Vertical migration of marine copepods in the Galapagos Islands in relation to size and color

Abstract

This study examined the relationships between the vertical migration pattern of copepods and their body conditions in term of body size and body coloration. Zooplankton samples were collected by net sampling at locations in the western regions of the Galapagos Islands on 14-15 January 2006. Copepod abundance, body length, and color were examined. Observations show that individual body conditions of copepods are directly related to their vertical migration.
