A zooplankton bioassay chamber for lab and field use

Field and laboratory study of zooplankton has been hampered by the lack of standardized and reliable culture methods. This paper describes a zooplankton bioassay chamber for both laboratory and in situ use that is easy to construct, inexpensive, and suitable for even very small zooplankton species such as Bosmina . The chamber, which allows easy access to animals for examination or counting, may be particularly useful in toxicity bioassays.
