Pettys 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.
