Abstract

1. to review the technical literature concerned with methodologies used to measure the toxic threat to salmonid fish and sensitive freshwater invertebrate species, due to the application of forestry herbicides. 2. to develop a meaningful, cost-effective bioassay protocol for evaluating the relative degree of risk to regional fisheries resources, posed by these chemicals.

This report reviews the bioassay test procedures used to date for evaluating the toxicity of herbicides to salmonid fish and sensitive freshwater invertebrate species. Based on this review, and in consideration of regional needs as well as the most promising and applicable test procedures and approaches, a tentative bioassay protocol is developed and presented.
