The eight fishery management councils established by the Fishery
Conservation and Management Act of 1976 are mandated to manage U.S. marine
fisheries resources occurring in the fishery conservation zone based on the
concepts of maximum sustainable yield and optimum yield. Fulfilling the
mandate requires a thorough understanding of these concepts. It is the
purpose of this paper to present a nontechnical discussion of maximum
sustainable yield and optimum yield to facilitate understanding by the
councils, that are composed largely of laypersons, so that they may carry out
their duties under the Act.

There is no obvious method for relating sample size in terms of numbers
of fishing trips to be sampled to any quantitative measure or index of
efficiency which encompasses the totality of information on size, age, sex
composition, and distribution by time and area or to the estimate of yield per
recruit (YPR). Estimation of the growth parameters and variances as well as
the YPR require nonlinear iterative solutions. Further, given the greater
precision in estimation of the Gompertz growth parameters, considerable
improvement in estimating natural mortality would also be expected using the
same model. The same is true of natural mortality. Pauly (1980) used the
parameters of the von Bertalanffy equation to determine his empirical
relationship. Similar methods using the Gompertz equation would likely result
in both improved accuracy and precision. More importantly, variability in the
parameter estimates is a function of the unknown size (and age) distribution
in the population and the sample. When so little is known, it is too early to
ask and impossible to answer how much better a 20% sample would be than a 10%,
etc. The primary goal of the sampling design proposed here is to obtain a
representative sample of size, sex and age over the study area.
