1.1 DEFINITION. Aquaculture is the farming of aquatic organisms, including fish, molluscs, crustaceans and plants. It implies some form of intervention in the rearing process to increase production, such as regular stocking, feeding and protection against predators.
1 Shellfish aquaculture is a sustainable and green industry. 2  Shellfish harvest helps to improve sediment quality by loosening and dispersing silt and muck, and helps add oxygen to bottom waters and sediments. 3  Oysters can filter 100 gallons of seawater in a single day as part of their natural feeding process. Shellfish feed on phytoplankton, but can also accumulate marine biotoxins, chemical contaminants, and pathogenic microorganisms, such as bacteria and viruses, effectively removing them from the water column.
