Allocation modeling tools were developed in previous PFRP-sponsored projects to measure the economic consequences of alternative regulatory policies in fishery management decision-making. Chakravorty et al. developed an allocation model of the Hawaii longline fishery incorporating spatial and monthly distribution of effort and fish stocks (see Chakravorty project). This model was tested by evaluating the effects of regulatory policies including area closures and taxation. A multilevel and multiobjective programming model (MMPM) developed by Leung et al. is also an allocation model (see Leung project). Pan et al (1999) demonstrated the use of MMPM to evaluate the impacts of closing 50-70 miles around the main Hawaiian Islands to longline fishing in 1991, such as profit loss and changes in spatial and seasonal allocation of effort, optimal fleet mix, and use of fish resources. As such, both models can be used to evaluate time-area closures, inter alia, but none is sufficient at present.
Neither model is completely satisfactory in analyzing a range of potential management measurements. Especially, the area designations - the five concentric areas in the MMPM or 5° square in Chakravorty's model - are too large for current regulatory issues where the ranges of various policy options may differ by 1° square. Since area closure is a common practice in fishery management, it is necessary to modify the allocation models by incorporating a flexible area classification to meet the unique management needs for the Hawaii pelagic fishery.
Project researchers will address this critical element while incorporating the advantages of the existing allocation model to meet the specific needs of fisheries management in Hawaii. Researchers plan to modify Leung's MMPM in several ways:
