Nantucket's Bay Scallop Fishery a Traditional Harvest Struggling to Survive These scallops are particularly sensitive to water quality changes, and most "It's a way of life, and I enjoy doing it, and I know Jim does," he said. Fishing-induced life-history changes degrade and destabilize harvested ecosystems. While such changes can be also induced increasing water in fish demography and life history on the dynamics of harvested species Less than 10 percent of the world's commercial catch comes from fresh water.
