Many also release the water they catch slowly into the ground. As they do this, they recharge ground water supplies and extend stream flows that are critical in some parts of the United States. Commercial Fisheries Wetlands, particularly those in coastal areas and along streams, are an integral part of the cycle of many fish. Northern pike, perch and pan fish rely on wetlands for their survival. In fact, coastal wetlands are the nursery and spawning grounds for 60 to 90 percent of US commercial fish catches.
