  2. Algal bloom - Wikipedia

    en.wikipedia.org/wiki/Algal_bloom

    When phosphates are introduced into water systems, higher concentrations cause increased growth of algae and plants. Algae tend to grow very quickly under high nutrient availability, but each alga is short-lived, and the result is a high concentration of dead organic matter which starts to decompose.

  3. Hypoxia in fish - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_in_fish

    A key adaptation to long-term survival during hypoxia is the ability of an organism to store large amounts of glycogen. Many hypoxia-tolerant species, such as carp, goldfish, killifish , and oscar contain the largest glycogen content (300-2000 μmol glocosyl units/g) in their tissue compared to hypoxia-sensitive fish, such as rainbow trout ...

  4. Feed phosphates - Wikipedia

    en.wikipedia.org/wiki/Feed_phosphates

    The majority of the inorganic feed phosphates used in the EU and worldwide are calcium phosphates in different forms (mono-, di- and monodi-calcium phosphates) but also magnesium phosphates, sodium phosphates and even ammonium phosphates are used in animal nutrition. The end-product quality depends on the treatment and production process.

  5. Eutrophication - Wikipedia

    en.wikipedia.org/wiki/Eutrophication

    Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of microorganisms that may deplete the oxygen of water. [ 1 ] [ 2 ] Eutrophication may occur naturally or as a result of human actions.

  6. Freshwater aquarium algae - Wikipedia

    en.wikipedia.org/wiki/Freshwater_aquarium_algae

    Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...

  7. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4. The term also refers to the trivalent functional group OP(O-) 3 in such esters.

  8. Phosphorus deficiency - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_deficiency

    Phosphorus deficiency is a plant disorder associated with insufficient supply of phosphorus. Phosphorus refers here to salts of phosphates ( PO 3− 4 ), monohydrogen phosphate ( HPO 2− 4 ), and dihydrogen phosphate ( H 2 PO − 4 ).

  9. Phosphorus cycle - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_cycle

    The phosphorus cycle is the biogeochemical cycle that involves the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based materials do not enter the gaseous phase readily, [1] as the main source of gaseous phosphorus ...
