  • Conduct biological research and investigations to develop and evaluate restoration and protection plans for aquatic ecosystems.
  • Use statistical methods to design experiments and sampling strategies.
  • Analyze water development projects to identify their potential impact on fishery resources.
  • Analyze proposed projects to determine potential impacts to areas which serve an important biological function, such as food chain production, providing a general habitat and nesting area, spawning, rearing and resting site for aquatic species.
  • Use a variety of software packages such as database programs, and spreadsheet programs in performing data analyses, "real-time data summaries," and statistical evaluations.
