Abstract
This study focused on the optimisation of offshore marine fish-cage farming in Tenerife, Canary Islands. The main objective was to select the most suitable sites for offshore cage culture. This is a key factor in any aquaculture operation, affecting both success and sustainability. Moreover, it can solve conflicts between different coastal activities, making a rational use of the coastal space. Site selection was achieved by using Geographical Information Systems (GIS) based models and related technology, such as satellite images and Global Positioning System (GPS), to support the decision-making process. The integration, manipulations, analysis and presentation of the results by means of GIS-based models proved to be very effective for helping the decision-making process of site selection in study. On the whole, this study revealed the usefulness of GIS as an aquaculture planning and management tool. Three different cage systems were selected and proposed for different areas around Tenerife. Cage systems that can withstand harsh environments were found to be suitable for use over a broader area of Tenerife's coastline. Thus, the more robust self-tensioned cage (SeaStation©) could be used over a greater area than the weaker gravity cages (Corelsa©). From the 228 km2 of available area for siting cages in the coastal regions with depth of 50 m, the suitable area for siting SeaStation? cages was 61 km2, while the suitable area for OceanSpar? and Corelsa? cages was 49 and 37 km2 respectively.
