Abundance and composition of zooplankton in the straits of Malacca

The zooplankton composition and distribution were studied during four oceanographic cruises in the Straits of Malacca between November 1998 and August 2000 with 140 μm-mesh and 45-cm diameter NORPAC net. Zooplankton samples were analyzed for the faunal composition and abundance. Zooplankton abundanc...
