Example text

Probably the most important feature of the system, as in coastal marshes, is the export of large amounts of detritus by tidal currents to adjacent coastal waters, which form a major source of nutrients for maintaining productivity. For example, a stand of Rhizophora apiculata in southern Thailand was estimated to produce 7 t of leaves and 20 t ha−1 of wood per year. Some of this enters the foodweb as detritus. Phytoplankton production in coastal waters here is around 5000 mg C (carbon) m−2d−1. Heald (1971) estimated that 40% of the detritus in a south Florida estuary was exported from a mangrove swamp.

Besides the destruction of scenic landscapes, aesthetic objections to fish farm development were given as the use of vividly coloured buoys, unsightly buildings and outdoor working areas associated with farms, and the occupation of remote and unspoilt areas. A special commission was therefore appointed to study the environmental effects of the industry and to develop siting and operational guidelines for its management. Recognizing the need for the support of both the industry and the general public for any management policy to be effective, a new consultation policy has been adopted, to take into account the views of all interested parties before an application for establishment of a farm is approved.

This would involve not only major changes in the present farming systems, but the production and use of additional inputs and farming skills. More important for the environment is the increased loads of wastes in the discharges from the farms. This can, however, be controlled by appropriate waste treatment in the farms before discharge. 4 Selection of Water Bodies and Stocks to be Enhanced Though the underlying principle of all types of stock enhancement is the maximization of levels of production, the categorization of types of enhancement or the development of culture-based fisheries is complicated by the variety of circumstances under which it is employed in fisheries.
