Pearl essence, a silvery substance extracted from the scales of herring, and other schooling fishes is one of the many fish by products used. Pearl essence is important to the manufacturing of lipstick, nail polish, paints, ceramics and costume jewelry.
The Hudson River is the largest river entirely within state borders that is home to all members of the herring family. They spend the bulk of their lives in the ocean and only return to freshwater to reproduce.
Mixing and blending, rising and falling. The estuarine waters are constantly shifting between salty and fresh. The mixing often forms a layered gradient which determines what can live there.
The tidal ecosystems of the Hudson are vital to the health of the river.
The forest filters and neutralizes some pollutants such as acid rain and helps keep them out of the Hudson. The forest stabilizes land because roots tend to hold soil together. When the trees and large plants are cleared from river banks, erosion can result. Eroded soil and rock adds to the rivers’ load of sediments, impacting both plant and animal residents.
I heart NY. Why you ask? We live in a State where we are richly endowed with more than 7,600 freshwater lakes, ponds and reservoirs. The inland waterbodies supply us with drinking water that comes straight to our faucets – that we share with over 200 species of neighboring fishes. In knowing that the entire earth is made of only 3% fresh water, we should consider ourselves blessed. So, this week when you make use of New York’s water, (ie. flush the toilet, shower, wash the dishes, brush your teeth, etc) give thanks and give love to the Empire State.
The DEC's Logo
The Hudson River Estuary logo depicts an Atlantic sturgeon, the Hudson’s largest fish. It highlights the estuary’s critical role as habitat for valuable fish and wildlife and the need to be vigilant in protecting this natural heritage. Through a partnership involving the DEC, the New York State Department of Transportation, the New York State Thruway Authority, and the New York State Bridge Authority, the logo appears on signs where major highways cross tributaries of the estuary. It reminds travelers that these streams are intimately connected to the mainstream, and that the health of the Hudson depends on the health of its watershed.
