Essentials of a Good Fisheries Manager
Strong science and quantitative background. A coherent environmental ethic. Knowledge of economic forces. Knowledge of state and federal policies that affect aquatic resources (especially CWA). Ability to communicate with people that may disagree with you or have a very different background. Common sense.

Petty’s Ethic Human Societies depend on services provided by aquatic ecosystems (water, flood control, food, recreation, aesthetics). Our use of aquatic resources must protect the internal capability of aquatic ecosystems for on-going re-creation (i.e., sustainability). Self-sustaining fisheries require naturally functioning ecosystem processes. Fisheries managers should be actively managing to restore and protect natural ecosystem process such that self-sustaining aquatic ecosystems are maintained for the benefit of human society.
