As commercial finfishing is prohibited within Buzzards Bay waters, the marine economy most impacted by poor water quality conditions is the shellfishing industry. Unfortunately, only limited long- term information is available on local catches, and much of these data are of marginal quality for our purposes. The lack of information restricts our ability to look at long-term trends in economic losses caused by pollution or overfishing. Closures of shell- fish beds because of coliform contamination, how- ever, provide a general idea of the increased im- pact of anthropogenic activities within the water- shed (cf. Chapter 6). Although commercial marine activities do con- tribute some pollution to the bay, they also tend to be the most affected by pollution. This is particu- larly evident in the steady increase of shellfish bed closures caused by fecal coliform contamination, originating from road runoff, damaged septic sys- tems, and wildfowl and other animal wastes. The average of 1,764 ha closed to shellfishing in 1970 has steadily increased, reaching an average of 4,452- 4,856 ha in 1988 and nearly 6,070 ha in 1990. Although only a moderate portion of the overall shellfishery (primarily through recreational harvest), soft-shelled clams are particularly affected by bed closures since they are concentrated in areas most susceptible to bacterial contamination such as Fisheries Although early
