Abstract

The implementation of sector management in New England’s groundfish fishery sparked dramatic changes in every aspect of the industry, forcing an unprecedented level of innovation and adjustment. The switch from the effort controls of days-at-sea to the output controls of sector allocation, prompted primarily by federal mandates, changed everything from a fisherman’s pre-trip planning to business arrangements that get fish from the vessel to the table.

Abstract

In California much work is being done at the local and state levels to mitigate the effects of climate change, and develop adaptation strategies. In particular, California recently released for public comment “Safeguarding California: Reducing Climate Risk” – an update to the 2009 California Climate Adaptation Assessment. In it, decision makers specifically highlight the need to improve understanding of climate risks to biodiversity and habitat, among other recommendations.

Abstract

What is ocean acidification? Every day, the ocean absorbs approximately one-third of the carbon dioxide we put into the atmosphere when we burn fossil fuels and clear land. When carbon dioxide dissolves in seawater, it becomes an acid. This acid is lowering the pH of ocean water. pH is an important vital sign of ocean health, and its rapid change raises a red fl ag. Scientists refer to this shift in ocean chemistry as ocean acidifi cation.

Abstract

In winter 2011-2012 the Alaska Marine Conservation Council (AMCC) sponsored community roundtable discussions on ocean acidification and Alaska fisheries in the fisheries-dependent communities of Homer, Kodiak and Dillingham in southern Alaska.

Abstract

The oceans are dynamic systems. That’s why striking the right balance between use and protection of marine and coastal resources has always been a complicated process, whether its setting fishing levels, reducing by-catch, recovering endangered species, or considering permits for oil and gas exploration. Incorporating climate change into decision-making makes these efforts more challenging than ever before. Increased information, tools and action are essential to meeting these challenges.

Abstract

Growing human populations and changing dietary preferences are increasing global demands for fish1 concerns over fisheries sustainability2. Here we develop and link models of physical, biological and human responses to climate change in 67 marine national exclusive economic zones, which yield approximately 60% of global fish catches, to project climate change yield impacts in countries with di!erent dependencies onmarine fisheries3.

Abstract

The Fifth Assessment Report from the Intergovernmental Panel on Climate Change is the most comprehensive and relevant analysis of our changing climate. It provides the scientific fact base that will be used around the world to formulate climate policies in the coming years. This document is one of a series synthesizing the most pertinent findings of AR5 for specific economic and business sectors.

Abstract

This paper reviews current literature on the projected effects of climate change on marine fish and shellfish, their fisheries, and fishery-dependent communities throughout the northern hemisphere.

Abstract

The impacts of climate change have been demonstrated to influence fisheries resources. One way climate has affected fish stocks is via persistent shifts in spatio-temporal distribution. Although examples of climate-forced distribution shifts abound, it is unclear how these shifts are practically accounted for in the management of fish stocks. In particular, how can we take into account shifting stock distribution in the context of stock assessments and their management outputs? Here, we discuss examples of the types of fish stock distribution shifts that can occur.

Abstract

An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7–9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change on aquatic ecosystems and on fisheries- and aquaculture-based livelihoods are provided in the introduction of this Technical Paper.
