  3. Georges River Catchment The Georges River Catchment is 196km2 . It is home to many different species of aquatic animals as well as birds. Some of these species include: pelicans, crabs, prawns/shrimp, cormorants, bream, blackfish, oysters, shags, plankton and many others.

  4. Plankton is a tiny microscopic animal, and one species of it looks like this: We watch the plankton and other species swim around in less than a drop of water! There are many species of plankton in the ocean. Plankton is used for science testing. To collect plankton, you need a very fine net, like this: The only way to view a plankton is under a microscope, like these people are.

  5. Water Quality Testing When we tested the water, we tested for Temperature, Phosphates, Dissolved Oxygen, Turbidity and acidity.

The diagram to the right includes some of the features of the Blue Swimmer Crab. Below is a simple food chain of the Georges River.

  8. Fish dissection When we dissected a fish we either dissected a bream (carnivore) or a blackfish (herbivore). Herbivore fish eat sea grasses and other sea plants. Carnivores eat other fish and molusces. • When we cut open the fish, we started at the anal hole and cut up to its teeth or its mouth. We then cut down to the end of its tail, and pulled the fish open. Some guts (organs) that we found were: • The stomach 6. The bladder • The heart 7. The air bladder • The kidneys 8. The intestines • The egg sac 9. The liver • Gills 10. The lateral line
