Commercial cultivation and bioremediation potential of sugar kelp, Saccharina latissima, in Danish waters

Several seaweed species have been successfully tested for their biofilter potential for integrated multi-trophic aquaculture (IMTA). In this study, Saccharina latissima bioremediation potential was assessed over 12 months with respect to the yield, phosphorous (P) and nitrogen (N) content and remova...

Zusammenfassung:	Several seaweed species have been successfully tested for their biofilter potential for integrated multi-trophic aquaculture (IMTA). In this study, Saccharina latissima bioremediation potential was assessed over 12 months with respect to the yield, phosphorous (P) and nitrogen (N) content and removal. The experiment took place at two commercial cultivation areas: in close proximity to a blue mussel and fish farm (IMTA) and at a reference site, both situated outside Horsens Fjord in Denmark. The maximum biomass yield over the first growing season was achieved in August (1.08 ± 0.09 and 1.51 ± 0.13 kg fresh weight (FW) m −1 ) and September (0.92 ± 0.18 and 1.49 ± 0.16 kg FW m −1 ). Yield was significantly higher at the IMTA compared to the reference site in August ( P
