Barley straw, in England, is placed in mesh bags and floated in fish ponds or water gardens to help reduce algal growth without harming pond plants and animals. Barley straw has not been approved by the United States Environmental Protection Agency (EPA) for use as a pesticide and its effectiveness as an algaecide in ponds has produced mixed results during university testing in the United ...
A fish kill in a lake in Estonia in 2002 was attributed to a combination of algae bloom and high temperatures. [15] When people manage algae blooms in fish ponds , it is recommended that treatments be staggered to avoid too much algae dying at once, which may result in a large drop in oxygen content.
Several types of invertebrates are present in the ponds where they control the population of algae, which then settles to the bottom. [15] Heavy algal growth may block sunlight from penetrating into the pond. This decreases the potential for photosynthesis to contribute oxygen to the pond. [citation needed]
An algae scrubber allows algae to grow, but the algae grow inside the filter instead of in the aquarium or pond. This removes excess nutrients (scrubs the water), diminishing nuisance algae in the aquarium or pond . Nuisance algae in the aquarium or pond are not to be confused with the desired algae in the algae scrubber filter itself.
This over-nitrifies the pond water and results in mass algae blooms and local fish kills. Some farm ponds are not used for runoff control but rather for livestock like cattle or buffalo as watering and bathing holes. As mentioned in the use section, ponds are important hotspots for biodiversity.
Gambusia holbrooki has been implicated in the decline of at least 9 fish and 10 native frog species. [7] By consuming algae-eating zooplankton, they increase the chances of algae blooms in the water, reducing the water quality. They are very aggressive, and tend to attack other fish and nip their fins, leading to infection or death. [8]
