Sustainable Fisheries and Aquaculture

Social Constraints and Solutions for Progressive Development of the Nation’s Offshore Aquaculture Industry
This project seeks to identify and analyze the social obstacles (constraints) to developing a domestic offshore aquaculture industry.

Forecasts and Adaptation of Tuna Fisheries in Response to El Niño Southern Oscillation
Because of the sensitivity of tuna fisheries to temperature, medium and long-term climate changes create potential challenges for future catch and fishery sustainability.

Efficiency Costs of Restrictions in Tradable Permit Programs: Analysis of the Alaskan Halibut and Sablefish Individual Fishing Quota System
The Alaskan halibut and sablefish fishery is currently managed under a “catch-shares” program, known as an individual transferable quota (ITQ).

Quantifying the roles of environmental variability and the portfolio effect in the population dynamics of the Sacramento River Fall Chinook salmon stock
In 2007, low returns of Sacramento River Fall run Chinook (SRFC) to spawning grounds prompted the closure of the state’s largest salmon fishery.

Developing a new ecosystem-based management approach: using ecosystem models to calculate a better estimate of population scale for single-species models
The single-species models used to manage quotas for individual fishery stocks rely heavily on estimates of population “scale” (abundance).

Quantifying the interactive effects of ocean acidification, temperature change, and fishing behavior on population dynamics and management decisions
Ocean acidification (OA) and changing temperatures could alter the spatial distribution and sustainability of marine invertebrate populations, including for commercially and ecologically important

Propagation of Environmental Variability Across Trophic Levels: How Biological and Ecological Factors Influence Sensitivity of Communities to Climate and Fishing
Climate change may exacerbate year-to-year fluctuations in fish stock sizes, and if this occurs, managers will be faced with new challenges.

Realistic Behavioral-Physical Models of Connectivity for a Network of Marine Protected Areas
Many species of marine crustacean larvae are able to migrate vertically in the water column to avoid surface flows that may carry them away from their preferred developmental or settlement habitats

Match-Mismatch in the Timing of Hatchery Chinook Salmon Releases and Favorable Ocean Conditions
California’s commercial salmon fishery is in trouble and what remains of the fishery is sustained by hatchery-born Chinook salmon from the Sacramento-San Joaquin River system.

Sustainability and Fine-Scale Management of a California Sea Urchin Fishery and the Ecology of Exploitation
A small group of commercial urchin divers has long expressed interest in developing community-based, co-management of the red sea urchin fishery.
