Commercial fisheries often catch species that are not targeted by the fishing operation (bycatch). Since this bycatch is not fully recorded it is necessary to estimate the absolute quantity using observer data. In this study we compare estimates from a ratio-based approach with a model-based estimator using data from the ling longline fishery, and scampi and squid trawl fisheries. It is argued that a model-based estimator should be the preferred approach for future work of this kind.
