NEGATIVE EFFECTS: high tides
As most fishermen know, the strongest tides usually (there are no absolutes in nature) occur at the time of full or new moon (This is because the tides are the highest or lowest - for the month - during these times. Our average tide in Ogunquit is 9 to 9.5 feet (9 feet is considered normal). Anything above this is higher than normal. The higher the tide, the stronger the current - generally speaking.). The stronger the tide, the faster the drift and the harder it is to fish. Also, strong tides generally have a negative effect on groundfish feeding patterns. Many feel that the extra available light during the night of a full moon has a negative effect on fishing during the day.
The tides deposit water (and its nutrients) over greater areas of land, while cleansing coastal areas.
Salt marshes are formed and sustained by tidal activity and play an important part in the overall health of Long Island Sound. Tides deposit sediment across low-lying coastal areas and form mudflats. Grasses and plant matter decay, while sediment builds, and hundreds of diverse organisms find home in the nutrient rich layers. These layers become breeding grounds for fish and shellfish.
Some salt marshes are among the most productive habitats on earth in terms of the quantity of vegetation produced each year. Costly cultivation and fertilization are needed to achieve comparable agricultural yields in upland areas, services that the tides freely provide to salt marshes.
