  2. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    Ammonia is toxic to aquatic life which leads to increased amounts of fish deaths. [6] Ammonia pollution also leads to eutrophication. Eutrophication is the growth of algae that kills other aquatic life and creates dead zones. Ammonia pollution affects freshwater and salt water ecosystems differently due to physical and chemical differences.

  3. Freshwater environmental quality parameters - Wikipedia

    en.wikipedia.org/wiki/Freshwater_environmental...

    Ammonium ions also have a toxic effect, especially on fish. The toxicity of ammonia is dependent on both pH and temperature and an added complexity is the buffering effect of the blood/water interface across the gill membrane which masks any additional toxicity over about pH 8.0. The management of river chemistry to avoid ecological damage is ...

    A purple sea urchin being tested for pollution using a whole effluent toxicity method.. Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.

  6. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]

  7. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Ammonia occurs in nature and has been detected in the interstellar medium. In many countries, it is classified as an extremely hazardous substance. [15] Ammonia is produced biologically in a process called nitrogen fixation, but even more is generated industrially by the Haber process. The process helped revolutionize agriculture by providing ...

  8. Ammonia poisoning - Wikipedia

    en.wikipedia.org/wiki/Ammonia_poisoning

    An ammonia test is the most sure way of diagnosing ammonia poisoning. Ammonia affects fish metabolism and their ability to absorb oxygen through their gills. This leads to a host of symptoms a few of which are: Purple, red or bleeding gills; Fish may clamp, may appear darker in color; Red streaking on the fins or body

  9. Environmental impact of fishing - Wikipedia

    Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
