Description: In result of investigated material collected by the author during the Soviet-Cuban expedition in 1964—1965 were determined the main features of zooplankton distribution in the Gulf of Mexico and the West Caribbean Sea. Quantitative indices of zooplankton in investigated regions do not differ at their base from those of the Tropical part of the Atlantic Ocean. The most productive areas distinguished are those where the increase in zooplankton quantity is due to upwelling and connected with this, an increase in quantity of biogen elements. The maximum zooplankton quantity in this region is timed to water masses having a temperatura of 26.2°—27.5° during the autumn-winter period, and a salinity within the limits of 36.2—36.8%. The qualitative composition of zooplankton is characterized by a large species variety. In the investigated region were registered 200 copepod species and 13 chaetognath species. The complex zooplankton are of a mixed character. In similar tests alongside with oceanic epiplankton species can be found neritic and deep water species. This is connected with the character of current as well as diurnal migrations and meteorological conditions. The characteristic features of zooplankton distribution, the author connects with the distribution of currents in investigated region.
