In fish culture, traditional
raceways are enclosed channel systems with relatively high rates of moving or
flowing water. This high rate of water movement gives raceway systems distinct advantages
over the other culture systems.

of fish waste is easier
Most raceway operators believe they
have more control over their fish production, and they see this as the major
benefit of raceway culture. This control is achieved only if flow rate and
water quality are relatively stable over time. Stocking densities for raceways are
usually higher than for other culture systems.
