Demarcation of collective aquaculture areas to <i>Crassostrea rhizophorae</i> (Guilding, 1828) farming in Pernambuco - Brazil

Abstract

This study aimed to delimit collective aquaculture areas to the “native oyster” Crassostrea rhizophorae farming, as part of the of Local Plan Mariculture Development in the north coast of Pernambuco. Indicators were identified, selected and hierarquized to enable the elaboration of a conceptual model
subsidizing the selection process of potential oyster farming areas. Depth measurements were realized in transversal sections of the estuarine channels using ecobathimeter linked to a GPS (Global Positioning System) and a Palmtop. In the of aquaculture area eight environmental, seven socioeconomic and five production/logistics indicators were identified to subsidize the selection process of the oyster farming potential areas. Three preferential areas were delimited, in which six collective aquaculture areas were demarcated, being three in the municipality of Goiana (estuary of the river Itapessoca), two in Igarassu (estuary of the river Timbó) and one in Itapissuma (Santa Cruz channel), where 263 individual aquaculture areas could be inserted, totalizing 77,2 ha of collective aquaculture areas.
