![]() ![]() rhizophorae, the spat collectors mainly used are metallic root made of aluminum wire (Riaño and De La Osa, 2003) and in Venezuelan cultures they are still using Spanish tiles as spat collectors (Narciso, 1995). In the Colombian commercial cultures of C. Most collectors tested were inappropriate because they were expensive, labour intensive to construct (e.g., asbesto-cement), were not appropriate settlement substrates (e.g., mangrove roots and asbesto-cement), the materials were short-lived (e.g., wood), or because it was difficult to remove young oysters from the materials (e.g., oyster shells). Collectors made of mangrove roots, oysters shells, aluminium, PVC, asbestos-cement, wood, fibreglass, car tires and Spanish tiles have been used to collect the spat of the mangrove oyster C. In oyster aquaculture, a variety of materials have been used for spat collection. ![]() The collection of wild spat is critical to the success of culture of many commercial bivalves (Pillay, 1997). ![]() rhizophorae in the “Laguna de la Restinga” on Margarita Island to meet the demand for this species. We are presently examining techniques for the culture of C. Consequently, natural oyster banks are subjected to high exploitation. The species is preferred for its flavour and is commonly served in the shell to tourists on beaches. In Venezuela, there is a high local demand for the mangrove oyster, Crassostrea rhizophorae. ![]()
