Title: Managing the Fishery
1Managing the Fishery
- How can we regulate the fishery to avoid problems
of open access?
2Why manage fisheries?
- Otherwise, open access externality of entry
drives value of fishery to 0. - May drive to extinction (or economic extinction)
- Non-extractive values ignored.
- Technology may destroy habitat, harvest
individuals that should not be harvested
(bycatch), etc (another consequence of open
access) - Technology may improve, so management must keep
up.
3How to manage fisheries?
- Depends largely on characteristics of fishery
- Biology status of stocks
- History of extraction
- Commercial vs. subsistence, status of stocks
- Other values (non-extractive, recreational,
fairness, distributional) - Many failures, some successes
4Some management alternatives
- Limits on catch
- Harvest quotas (for whole fishery)
- Individual transferable quotas (ITQ, IFQ)
- Marine reserves (area closures)
- Harvest tax
- Limits on effort
- Season closures
- Ex-vessel tax
- Regulated entry (licenses)
- Regulated efficiency (gear)
- Effort tax
- Internalization of externalities
- Cooperatives
- TURFs
Notice Many of these are property rights
solutions
5Small-scale fisheries
- Many small, multi-purpose boats
- Difficult to enforce regulations
- Local management most successful
- Kinship rights, social pressure
- Mainly limited entry, also gear, some area
closures, etc. Often self-imposed. - New entrants, technology, markets are
attractive can be destructive
6Tax on Catch
TC
Total revenue pH(E) decreases with tax (t) on
catch to (p-t)H(E)
TR
Effort
Efficient fishery OA with tax
OA without tax
Tax on catch reduces open access equilibrium
right tax moves effort level to efficient amount
of effort
7Tax on Effort
TC cE
Total costs increase with tax (t) on effort to
(ct)E
TR
Effort
Efficient fishery OA with tax
OA without tax
Tax on effort reduces open access equilibrium
right tax moves effort level to efficient amount
of effort
8Transferable quotas on catch
- Quota levels must be set at efficient catch level
- Must be transferable among fishers
- Value of quota is effectively the same thing as a
tax on catch - Efficiency requires observation of stock
(difficult)
9Transferable Quotas on Effort
TC
TR
Effort
Issue effort permits
OA without tax
Transferable quotas on effort reduces effort to
efficient level
10Individual Transferable Quotas
- Regulator sets total allowable catch (TAC)
based on many factors. - Distributes quotas (auction, sell at fixed price,
give away based on historical catch, or equal
distribution) - Quota rights can be traded.
- Some systems, buy right to harvest in perpetuity
(as of TAC)
11ITQs and property rights
- Prior to 1976 coastal nations did not have rights
to marine resources in high seas - 1976 Magnuson Act Law of the Sea Grants rights
to coastal nations to marine resources 200 miles
from shore. - But how to regulate within a country?
- ITQs effectively secure property rights to fish
in the ocean. - Lack of property rights is what causes problems
with open access
12Potential problems with ITQs
- Allocation of quotas?
- High-grading incentive
- Enforcement administrative costs
- Most quotas held by largest firms
- privatizing the oceans?
- How set TAC in first place?
- TAC based on imperfectly observed stock
13Alaskan Halibut
- Historically used season closures
- Prior to adoption of ITQ, season 1 day
- Poor fish quality, excessive investment for
harvest, frozen most of year. - ITQ adopted 1995 free allocation to fishing
vessels based on historic catch. - Debit cards, fish tickets for enforcement
- A success, longer season, higher profits, more
fish, bigger/better quality fish
14Cooperatives/Cooperativas
- Often devise own rules social pressure to
abide. - Have exclusive rights to areas, self-enforce.
- Federal management supercedes - bargaining
process with feds to determine management - TURFs Territorial User Rights (spatial property
rights) - Good when few spatial externalities

17Resource Concessions
- Give exclusive access for 20 years
- Good chance of renewal if stewardship can be
proven - Same principle in reauthorization of MSFCMA
(Magnusson) - Reluctant to relinquish control? Make property
right insecure - This induces the wrong behavior.
18Economics of Marine Reserves
- Marine reserves implemented for a variety of
reasons - What are their economic impacts?
- Could reserves ever increase rents to a fishery?
- YES! E.g.
- Source/Sink
- Increasing returns to scale (fecundity)
