ABSTRACT
Zooplankton are tiny, swimming, animals, that are represented mostly by crustaceans, rotifers, and protozoans. They include both primary consumers that feed on phytoplankton and secondary consumers that feed on other zooplankton. They are a major component of the diet of fishes, especially small fish and the larvae of larger fish, and are therefore essential to the productivity of the Mekong fishery.
Relative to diatoms and macroinvertebrates, zooplankton have not been widely used in biological monitoring studies. According to the scientific literature, they do offer specific advantages for biomonitoring in that they are a diverse group with a variety of species having a range of responses to environmental changes. Like diatoms, they have a short generation time and thus a rapid response to environmental changes and recovery from disturbance. There are reported disadvantages associated with the use of zooplankton in biological monitoring programs as well. There are sampling issues associated with their daily fluctuations in abundance and composition, and patchy spatial distributions related to current and depth. As with diatoms, there are few metrics or indices that have been proved to be consistently effective in biomonitoring programs.
Most research on zooplankton in the region has been on taxonomy and species distributions, and importance as fish food. An taxonomic key (which is currently unavailable) to assist the identification of zooplankton species, would help facilitate the use of these animals for biomonitoring on a regional scale.
This chapter describes the zooplankton assemblages recorded from 77 sampling events at 51 sites in 2004 - 07 and their relationships with environmental variables.
