Water dark and fish deep in the water, when fish observed these looked to be in good condition. Feed response observed in several pens. Fish sampled for VMD appeared healthy. Cleaner fish observed near the water surface. A few pens with a few dead cleaner fish observed. A few were trapped in the fold of the nets that are used with swim throughs. Site manager says they try and organise doing these when the tide pushed the fish off the net. 14% Lumpfish stocked.
