With all this as background it seems logical now to put a price tag on pollution of coastal estuarine waters to assess economic effects especially from the perspective of fish and shellfish resources and human well-being. That kind of assessment can be performed with some degree of adequacy for short-term immediate impacts such as those associated with oil spills but longer-term effects such as possible reductions in available living resources or rejection of seafood products because of fear of contamination are more difficult to quantify. An attempt at economic evaluation is almost obligatory though because to many people translation of biological or environmental findings into dollars and cents terms is a necessary prelude to any conclusions that might be reached about pollution effects and to some of those same people unless an economic effect can be clearly demonstrated the issue is unimportant. The topic of economic impacts of coastal pollution can be introduced with two back-to-back vignettes about historical aspects of the problem. The first and most recent is called Plight of the Hudson River Fisherman and the second The Great Contaminated Fish Scare in Japan. Plight of the Hudson River Fisherman The lower reaches of the Hudson River just above the compressed insanity that is New York City but still within the range of the tides have for entire lifetimes been favorite hunting grounds for George Kundera and his friends all members of a special breed of small-boat commercial fishermen. His town is near the shores of that much-abused waterway and his prey varies with the changing seasons shad eels striped bass menhaden clams and assorted other species. He catches whatever is available and marketable at the .
