Sec. 230.51  Recreational and commercial fisheries.

    (a) Recreational and commercial fisheries consist of harvestable 
fish, crustaceans, shellfish, and other aquatic organisms used by man.
    (b) Possible loss of values: The discharge of dredged or fill 
materials can affect the suitability of recreational and commercial 
fishing grounds as habitat for populations of consumable aquatic 
organisms. Discharges can result in the chemical contamination of 
recreational or commercial fisheries. They may also interfere with the 
reproductive success of recreational and commercially important aquatic 
species through disruption of migration and spawning areas. The 
introduction of pollutants at critical times in their life cycle may 
directly reduce populations of commercially important aquatic organisms 
or indirectly reduce them by reducing organisms upon which they depend 
for food. Any of these impacts can be of short duration or prolonged, 
depending upon the physical and chemical impacts of the discharge and 
the biological availability of contaminants to aquatic organisms.
