One of the significant challenges to using information and ideas generated through ecosystem models and analyses for ecosystem-based fisheries management is the disconnect between modeling and management needs. Here we present a case study from the U.S. West Coast, the stakeholder review of NOAA’s annual ecosystem status report for the California Current Ecosystem established by the Pacific Fisheries Management Council’s Fisheries Ecosystem Plan, showcasing a process to identify management priorities that require information from ecosystem models and analyses. We then assess potential ecosystem models and analyses that could help address the identified policy concerns. We screened stakeholder comments and found 17 comments highlighting the need for ecosystem-level synthesis. Policy needs for ecosystem science included: (1) assessment of how the environment affects productivity of target species to improve forecasts of biomass and reference points required for setting harvest limits, (2) assessment of shifts in the spatial distribution of target stocks and protected species to anticipate changes in availability and the potential for interactions between target and protected species, (3) identification of trophic interactions to better assess tradeoffs in the management of forage species between the diet needs of dependent predators, the resilience of fishing communities, and maintenance of the forage species themselves, and (4) synthesis of how the environment affects efficiency and profitability in fishing communities, either directly via extreme events (e.g., storms) or indirectly via climate-driven changes in target species availability. We conclude by exemplifying an existing management process established on the U.S. West Coast that could be used to enable the structured, iterative, and interactive communication between managers, stakeholders, and modelers that is key to refining existing ecosystem models and analyses for management use.

Spawning Biomass

It is often important to estimate the abundance of a fish stock when the stock is somewhat depleted. For pelagic species this presents great operational difficulties, because adult surveys may be prohibitively expensive and time consuming. Here we introduce a method for estimating the spawning biomass of a stock by means of egg or larval surveys. In particular, we develop a series of models for presence-absence sampling of eggs or larvae and show how presence-absence data can be used to estimate adult spawning biomass. The models are based on an underlying probabilistic description of the aggregation of eggs or larvae, a search process, and a description of habitat structure. Methodologies are given for estimating the distribution of the size of the spawning biomass from presence-absence data. A case study of sardine is used to justify a number of the assumptions. The methods are applied to a 1985 survey for sardine eggs and are compared to an alternative method based on egg production.

Benthic Resources

The Humboldt Current, one of the most productive waters in the world, flows along the Chilean coast with high primary production level. However, living marine resources in these waters are declining due to overexploitation and other anthropogenic and environmental factors. It has been reported that deploying artificial reefs in coastal waters can improve the production of benthic resources. To ensure the sustainability of coastal fisheries in northern Chile this study aims to investigate fishermen’s perceptions on deploying artificial reefs and propose future management measures using Caleta Pisagua as a case study. Interviews of artisanal fishermen regarding four aspects: fishermen profile, fishing activity, resources, and artificial reefs were conducted. Results showed that most fishermen favored the implementation of artificial reefs within the Areas of Management and Exploitation of Benthic Resources (AMERBs). In addition, deploying artificial reefs appears to be socio-economically necessary for the artisanal fishermen whose livelihood is being affected by the overexploitation of coastal fish and because hard substrates essential for benthic resources are in short supply within this administration area. It is recommended that criteria for the deployment of artificial reefs as well as specific management plans for main and secondary species should be developed.

Abstract This study examines Japanese offshore fisheries management by focusing on the possibilities and challenges in implementing co-management of fisheries. Offshore fisheries, characterized by a lack of clear geographical boundaries in fishing grounds and community boundaries in fishery participants, face different challenges than coastal fisheries that are managed by territorial use rights and fisheries cooperative associations. This study examines the current policy and legal framework in offshore fisheries management in Japan and uses a case study of the tiger puffer fishery in Ise–Mikawa Bay to investigate interactions among multiple fishing entities as well as interactions between resource harvesters and managers. We argue that increased participation of both national and prefectural governments in fisheries management contributes to strengthen co-management: yet, a lack of science-based harvest control rules hinders the biological and economic benefits from accruing to the fishery.
