Paracyclops fimbriatus can be easily cultured as a food source for juvenile fish. The crustacean can be fed protozoans living in sewage sludge and in hay infusions. When properly fed, the cyclopoid densities can be as high as 1000 000 inds/dm3. Methods of culture and harvest of the crustaceans are described. Data on length and biomass of all the 12 developmental stages are reported as well.
Polythene sheets deployed in Lake Miewie (area 3500 ha) were chiefly colonized by the zebra mussel, Dreissena polymorpha Pall. They were also used as substratum by freshwater triclads, oligochaetes, leeches, and snails for attaching eggs, and as spawning ground by fish. On the other hand, the development of algae on them was very poor. The sheets survived undamaged a year in the littoral zone of the lake characterized by very strong waves and horizontal currents.
