✦ Synopsis

Critical aspects of growing Laminaria saccharina and Nereocystis luetkeana near salmon sea cages are discussed . A new computer spreadsheet model was developed, which integrated biological, physical and economic aspects of kelp/salmon cultivation, in order to provide information on production, nutrient removal, and technical and economic feasibility of different production strategies . Given a farm-gate price of $20 kg -' (dry mass) and either a 24 or 48 sea cage salmon farm, kelp is a feasible investment option . Results of the model suggest that kelp apparently obtains ammonium for growth during slack tide and that ammonium uptake is also significant during that time . The net yield of Nereocystis needs to be increased before it can compete with the yield of Laminaria .

• include kelp on a salmon farm, a part-time position and a separate mooring system for kelp would be needed . Special attention should be given to training personnel in both salmon and kelp production .
