  2. Berlin Method - Wikipedia

    en.wikipedia.org/wiki/Berlin_Method

    The Berlin Method of biological filtration is a method for maintaining a clean and stable environment within a saltwater aquarium, typically a coral reef system. This method relies on the use of ample live rock (rock with live marine organisms and bacteria on or in it).

  3. Raceway (aquaculture) - Wikipedia

    en.wikipedia.org/wiki/Raceway_(aquaculture)

    A raceway, also known as a flow-through system, is an artificial channel used in aquaculture to culture aquatic organisms. Raceway systems are among the earliest methods used for inland aquaculture. A raceway usually consists of rectangular basins or canals constructed of concrete and equipped with an inlet and outlet.

  4. Coral reef restoration - Wikipedia

    en.wikipedia.org/wiki/Coral_reef_restoration

    These pieces are then affixed to a ceramic or cement base called a plug and placed in land nursery tanks. [21] Massive reef-building coral are the prime species used in this method, because it speeds up their growth rate. Rather than waiting decades for a coral to grow to a robust size, months are needed to see viable specimen. [24]

  5. Oyster reef restoration - Wikipedia

    en.wikipedia.org/wiki/Oyster_reef_restoration

    Oyster Reef. Oyster reef restoration refers to the reparation and reconstruction of degraded oyster reefs.Environmental changes, modern fishing practices, [1] over harvesting, [2] water pollution, and other factors, have resulted in damage, disease, and ultimately, a large decline in global population and prevalence of oyster habitats.

  6. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    For hydroponic uses, total dissolved solids are considered one of the best indices of nutrient availability for the aquatic plants being grown. Because the threshold of acceptable aesthetic criteria for human drinking water is 500 mg/L, there is no general concern for odor , taste, and color at a level much lower than is required for harm.

  7. Cleaning station - Wikipedia

    en.wikipedia.org/wiki/Cleaning_station

    Cleaning stations are an exhibition of mutualism. Cleaner fish also, obviously, affect cultural diversity around coral reefs, since clients with larger home ranges can access and, thus, choose between, a variety of cleaning stations, [3] visitor clients sometimes traveling long distances to a particular cleaning station. [4]

  8. Aquatic ecosystem - Wikipedia

    en.wikipedia.org/wiki/Aquatic_ecosystem

    These systems contrast with freshwater ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply [3] [4] and 90% of habitable space on Earth. [5] Seawater has an average salinity of 35 parts per thousand of water.

  9. Brackish-water aquarium - Wikipedia

    en.wikipedia.org/wiki/Brackish-water_aquarium

    Generally, aquarists need to maintain a specific gravity of around 1.005 to 1.010 depending on the species being kept, but practically all brackish water fish tolerate variations in salinity well, and some aquarists maintain that regularly fluctuating the salinity in the aquarium actually keeps the fish healthy and free of parasites.
