Presentation Transcript

  1. Trout in the Classroom

  2. We will: • raise trout from eggs to fry • monitor tank water quality • Study trout stream habitat • learn about water resources and conservation

  3. Brook Trout • Only native trout to PA • They need low temperature, a lot of oxygen, and excellent water quality

  4. Indicator Species An organism whose presence reflects the environmental conditions They are sensitive to changes in their ecosystem May get sick, die or leave the area

  5. Timeline Egg collection Eggs shipped or delivered to schools

  6. Timeline • We get approximately 300 eggs • They will hatch in 2-3 weeks (called alevin or sac-fry)

  7. Timeline • The fish will begin to swim up and look for food after approx. 1 week (Fry) • When they are 1-3 inches they will be called fingerlings

  8. Adult Brook Trout Color and Markings • Reddish orange on belly and under fins • Yellow spots on sides • Yellow-brown worm-like markings on it’s back • Red spots with blue haloes across each side

  9. Nitrogen Cycle • Feed the fish • Extra food and fish waste turn to ammonia (NH4) • The ammonia changes into nitrites (NO2) • The nitrites change into nitrates (NO3) • Nitrates can poison the fish so you must clean the tank and change the water

  10. Aquarium Jobs • Check and record temperature • Remove dead eggs (later, fish), record numbers • Make water exchanges • Water quality tests, record results • Dust and clean equipment • Clean filter parts • Later, Siphon tank

  11. Nitrogen Cycle
