Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [ 130 ] [ 131 ] Agricultural Research Service scientists found that 60–90% of nitrogen runoff and 70–100% of phosphorus runoff can be captured from manure effluents using a ...
Laurencia can be found all over the world, in particular in tropical and subtropical regions with warmer waters. [citation needed] Its habitats range from tide pools, reef flats, mud flats, and a variety of hard substrates (e.g. rocks, corals), within intertidal and subtidal zones up to 65 m. [4]
Other brown algae can be found at the low-littoral such as Himanthalia, Laminaria saxatilis and Alaria esculenta. Small green and red algae and animals occur, protected under these large brown algae. [7] When washed up on beaches, kelp flies such as Coelopa pilipes feed and breed on Fucus algae.
This polysaccharide is a major component of brown algae, and is not found in land plants. Alginic acid can also be used in aquaculture. For example, alginic acid enhances the immune system of rainbow trout. Younger fish are more likely to survive when given a diet with alginic acid. [56] Brown algae including kelp beds also fix a significant ...
Valonia ventricosa, also known as bubble algae, sea grape, [2] or sailor's eyeballs, [3] is a species of algae found in oceans throughout the world in tropical and subtropical regions, within the phylum Chlorophyta. It is one of the largest known unicellular organisms. [3] [4] Valonia ventricosa in the Red Sea
Volvox is a genus of freshwater algae found in ponds and ditches, even in shallow puddles. [7] According to Charles Joseph Chamberlain , [ 13 ] "The most favorable place to look for it is in the deeper ponds, lagoons , and ditches which receive an abundance of rain water.
The thick algae on Lake Okeechobee has caused a State of Emergency, keeping the water behind the flood gates and stopping the spread down the rivers and eventually the coast.
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 ...
