Krill conversion factors

Published information on conversion factors to estimate krill removals from the amounts of different krill products are examined and a range of values produced. These are broadly in line with those currently in use although the differences are such that use of the traditional factors may introduce large errors into the estimation of removals. It is uncertain whether discarding is a common practice in the fishery, if it is then the use of any of the conversion factors will result in a serious under-estimation of total removals.
