Analysis of Pacific Halibut with Uncertain Gordon-Schaefer Equation

This paper extends the research and applications of the uncertain Gordon-Schaefer model. We examine two stability criteria for the equation solutions: stability in mean and stability in p-th moment. Then we collect 85 data points from the International Pacific Halibut Commission and analyze the catch data using the uncertain Gordon-Schaefer equation. Through the uncertain hypothesis test, we demonstrate that the uncertain Gordon-Schaefer equation provides an adequate fit. Finally, we establish why the stochastic Gordon-Schaefer equation fails to characterize the halibut catch data effectively.
