History of the Bay (cont.) • The bay has been used for fishing for thousands of years. • The word Chesapeake means in Indian, “Great Shellfish Bay”. • You can catch Rockfish, Bluefish, Flounder along with many other fish species. Bay Geography • The Chesapeake covers 64,000 square miles. • Tributary rivers include the Susquehanna, Patuxent, Potomac, Rappahanock, York and James. • Chesapeake waters flow into the Atlantic Ocean at Hampton Roads at the Bay's southeastern end. Bay Geography (cont.) • The length of the Bay is about189 miles. • It is about 4 miles wide near Annapolis, Maryland. • It is 30 miles at its widest, near the mouth of the Potomac River. Bay Flora 1. Sea Grass 2. Phytoplankton 3. Sea lettuce Plant 1 • Bay grasses improve water quality and provide food and shelter for animals. • 16 species of underwater grass are found in the Bay. • 64,000 acres of grasses were in the Bay in 2003, much less than the year before. Plant 2 • Algae (Phytoplankton) are small, microscopic plants. • They are photosynthetic, and produce their own food from sunlight. • Phytoplankton are a primary producer of the oxygen we breathe. Plant 3 • Sea Lettuce (Seaweed) are found in brackish and higher salinity waters of the Bay. • When seaweed overgrows, it can reduce oxygen for other organisms. • It grows in waters that are nutrient-rich or polluted. Endangered Flora Species 1. American Lotus 2. Tawny Cottongrass Bay Fauna 1. Blue Crabs 2. Striped Bass 3. Blue Fish Animal 1 • Blue Crabs or “Callinectes Sapidus” are ten-legged crustaceans. • It walks sideways and defends itself with sharp pincer claws. • The crab's favorite food are bivalves, but when scarce, cannibalism increases. Animal 2 • Rockfish, Striped Bass or “Morone Saxatilis” hatch 29 - 80 hours after fertilization. • They are light green, olive, steel blue, brown or black. • They get a name from the seven or eight dark, stripes along their sides. Animal 3 • Bluefish or “Pomatomus Saltatrix” or Snapper are found all along the east coast. • They migrate north in the spring and and south in the fall. • They travel in groups or “schools”. Endangered Fauna Species 1. Marine Turtles 2. Bald Eagle Bay Industry Blue Crabs Oysters Menhaden Industry 1 • Our bay has been the largest producer of Blue Crabs in the country. • Blue Crab harvests have been going down since the early 1980’s. • The reasons are overharvesting, disease and the loss of habitat. Industry 2 • The Bay Oyster harvests have gone down to less than 1% percent of its peak in the 1870’s. • In 1980, the Bay provided the country with 50% of US oysters. • The Bay now provides only 1-5% of oysters. Industry 3 • Menhaden fish are important because they have the ability to filter water. • There is no quota to limit harvests. • Over-fishing for Menhaden is ruining the Bay's most valuable resource. Bay Recreational Uses Fishing Boating Camping Recreational Use 1 • Fishing is a popular recreation on the Bay. • It provides hours of fun for millions of people. • Tourism is an important industry which provides many jobs. Recreational Use 2 • Boating is also a popular Bay recreation. • Boat builders, supplies, sales, marinas, charters, and restaurants are all related Bay industries. • Boat sales are falling. Recreational Use 3 • Camping is another popular Bay recreation. • There are many campsites in Maryland and Virginia. • Events include shows, festivals and fairs which attract visitors, because camping is fun, affordable lodging. Bay Problems/Threats Natural Threats Industrial/Developmental Improper Disposition Problem 1 • The Bay's pollution is mostly from too many nutrients, nitrogen and phosphorus. • These elements effect the food chain and ecosystem. • When the delicate balance is upset, animals and plants die. Problem 2 • Other pollutants are toxic chemicals, air, and landscape changes. • Wetlands are very fragile, but vital to the world’s ecosystem. • Industry, property developers and lawmakers don’t always consider the value of our Bay. Problem 3 • Sedimentation involves particles carried off land and into waterways. • Household and lawn care products in drains don’t help the problem. • Improper disposal of auto products also plays a part. Bay Solutions Study Action Awareness Solution 1 • Studies for controlling nutrients, nitrogen and phosphorus should be made. • Laws, use guidelines and monitoring could play a bigger part. • Education should be key for all who enjoy the Bay. Solution 2 • Vote for those who consider the Bay, more than potential revenue in development of our shorelines. • Report dumping or activities which threaten your Bay community. • Your family can increase awareness of materials you use everyday. Solution 3 • Think of our beautiful Bay and continue to increase your awareness of possible threats to it. • Share what you learn with family and friends. • Walk on the beach, collect shells, and watch the Bay shoreline closely, whenever you can.
