Abstract
In this study vessels from 13 Major shrimp ports were surveyed
to determine the cost and earning structure for Gulf shrimp
vessels. This information was combined with effort data for a
sample of vessels spending 50 percent or more of their time on
. the Tortugas shrimp grounds.
Using both these series of data, broken down into vessel size
categories and specifying the distribution of landings between
three Florida ports, a linear programming model was developed
for the express purpose of determining the optimal distribution
of vessels between ports based upon the effort patterns, the
•
distribution of species and the cost components of vessel
operations.
Using constraints based on various assumptions results were derived
which suggested considerable differences from current port use
patterns. Social benefits derived from their application demonstrate
the value of this technique.
