Title: Describe aquatic inventory/sampling methodologies.
Course: Introduction to Natural Resources and Ecology Systems (18504) > Section: Managing Aquatic Resources

Description should include

- information about the length, weight, age, and sex/maturity of fish
- techniques for fish preservation
- the use of a seine net for aquatic sampling
- comparisons of various methods of aquatic sampling
- examination of the Virginia Save Our Streams methods (e.g., pollution tolerant, somewhat pollution tolerant, pollution intolerant benthic macroinvertebrates)
- water quality measures (e.g., pH, dissolved oxygen, alkalinity, nitrates, nitrites).

Process/Skill Questions:

- Why is inventory sampling important?
- What are the similarities and differences between passive and active methods of collection?
- How are unwanted fish removed from an area?
- How can silvicultural activities affect aquatic ecosystems?
- Why are benthic macroinvertebrates an indicator of water quality? How do fish species correlate to benthic macroinvertebrates?
- How do turbidity and algae affect the fish population?
- Why is determining water quality important?
- Why should one use both chemical and benthic macroinvertebrates together to determine water quality?
