Abstract

There is currently in the Nacional Parque Laguna de La Restinga an intensive exploitation of the natural banks of the mangrove oyster, Crassostrea rhizophorae by inhabitants of La Restinga town. Although this is one of the main sources of income for this community, the intensive extraction endangers this fragile marine ecosystem and threatens the definitive loss of the valuable mangrove oyster bank. Based on the existing problem, restocking of this species is necessary in the Laguna de La Restinga. For this purpose, a fixed structure was built to serve as nursery for collecting spat and to evaluate growth and body biomass increase of the oyster. This system will allow us to take biological information pertaining to the development and growth of Oyster, such as yield in animal protein and economic benefit of this type of aquaculture activity. In the other hand, the study of the possibility of development of this type of structure for oyster cultivation may become an alternative for its exploitation. This would allow the recuperation of natural banks through an extended closed season, without stopping the economic activity associated to the commercialization of the mollusk.
