mitigate the impacts of algal blooms on wildlife health. The program conducts regular water quality monitoring to track the presence of harmful algae. The program also works with partners to develop and implement strategies to reduce nutrient pollution, which can contribute to algal blooms.

Conclusion

Algal blooms are a serious threat to wildlife health in the Chesapeake Bay. The Chesapeake Bay Program is working to monitor and mitigate the impacts of algal blooms, but more needs to be done to address the underlying causes of these blooms. By reducing nutrient pollution and taking other steps to improve water quality, we can help to protect wildlife and ensure the health of the Chesapeake Bay ecosystem.
