  2. Organic aquaculture - Wikipedia

    en.wikipedia.org/wiki/Organic_aquaculture

    A number of countries have created their own national standards and certifying bodies for organic aquaculture. While there is not simply one international organic aquaculture standardization process, one of the largest certification organizations is the Global Trust, [9] which delivers assessments and certifications to match the highest quality organic aquaculture standards.

  3. Offshore aquaculture - Wikipedia

    en.wikipedia.org/wiki/Offshore_aquaculture

    Spreading of pathogens between fish stocks is a major issue in disease control. [27] Static offshore cages may help minimize direct spreading, as there may be greater distances between aquaculture production areas. However, development of roaming cage technology could bring about new issues with disease transfer and spread.

    "Biofuel production shall follow international treaties and national laws regarding such things as air quality, water resources, agricultural practices, labor conditions, and more. Biofuels projects shall be designed and operated in participatory processes that involve all relevant stakeholders in planning and monitoring.

  5. Commercial fish feed - Wikipedia

    en.wikipedia.org/wiki/Commercial_fish_feed

    In the current technology, fish feed extruders play a key role in production lines. Although the majority of the process of the fish feed production occurs in the extruder, grinding and mixing can highly affect the quality of the final product. [14] Water is added and the resulting paste is extruded through holes in a metal plate. The diameter ...

  6. Biofloc Technology - Wikipedia

    en.wikipedia.org/wiki/Biofloc_Technology

    Biofloc technology (BFT) is a system of aquaculture that uses "microbial biotechnology to increase the efficacy and utilization of fish feeds, where toxic materials such as nitrogen components are treated and converted to a useful product, like a protein for using as supplementary feeds to the fish and crustaceans."

  7. Ethanol fuel energy balance - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fuel_energy_balance

    Clean production bioethanol [20] is a biofuel obtained by maximizing non-greenhouse gas emitting (renewable) resources: energy directly consumed to make the ethanol is renewable energy . The farm equipment and ethanol plant use an ethanol engine , biodiesel , air engine or electricity cogenerated during ethanol production, or even wind power ...

  8. Aquaculture of sea sponges - Wikipedia

    en.wikipedia.org/wiki/Aquaculture_of_sea_sponges

    Sea sponge aquaculture is the process of farming sea sponges under controlled conditions. It has been conducted in the world's oceans for centuries using a number of aquaculture techniques. There are many factors such as light, salinity , pH , dissolved oxygen and the accumulation of waste products that influence the growth rate of sponges.

  9. Urban aquaculture - Wikipedia

    en.wikipedia.org/wiki/Urban_aquaculture

    Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
