Discards are de ned as the shery catches returned to the waters, dead or alive. The aim of this analysis consists on identifying the main socioeconomic, technical and biological variables explaining the discards produced by countries from 1962 to 2013. For this purpose, the analysis relies on General Additive Models (GAMs). The signi cance of the economic, technical and biological variables on the estimations of this analysis shows the complex nature of discards, intending to provide a broad idea on the additional aspects that should be kept in mind when designing e ective international policies to minimize discards.
