how the future might look with regard to artificial reefs in
fisheries can be seen in the example off South Korea
(Kim et al., 2011). In this study, artificial reefs were
deployed to enhance spawning success in a bottomdwelling fish species. The reef deployment, coupled with
fishing restrictions, is part of a long-term plan to increase
a depleted fish stock. Similar investigations may give
purposeful direction to future artificial reef designs and
deployments.
Summary
Objects of various materials, shapes, and dimensions have
been deployed in nearly every aquatic environment in all
parts of the world to serve as artificial reefs. Few artificial
reefs have been deployed in estuaries. Nevertheless, oyster shell material, deployed to improve oyster settlement
can be considered an artificial reef or at least an artificial
substrate that behaves similar to other objects deployed
as artificial reefs. Artificial reefs have received considerable attention among aquatic scientists and natural
resource managers to facilitate fisheries. However, there
remain several issues relative to the attraction versus production nature of artificial reefs that need to be resolved
before they become part of a regularly prescribed option
for estuarine resource management.

Definition
Autotrophic organisms use an inorganic carbon compound for their sole carbon source (Okafar, 2011). The
corresponding pathways of carbon metabolism are also
referred to as autotrophic.
Etymology: from Greek autόB, self, and Greek trοjή,
nourishment.
