  2. Abstract • To restore the Bronx River to a clean body of water. • To restore and replenish disappearing species by reintroducing oysters.

  3. Vocabulary • Oyster: Marine mollusk having two rough irregular shells that use filter feeding as their primary way of retrieving nutrients. • Fresh Water: Water that contains little to virtually no salt, usually inland water such as ponds, lakes, or streams. • Salt Water: water containing large amounts of salt; seawater. • Brackish Water: Slightly salty water; water that is a mix of salt water and fresh water.

  4. Materials www.dnr.state.md.us www.knysnaoysters.co.za antares.in2p3.fr www.pikeplacefish.com

  5. Procedures • Fill a net bag with oyster shells or manmade substrates. • Tie closed with a plastic twist tie. • Place 2 oyster bags into a crate. • Place 3 to 4 bricks into the crate for sufficient weight • Lower the crate down to the bottom of the river, connected to a marker buoys.

  6. Procedures Contd. • Lift crates up from the river floor where the marker buoys are found. • Remove bricks from the crate to ease the weight. • Cut out the oyster bags out of the crate. • Remove about 10 % of the shells in the bag • Observe and record what organisms are living inside the bag or inside the crate.

  7. Introduction to Oysters: Basic Facts • Filter Feeders • Soft body animals that live in two protective shells • Create habitat space for other organisms • Live between 8 to 25 years • Mature fast • Can be found between 30 to 80 meters below the surface • Require a hard surface to live on

  14. Conclusion • The population of fish drastically decreased, however the Bronx River seems to be “stabilizing” as compared to previous years. • Oysters are an important part of the river, the areas where oysters are found have a wider variety of creatures living there. • By cutting down on the water usage you can help decrease the pollution in the water. • Water monitoring results suggest, by restoring the oyster population the Bronx River will return to a more natural and healthier state.

  15. Future plans • To continue monitoring the oyster reef every month. • To re-launch the oyster garden project that was started in the summer 2005. • To also replenish the native fish populations.
