- Information was taken from CCAMLR observer reports and interviews with fishing masters;
- The variation in reported conversion factors for similar reported products can be attributed to a number of reasons:.; o Differences in the method of processing the same products o Seasonal variation o Spatial variation o Krill water content o Reporting errors (recording percentage recovered instead of conversion factor)
- Uncertainty in reported Conversion Factors does not necessarily lead to uncertainty in total catch estimates as the majority of vessels interviewed made direct estimates of green weight catches; and,
- A need for closer monitoring of processing methods, calculation of green weight catches, and conversion factors where appropriate, this could be enhanced by greater observer coverage.
