| | | Review of the literature is an essential starting point for any endeavour in GIS, remote sensing, or mapping. Yet, reviews are often incomplete for lack of access to the material, and consequently projects experience durations that are longer and costs that are higher than need be because the accumulated knowledge has not been tapped and taken advantage of. This page sets out to mitigate that problem. It is a gateway to the literature that represents much of the accumulated global experience on using GIS, remote sensing and mapping to solve problems and issues in aquaculture and inland fisheries. Spatial issues addressed most frequently for aquaculture and inland fisheries are listed in two tables in issues section along with the number of literature records currently contained in GISFish databases. Four recent studies available for download in issues section provide background information on GISFish databases. | | | |

| | | Title | The potential for open ocean aquaculture in Exclusive Economic Zones from global and national perspectives | | Author | James McDaid Kapetsky and Jose Aguilar-Manjarrez | | Date | 12 December 2008 | | Content Language(s) | English | | Abstract / Description | Open ocean aquaculture (OOA) is perceived to have great promise, but its potential remains largely unknown. At present the promise is scarcely realized mainly due to technological limits on culture structures that can withstand the conditions of the open ocean and for lack of enabling environments. Prerequisites for development are estimates of potential in terms of species, culture structures, and locations suitable for development. Accordingly, the objective was to create an approach to enable developing countries to explore their own OOA.
This presentation builds on a reconnaissance study of OOA potential in the eastern Exclusive Economic Zones of the USA using Manifold GIS (Kapetsky and Aguilar-Manjarrez, 2007; http://www.fao.org/fishery/gisfish/id/2779). Following on the previous reconnaissance is an expanded study using Atlantic salmon (Salmo salar) and Cobia (Rachycentron canadum) as examples of fed aquaculture of cool and warm water species, respectively. The blue mussel (Mytilus edulis) exemplified cool water extractive aquaculture. Access in terms of port numbers and sizes and travel time to areas with potential for good growth of these species is analyzed as a limitation on OOA potential in the USA eastern EEZs. Because trophic diversification in offshore aquaculture is seen as an advantage from environmental and economic perspectives, estimates for the potential for OOA of Atlantic salmon with blue mussel for integrated multi-trophic aquaculture (IMTA) were conducted.
Shifting to a global perspective, estimates of OOA potential were made in the EEZs of countries with conditions corresponding to those required by the same three species. The OOA potential of each country was compared with its actual mariculture production and economic and social indices to identify its present OOA status or readiness to engage in OOA. In support of the Ecosystem Approach to Aquaculture, the marine ecosystems with high OOA potential were identified. Because OOA is so little developed, verification based on the locations of existing culture facilities is difficult. However, inferences were made from a few locations of adjacent inshore aquaculture of the same species. Refinements to this study are described, particularly to account for competing and conflicting uses of ocean space in relation to OOA potential.
