fish and explosives

Just came across an interesting question.  Does anyone know of research on the effects of land-based explosives on fish in nearby streams?  The project proponent is proposing the use of explosives to construct a road near a fish-bearing stream and there is a question about how to analyze impacts.  Not seeing much in the literature--just the use of explosives underwater, like for oil drilling.

Both the Alaska and Canadian Guidance discuss predicted overpressure from charges placed in substrate adjacent to waters, and how the pressure reacts in bedrock.

Not aware of studies that deal with the effects of explosives used on land--only studies that deal with the use of explosives underwater. Check out NCHRP Research Results Digest 363

There were some papers presented at the 2011 International Conference on Ecology and Transportation on noise impacts for fish (and other wildlife).  The proceedings are not yet released, but you could contact the authors directly.

For ESA consultation, we have reviewed blasting Guidline as they may involve Endangered Species and stream habitats (and bridge removal). We have not done an analysis or made any measurements but have reccomended these if a contractor wants to persue a blasting option.  As a start, we find that the State of Alaska, DF&G,  and the Canadian Dept of Fisheries and Oceans have guidelines
