What is a Fishery?

• Targeted fish population, the aquatic habitat and
  associated species, and people associated with
  the capture and/or other use of the species

EXAMPLE OF A FISHERY

What is Fisheries Science?

• A multidisciplinary area of research, including
  fishing technology, biology, economics, and
  management.
• Obtaining basic knowledge.

14
What is Fisheries Management?

• Applying knowledge gained through basic research
  to manipulate aquatic organisms, aquatic
  environments, and their human users to produce
  sustainable benefits to people.

Essentials of a Good Fisheries Manager

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

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.
