  1. OVERFISHING OYSTERS IN THE CHESPEAKE BAY Aaron Natoli Carleton 4/20/14

  2. What is Overfishing • Overfishing is when more fish are being caught and killed faster than they can reproduce.

  3. Origins of the Bay • The Chesapeake (meaning "great shellfish Bay" in Algonquin) • Oyster harvesting has been around since the early 1800’s • It is said that there were so many oysters beds lining the water that it was nearly impossible not to hit one with your boat

  4. Early Oyster Harvesting • There where certain methods of how to harvest oysters in the early years. ( nets, rakes, etc.) • In 1865 oyster dredging became legal. It was a more faster and easier way to collect the oysters. • Drag giant nets behind the boat which scrapes the bottom collecting the oysters • Downfall is that it destroys reefs and beds as well as other species of fish

  5. 1980’S • During the 1980’s oysters where introduced to two deadly diseases MSX and Dermo • MSX- Is a bacterial disease which is transferred oyster to oyster. It is harmless to humans • Dermo- Parasite that travels from dead oysters to live ones same as MSX it is harmless to human health. • These two disease killed a large majority of oysters in the bay and the numbers are still affected today.

  6. Today’s Effects • The oyster population has depleated 98% since the 1800’s and is still dropping. • In 2005, 79,600 bushels of oysters where caught in Virginia.

  7. Illegal Harvesting • Illegal Harvesting has been around since the 1800’s • Unlike legal harvesting there is no set limit to what the fisherman can catch in a day. • Also it was found that 9% of illegal fishing took place in infested dirty water. • This could make hundreds of thousands of citizens sick.

  8. Economic Effects • Overfishing has effected the economy in many ways. • According the the Chesapeake Bay Foundation due to overfishing there has been a 4 billion dollar lose in the past 30 years. • Overfishing also effects restaurants as well as fisherman. • Restaurants: having to charge more for oysters due to the high demand • Fisherman charge the markets more because of traveling out farther in hopes of finding oysters.

  9. Recovery • The Chesapeake Bay Foundation (CBF) has been one of the main contributors to helping bring the numbers of the oysters back. • This organization helped with rebuilding reefs and beds for the oysters • Built with concrete with holes dug in to help house the oysters • Then put in a safe and clean water so they can grow. The state of Maryland has poured more than 50 million dollars into rebuilding the ecosystem.
