FP7-IDREEM project Milestone 18. Part I: Review of the production parameters at the Oldervika salmon farm (Nordland, Norway)

Abstract

The report is a study of the salmon farm at Oldervika in Morsdalsfjorden in Gildeskål Township (Nordland, Norway). The study focuses on the environmental and ecological parameters registered at the site since 2007 by Gildeskål Research Station AS (GIFAS). The salmon farm has a total maximum allowed biomass of 1560 tons and it is now in its third production cycle. The farm is located over a flat basin of 140 m depth, and is exposed with moderate tidal currents (NV-SE as dominating current directions). Temperature and salinity has been recorded discontinuously during the years of activity, and the mandatory sediment analyses indicate that the farm site is moderately affected by the activity. This site has therefore been chosen as demonstration site for an interdisciplinary research project (Increasing Industrial Resource Efficiency in European Mariculture – FP7 - IDREEM). This project will address the obstacles and challenges of IMTA, and on this basis develop economic, environmental, technical, social or legal solutions. IDREEM will provide tools and evidence based on knowledge to support adaptation to IMTA in the aquaculture industry.
