Recirculating aquaculture system. 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 ...
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. [ 1 ][ 2 ] Plants are grown in hydroponics systems, with their roots ...
Seaweed fertiliser (or fertilizer) is organic fertilizer made from seaweed that is used in agriculture to increase soil fertility and plant growth. The use of seaweed fertilizer dates back to antiquity and has a broad array of benefits for soils. Seaweed fertilizer can be applied in a number of different forms, including refined liquid extracts ...
v. t. e. 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 water of oxygen. [1][2] Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, industrial ...
[15] [16] Hundreds of kilos of fish and oysters cultured here were sold. Researchers also quantified the water quality parameters and nutrient budgets in (5 kg fish m −3) green water seabream ponds. [15] [17] The phytoplankton generally maintained reasonable water quality and converted on average over half the waste nitrogen into algal biomass.

t. e. Dissolved organic carbon (DOC) is the fraction of organic carbon operationally defined as that which can pass through a filter with a pore size typically between 0.22 and 0.7 micrometers. [2] The fraction remaining on the filter is called particulate organic carbon (POC). [3] Dissolved organic matter (DOM) is a closely related term often ...
