Measurements 
Biology and fisheries 
Pelagic fishQuantity: number of hauls = 45
Description: For each haul the measurement of length for fish caught was taken associated with the otolith at length. Also skin samples were taken for DNA analysis, to establish possible stock discrimination. Stomach samples were also collected in order to study feeding ecology.
Demersal fishQuantity: number of hauls = 45
Description: For each haul the measurement of length for fish caught was taken associated with the otolith at length. Also skin samples were taken for DNA analysis, to establish possible stock discrimination. Stomach samples were also collected in order to study feeding ecology.
Exploratory fishingQuantity: number of hauls = 45
Description: For each haul the measurement of length for fish caught was taken associated with the otolith at length. Also skin samples were taken for DNA analysis, to establish possible stock discrimination. Stomach samples were also collected in order to study feeding ecology.
