The recent advent of agent-based modeling (ABM) and the availability of software platforms for its implementation offer a powerful alternative to model the spatio-temporal behaviors of a fishery with the consideration of heterogeneity and interactivity. This paper describes a prototype agent-based fishery management model of Hawaii’s longline fishery. The model simulates the daily fishing activ...

Variability is an inherent characteristic of neritic fisheries. This is usually associated with both heavy fishing and changes in environmental conditions. Consideration needs to be given to the biological, physical and human components of the management system. This includes controlling the type, size and amount of fish harvested; trying to respond in a timely manner to events in the fishery i...

TAC, total allowable catch, is always setting to be the goal of fishery management. No matter what TAC is taken to be the goal of fishery management, some fundamental limitation of TAC is required. Generally, dome shape is used to express the relationships between the biomass and net production. There is unique point of biomass having the maximum net production (BMNP). This paper attempts to sh...

During the past 12 years fishery managers responsible for federal fisheries off Alaska have developed and implemented three new fishery management limited access/quota share programs in place of traditional open access management. The three limited access programs are unique but each provides for the allocation of quota shares to individual participants in the halibut and sablefish longline fis...

Ichthyoplankton data provide a base for research into population dynamics of major fishery species. Information on ichthyoplankton ecology forms an important component of stock assessment and fishery management plans. Also, nursery areas are important regions for the recruitment success of fishery stocks and as such, conservation of these areas is a key part of fishery management. Temporal dist...

Related Projects (if any) 1. 2004 ~ present: A total of three fishery experts were dispatched to the Department of Fisheries. Following the assignment of a fishery technical adviser in 2004, a fishery administrative advisor was assigned in 2008 to assist in managing and maintaining this project. 2. 2005: One technician was dispatched to receive training in freezer maintenance in Japan. In addit...

The Sustainable Fisheries Act of 1996 and the amended Magnuson-Stevens Fishery Conservation and Management Act elevated habitat and conservation as priorities in federal fisheries management. In particular, the Essential Fish Habitat (EFH) amendment to the Magnuson-Stevens Fishery Conservation and Management Act establishes guidelines to assist fishery managers in the description and identifica...

BACKGROUND Scuba diving fishing, predominantly targeting sea cucumbers, has been documented to occur in an uncontrolled manner in the Western Indian Ocean and in other tropical regions. Although this type of fishing generally indicates a destructive activity, little attention has been directed towards this category of fishery, a major knowledge gap and barrier to management. METHODOLOGY AND P...

OVERVIEW Eight years of octopus fishery records from southwest Madagascar reveal significant positive impacts from 36 periodic closures on: (a) fishery catches and (b) village fishery income, such that (c) economic benefits from increased landings outweigh costs of foregone catch. Closures covered ~20% of a village's fished area and lasted 2-7 months. FISHERY CATCHES FROM EACH CLOSED SITE Oct...
