INTERANNUAL VARIABILITY OF ZOOPLANKTON IN THE RÍA DE VIGO, NORTHEAST ATLANTIC.
From 1997 to 2005, a mesozooplankton monthly study was carried out in a station located in the Ría de Vigo (42º 13, 3´ N, 8º 47, 7´ W) at a depth of 29 m. Its biomass was estimated and a range of 0.23-208.47 mg dry weight free of ash per m3 was found. Total abundance was counted and interannual rang...
