Resumo: | We present a series of exploratory stock assessments for roundnose grenadier (Coryphaenoides rupestris) from estimates of catch data based on information and assumption of discards and landing statistics. It is a common practice to consider landings data as a substitute of catch data to perform stock assessments. When a significant portion of the catch is discarded, this assumption is likely to be misleading as assessment methods will provide underestimated stock size.
