Fed aquaculture (for example, fish, shrimp) is combined with inorganic extractive and organic extractive (for example, shellfish) aquaculture to create balanced systems for environmental sustainability (biomitigation), economic stability (product diversification and risk reduction) and social acceptability (better management practices).

Raceways at a West Virginia fish hatchery Flow-through raceway system in Masis, Armenia. 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.
Broodstock management involves manipulating environmental factors surrounding the broodstock to ensure maximum survival, enhance gonadal development and increase fecundity. [3] Such conditioning is necessary to ensure the sustainability of aquaculture production, [ 4 ] and to increase the number and quality of eggs produced and control the ...
