The short-term effects of three molluscicides on the microflora and microfauna of small, biologically stable ponds in Southern Rhodesia.

摘要: Abstract Where large-scale molluscicide applications are anticipated, it is important to investigate the effects of chemicals be used on freshwater microflora and fauna existing in bodies water treated. The food chains which these organisms form basic parts general ecology leading up fish even man. Some observations direct short-term effect three molluscicides—copper sulfate, sodium pentachlorophenate Bayer 73—on populations certain plankton organisms, carried out biologically stable ponds Southern Rhodesia, reported this paper. It appears that copper sulfate has most drastic long-lasting organisms. authors stress snail control measures involving molluscicides should so designed as minimum alteration ecological balance habitat.
