The results obtained from 62 stations sampled in the Gulf of Cadiz, Straits of Gibraltar and Alborán Sea (north-west sector) during July 1994 are analysed. The zooplankton sampling was conducted virtually simultaneously with study of temperature, salinity and nutrients. The main hydrological characteristics registered during the survey and their relationship with zooplankton composition and distribution are presented. The different geographical locations and the particular topography and oceanography of the Gulf of Cadiz and the Alborán Sea have clearly affected the spatial distribution and the taxonomic composition of the ichthyoplankton and the holoplankton found on both sides of the Straits of Gibraltar.Postprint
