Good read newfish

"The effects of poor DO levels in cages can be improved in three ways: 1) modifying the environmental DO levels through adding oxygen to the cages; 2) only feeding fish when DO levels are above LOS and in the range where they can effectively utilise the feed; and 3) minimising stocking densities to reduce cage-scale draw down of DO levels.
