“…Stomachs were fixed in 96% alcohol or in 10% formaldehyde. Samples were characterised according to year, season, latitude, zone (north 3°-6°S, centre-north 6°S-10°S, centre-south 10°-15°S, south 15°-18°S), distance to the shelf break (in km, negative to the continental shelf and positive towards offshore), sea surface temperature anomalies (SSTA, in°C) and depth of isotherm 15°C (Z 15°C , in m; see Flores et al, 2013). In addition, fish length and distance to the shelf break were classified in ordered categories: less than 20 cm, then by 10 cm bins above, for length; À100 to À10 km (i.e.…”
