Species Diversity of Zooplankton in the Curonian Lagoon in 2001

Abstract

Species diversity, biomass and abundance of zooplankton were studied in the Curonian Lagoon in 2001. The studies revealed that changes in the abundance, biomass and species diversity of zooplankton depended on the sites and time of sampling. Forty-one species of zooplankton was identified from samples collected in the Curonian Lagoon. The zooplankton community was dominated by Chydorus sphaericus and Thermocyclops oithonoides. Shannon-Weaver biodiversity index depended not only on the sites and time of sampling, but also on a particular part of the Curonian Lagoon where the samples were collected.
