RIASSUNTO

Fish population dynamics model is deemed to be effective to grasp the fishery resources in coast, which are the important food supplies for us. However, the influence from complex environmental conditions of coastal sea area is not supposed to be neglected. PDLS model was developed to estimate fish population dynamics where the relationship between environmental fluctuation and biomass change was extracted qualitatively by Optimal Transformation (OT) method from monitoring data. If we are to better understand the dynamics correctly, we must be cautious to find an appropriate formulation method to characterize the kind of relationship for accurate estimation. This study aimed to formulate the relationship between environmental fluctuation and fish population dynamics extracted by OT method from measurement data. This paper suggested restoring real response from the OT results based on the algorithm of OT and using multiple functions to explain the response characteristics. The results indicated that this formulation method was more effective to point out the underlying association from data than existing method and it is potential to find out the mechanism of response and make contribution to estimation on coastal fish population dynamics.
