Abstract
The majority of trawl selectivity studies for the three redfish species of particular commercial importance
in North Atlantic fisheries: Sebastes marinus, Sebastes mentella and Sebastes fasciatus, are based on
data collected from diamond mesh codends with mesh sizes ranging from 88 mm to 147 mm. We
demonstrate how results from these studies can be understood by morphological characteristics of
the species. We predict codend size selection based on morphological data collected from golden
redfish (S. marinus) individuals. Further, consistent with previously reported morphological similarities
between the three redfish species, we show the predictions for S. marinus may successfully be
extrapolated to understand experimental codend size selectivity results reported for S. mentella and
S. fasciatus. In addition to the comparison with previously reported data, we present new experimental
results for a codend applied in Northeast Atlantic redfish trawl fishery.
