The Caucahué Channel. Sampling sites (circles), sampling track (black arrows) and approximate time of zooplankton sampling on June 19. Q sites are near aquaculture centers (green = mytilids, red = salmonids) and C sites are far from aquaculture centers. The zooplankton sampling track begins at site C10 (08:30 h) and ends at site C6 (20:30 h). Blue triangles indicate CTDO sampling sites on June 30. The blue star indicates the ADCP monitoring site
