Scottish Marine and Freshwater Science Volume 3 Number 6: Development of a GIS based Aquaculture Decision Support Tool (ADST) to determine the potential benthic impacts associated with the expansion of salmon farming in Scottish sea lochs
This paper presents a GIS based aquaculture decision
support tool (ADST) to assist with planning the sustainable development of the aquaculture
industry in Scotland.
Annex 4
Theoretical potential maximum biomass (B TMAX) values for Scottish sea lochs with the corresponding areas required to produce this biomass (A REQ) (Lochs ordered by region).
(BOLD values = limiting factors)
(Italic values = Values where B TMAX were based only on nutrient enrichment as there were not enough data to run ECE_MOD (11 sea lochs))
( *naa = no A (15-70 m) available (10 sea lochs).
