• -Systematic echointegration (done at 8 knots on legs from shore to offshore, perpendicular to the coast and 12 NM apart) using ER60,70, 120 and 200 KHz echosounders and archiving by MOVIES+.
  -Trawl hauls to identify echoes (44 performed, 2 of which using the 4FF).
  -Biometry of pelagic species.
  -Bathymetric (T, S) profiles taken at the end of each trawl haul (45 CTD)and at the end of each leg.
  -Continuous T (Temperature) and S (Salinity) recorded at subsurface (1704 MN).
  -Continuous recording of echograms sent by 38, 70, 120 and 200 kHz echosounders (1,704 nautical miles).
  -Otolith samples taken from anchovy and sardine (400 + 250).
  -Otolith samples collected and biometry measured for 70 hake.
  -Biometry on anchovies (2,426) and sardines (2,332).
