| Abstract: | The influence of shrimps on turbidity was examined in laboratory and field experiments. Palaemonetes varians in the laboratory stimulated populations of both rotifers and Anabaena, which was the main cause of increased turbidity. In field experiments, P. varians increased and Neomysis integer decreased turbidity. In feeding trials P. varians took cladocerans and culicids in preference to copepods. It is considered that shrimps are likely to be important predators of cladocerans in shallow, coastal waterbodies and result in phytoplankton blooms, with reduced water transparency.
