Data underlying the publication: Co-cultivating sugar kelp and blue mussel in a mesocosm experiment

Low trophic aquaculture (LTA) is receiving increasing interest, this includes the cultivation of seaweed and shellfish. This study explores any potential benefits or disadvantages of co-cultivating two LTA species, sugar kelp (<em>Saccharina latissima</em>) and the blue mussel (<em>Mytilus edulis</em>), in a mesocosm experiment. The experimental setup comprised 4 treatments divided over 24 tanks: either seaweed or mussels, both in co-cultivation, and a control with neither. The aim was to assess the growth and performance of <em>S. latissima</em> and <em>M. edulis</em> in the different treatments during the production cycle of seaweed (November to April).
