Note: Try putting your trap in different areas (weedy, sandy, rocky, etc.). You should catch different kinds of minnows, small fishes and other living things in different habitats. Where do you catch more? Why? Also, try comparing an area you are rehabilitating to other areas within your shoreline. Habitat can be used by different species during the day and at night.
Note : Use your underwater viewer to study different types of habitat. Be sure to stand still and be quiet. What do you see in areas with weeds? What do you see in rocky areas? What about sandy areas? Look at tree stumps and branches underwater. Can you see differences between these habitat types?
