Analyzing the Technical and Economic Structure of Hawaii's Pelagic FisheryProgress Reports (PDF): FY 2001, FY 2000
The main objective of this project is to determine the technological and economic interrelationships in Hawaii's pelagic fishery using a multi-product dual revenue function approach. A secondary objective is to provide a preliminary test of incorporating these estimated relations into the existing allocation model.
The significant pelagic species landed in Hawaii's markets include:
Conflicts between different fishing fleets (longliners, trollers, handliners), impacts on endangered species, and the possibility of localized overfishing were the basis for regulations for the domestic longline fishery in 1990 and subsequent regulations for longliners under the Pelagic Fishery Management Plan. As an effort to analyze the potential impact of limited entry programs on various Hawaii fisheries, and on the economic performance of various fishing fleets, a linear programming model (LP) of Hawaii's commercial fisheries was developed by the E.R.G. Pacific, Inc. company. This model was subsequently modified and extended by the National Marine Fisheries Service (NMFS). Recognizing the fact that the typical fishery policy problem is characterized by (1) more than one objective or goal that decision-makers wish to optimize, and (2) decision making at fishermen and policy levels, with policy-makers having incomplete control over all variables, Leung et al. (1998) have extended the NMFS LP model into a two-level and two-objective mathematical programming model.
This extended allocation model can assist fishery manages to identify the optimal fleet mix spatially (by area) and temporally (by season) given the estimated amount of fishery resources under various management options. Although fishery incidental catch is considered in the model, the amount and proportion of targeted catch and incidental catch are assumed to vary depending on fleet, target, area, season, as well as total fishing effort based on the average of the trips taken in 1993. Using a fixed proportion of targeted catch and incidental catch for 1993 or any other year may create unrealistic 'corner' solutions in the event that the resource of a incidental catch species becomes binding. The proposed research can resolve the above problem in the present allocation model by providing more realistic technical and economic relationships among the different species in Hawaii's multi-species pelagic fishery. In general, understanding of these interactions is imperative in allocation and management options to better manage the multi-species pelagic fishery in Hawaii.
Year 1 funding for this project awarded in October 1999.
