  • oxygenation

    Process of providing, combining, or treating with oxygen.

    Used in 273 profiles

  • dissolved oxygen

    The concentration of oxygen dissolved in a water body. Normally expressed in milligrams per liter, parts per million, or percentage saturation.

    Used in 296 profiles

  • aerobic

    Living or occurring only in the presence of oxygen.

  • anaerobic

    Living or occurring in the absence of oxygen.

  • eutrophication

    Hypertrophication; process by which addition of artificial or natural substances, such as nitrates and phosphates, to a body of water increases the concentration of dissolved nutrients, this in turn stimulating the growth of aquatic plant life, especially phytoplankton, and typically resulting in depletion of dissolved oxygen. Negative effects include reductions in populations of fishes and other organisms incapable of withstanding this hypoxia.

  • gill filament

  • hypoxia

    Oxygen deficiency in blood or tissue.

  • labyrinth organ

    Highly folded, vascularised, suprabranchial accessory breathing organ formed via extension of the first epibranchial bone and used to respire atmospheric oxygen. Found in all members of the freshwater fish suborder Anabantoidei.

  • oxidation

    Chemical process whereby an atom or ion loses electrons and undergoes a subsequent increase in valence; the combination of a substance with oxygen; the act or result of being oxidised. Opposite of reduction.

  • redox

    Abbreviation of reduction-oxygenation. Used in reference to a chemical process whereby one substance or molecule undergoes reduction and another oxidation.

  • respiration

    The process by which an organism acquires the oxygen necessary for metabolism and expels excess carbon dioxide formed during energy-yielding reactions.

  • silicate

    Any of a largegroup of chemical compounds containing silicon, oxygen, and at least one metal. Most rocks and minerals are silicates.
