However, total elimination of algae is considered unlikely in a hobby aquarium. Algae can be used as an bioindicator to inform an aquarist on water chemistry and other conditions. [2] Some species are intentionally cultivated within algae scrubbers. Few algae, such as marimo or red moss, are sought after for aquascaping in freshwater aquaria.
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 ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
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, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
A close up of microalgae – Pavlova sp. An algae bioreactor is used for cultivating micro or macroalgae. Algae may be cultivated for the purposes of biomass production (as in a seaweed cultivator), wastewater treatment, CO 2 fixation, or aquarium/pond filtration in the form of an algae scrubber. [1]
Algae constitute a polyphyletic group since they do not include a common ancestor, and although their chlorophyll-bearing plastids seem to have a single origin (from symbiogenesis with cyanobacteria), they were acquired in different ways. Green algae are a prominent example of algae that have primary chloroplasts derived from endosymbiont ...
It includes about all types of algae, [4] as well as one group of flowering plants, the sea-grasses. [1] Information about each species' taxonomy , nomenclature and distribution is included, and the algae covered include terrestrial as well as marine and freshwater species, such as seaweeds , phytoplankton , and freshwater algae.
Coelastrum is a genus of green algae in the Scenedesmaceae family. It is a common component of the phytoplankton in freshwater habitats such as ponds, lakes, waterfalls, and temporary pools of water, [1] particularly eutrophic ones. [2]
