Hightower, Joseph E. and William H. Lenarz (1989). Using GENMOD to Develop
Harvesting Policies for Multiaged Fish Stocks. American Fisheries
Society Symposium, 6:209-210.
Program GENMOD is a microcomputer based simulation program that applies
an age structured population model to problems of optimal harvesting policy.
It can be used to explore alternative harvesting policies and determine the
policy that best satisfies conflicting objectives of fishery management. This
public domain program is written for IBM PC and PC compatible systems.

Common Fishery: A New Methodology." J. Fish. Res. Board Can.,

Optimal harvest rates for mixed stocks of fish are calculated using
stochastic dynamic programming. This technique is shown to be superior to the
best methods currently described in the literature. The Ricker stock
recruitment curve is assumed for two stocks harvested by the same fishery.
The optimal harvest rates are calculated as a function of the size of each
stock, for a series of possible parameter values. The dynamic programming
solution is similar to the fixed escapement policy only when the two stocks
have similar Ricker parameters or when the two stocks are of equal size.
Normally, one should harvest harder than calculated from fixed escapement
analysis.

People Catch More Fish than Others." Canadian Journal of
Fisheries and Aquatic Science 42:2-13.
Most fisheries problems arise from a failure to understand and manage
fishermen, and that the study of fishermen should be a major part of fisheries
research. The dynamic behavior of fishing fleets can be broken into four
components: investment, movement, catching power, and discarding. The
literature in each area is reviewed and the needed research described. The
second part of this paper examines the causes and consequences of individual
variation in catch in a commercial purse seine fishery and a recreational hook
and line fishery. It is shown that the catch is highly concentrated in the
recreational fishery with a small proportion of frequent anglers catching a
large portion of the fish. Catch is more equitable distributed in the purse
seine fishery. The consequence of individual variation includes the
observation that small annual bag limits in the sport fishery could reduce the
total catch significantly while leaving most anglers unaffected and the fact
that buy back of the most successful vessels would reduce the commercial catch
by relatively little.

Scientists and decision makers involved in fisheries management will
always be faced with uncertainties and risks, yet decisions have to be made.
We discuss seven sources of uncertainties and illustrate how these have
affected the success or failure of past decisions in fisheries management. We
then describe how scientists should incorporate information on uncertainties
into the advice given to decision makers by using the formal techniques of
decision analysis and statistical power analysis. Despite the limitations of
quantitative techniques, these methods are the best way of informing decision
