Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, mechanical damage to other organisms, or by other means.
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. [1] The term algae encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like ...

Boucek figured the exposure was likely from the water, and when he removed spinning fish from the ocean and placed them in tanks with clean water, some recovered in as little as 25 minutes.
Grubbs and Florida researchers studying the fish have tagged over 100 to track their movements and found sawfish are typically found in deeper water, up to 200 feet deep, in January and February.
Lake George, New York, an oligotrophic lake. The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. [1] Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale ...
Scientists are baffled as to why the rare and endangered sawfish have been spotted in Florida waters spinning around, and 28 have been found dead. These Florida fish are spinning, acting ...
An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms — aquatic life —that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. [1]
