Fisheries Management Systems:Objectives and Performance
A Guest Lecture Prepared for the
United Nations University Fisheries Training Program
Reykjavik, Iceland
Gunnar Knapp
Professor of Economics
Institute of Social and Economic Research
Anchorage, Alaska USA
January 2013
One of the major inherent challenges of fisheries management is multiple and often conflicting objectives.
What do YOU PERSONALLY consider to be the most important objectives of fisheries management?
• (to get reelected)—do do things the public approves of . . . (short time horizon)
• Create jobs; maintain employment• Sustain the fishery• Wealth generation• Feed the population• Maximum economic benefit• Environmental/• Effiiency
Here are some fishery management objectives which I consider important, and which other people also describe as important
Objective Questions we could ask to evaluate performance
Resource protection
How well does the system protect fish resources and the environment? How effective is it at preventing overfishing? How well does it promote sustainability of fish and other resources for current and future generations?
Economic efficiency
How well does the system promote economic efficiency in the utilization of fish resources? How well does it keep costs low and the value of fish products high? How successful is it at generating economic benefits from fish resources?
Fairness How “fair” is the management system? To what extent does it promote communities and cultural traditions?
Simplicity How easy is the management system to understand and to implement? How much does it cost to administer? How effectively can it be enforced?
How important do YOU consider resource protection as a fisheries management objective?
A. Very important
B. Somewhat important
C. Not very important

MY HYPOTHESIS:
There is no “perfect” fishery management system
• No system performs “best” with respect to all objectives• Systems that perform well with respect to some objectives may
perform poorly with respect to other objectives
Let’s find out if YOU agree with my hypothesis.
• We will describe and discuss (up to) six types of fishery management systems.
• For each management system, I will briefly describe the system• Then I will ask YOU to discuss how well or poorly you think the
system performs with respect to each fishery management objective• Then I will ask YOU to use your clickers to rank the performance of
each system with respect to each management objective• At the end of the lecture, we will review how YOU ranked the
performance of these management systems– Do YOU think any system is “best” for all objectives?– Do YOU think that systems that perform well with respect to
some objectives perform poorly with respect to other objectives?
Some challenges we face in our discussion . . .
• We are talking about a very big set of questions!• You may have limited familiarity with some of these management
systems• For any given type of management system, there is a very wide
range in the specific ways they work and how they perform– The devil in the details– Clearly, we are over-generalizing!
• We don’t have much time
If we really wish to seriously evaluate the performance of different kinds of fisheries management systems, we would need to:
• Divide management systems into a greater range of types of systems
• Systematically gather evidence about their actual performance• This would be a major and challenging research task
So our discussion today is only a simple exercise to get you to begin to think about different management systems and how you might evaluate
their performance.
Six broad types of fisheries management systems
I HOPE WE CAN AT LEAST DISCUSS THESE FOUR SYSTEMS
• Unregulated open access• Regulated open access• Limited entry• Individual catch shares
IF WE HAVE TIME WE CAN ALSO DISCUSS THESE SYSTEMS:
• Group catch shares• Fisheries self-governance

Unregulated Open Access
Questions Answers
Who can fish? Anyone
When, where and how can they fish?
Any time, anywhere, any way they wish
How much can an individual fisherman catch?
As much as he can
What limits the total catch?
When fishermen stop fishing—which is driven by resource and economic conditions. Typically, they keep fishing until it’s no longer profitable.

OTHER: Many countries have licensing systems; it depends on the fishery—if it is valuable, it depends on the value of the fishery;
Can be mixed up between sysbsistence and commercial; may favor commercials; when you restric entry, you are looking for those who are fishing as a busness, you may turn away from those fishing for subsistence

• No system performs “best” with respect to all objectives• Systems that perform well with respect to some objectives may

DID YOU AGREE?
My conclusion . . .
For any society, the “best” fishery management system depends upon the society’s
objectives as well as the specific circumstances of the society, the fishery, markets,
and technology.
