Stickleback fish (Gasterosteus aculeatus) and daphnids (Daphnia Magna) were placed in cages in the reservoirs and roadside ditches associated with cranberry bogs before the application of insecticides through the irrigation systems. Rainbow trout (Oncorhynchus mykiss) did not survive the low pH in preliminary experiments. The Daphnia tests were inconclusive because there was a high mortality at the control sites. At the open bog where azinphos-methyl was applied there was 100 per cent stickleback mortality in the 96 h after chemigation at both test sites, but none at the control site. At the closed bog where parathion was used the stickleback mortality was 7 and 3 per cent at 2 test sites and zero at the control site. Stickleback fish appeared to be suitable test organisms for bog environments.
