To establish criteria for selecting and solving mathematical models that predict and maximize sustainable fishery yield relative to data collection costs.
Evaluated modeling frameworks ranging from simple equations to complex population dynamic systems based on input requirements and predictive accuracy.
Derived model parameterizations and component terms using deduction, joint regression analysis, catch-effort weighting, and modified tag-recapture methodologies.
Simpler models required minimal input but exhibited poor predictive reliability, whereas complex models delivered greater population insight at the expense of requiring diverse, high-volume data arrays.
Accurate model solutions required operational modifications, including weighting catch-effort data to prevent gross errors and adjusting scale sample sizes for schooling behavior and regenerated scale centers.
