Work Package 4 on spatial planning in Aquabest aims to develop a spatial planning manual, which is used in two Swedish cases in order to evaluate the usefulness of the manual.
One identified important action in the spatial planning manual
is the performance of a GIS-analysis in order to identify suitable
localities for aquaculture farms.
This report presents a GIS-model developed for localizing
open-cage farms in freshwater lakes. As a first step, the model
identifies and ranks the lakes which are most suitable for
aquaculture. In addition the model includes a biological diversity
parameter, for which three classes are identified; 1) fish farms
probably OK with respect to biological diversity, 2) fish farms
probably not OK until national guidelines are developed for risk
assessment with respect to fish farms in relation to natural
populations, and 3) fish farms not suitable in these lake due to
the presence of natural populations worthy of protection. After the
lakes are identified and ranked, the model divides the lakes in
500*500 meter squares in order to do analysis for suitable
localities within each lake.
The aim of the report is to identify the most suitable lakes for
fish farms and identify possible administrative and physical
obstacles for establishing fish farms at certain localities in
specific lakes. Authors wish is that the report will serve as
a basis for further discussions and investigations for authorities,
municipalities and companies interested in starting fish farms in
the Jämtland county. Finally we hope to demonstrate how principles
of spatial planning can be utilized in promoting sustainable new
economic activity in the Baltic Sea region.
