Objective	This cruise was part of the programme for quarterly assessments of the quantities of various species (hake, sole, Nephrops prawn, etc.) discarded by fishing vessels (individuals under the legal landing size). These assessments, along with data collected from the demographic structure of landings (using samples from fish auctions), are critical for the evolution of commercial fish stocks. Other occasional operations included collecting biological material, etc.
