                                  1. Climate change and fishing

                                    Climate change is having a profound impact on our oceans and marine life. Its effects are changing the distribution of fish stocks and their food.

                                    Balancing economic and environmental priorities is now even more important to keep our oceans healthy and full of fish for the future - we can only do this by fishing sustainably.   

                                    How does climate change affect oceans and marine life?

                                    93%

                                    of heat accumulated in the Earth’s atmosphere is absorbed by the oceans

                                    , absorbing 93% of heat that accumulates in the Earth’s atmosphere, and a quarter of the carbon dioxide (CO2) released from fossil fuels. The impacts of climate change on our oceans include shifts in temperature, acidification, deoxygenation and changes in ocean currents. 

                                    Given their importance to the planet, it's vital we manage the oceans in a sustainable way. Changes to the ocean mean changes to fish stocks. To manage fishing sustainably requires adapting to whatever issues climate change brings. 

                                    In the past 30 years, Globally,

                                    These changes are impacting marine life. Sudden rises in temperature and acidification can lead to the loss of marine habitats and species. Shifting ocean currents and warming waters are changing the distribution of fish stocks and altering the structure of ecosystems.

                                     

                                    How does climate change affect fishing?

                                    Climate change threatens fish stocks, but also creates new opportunities for fishing. 

                                    Areas in the Tropics are predicted to see

                                    In contrast, areas in higher latitudes, such as the North Atlantic and North Pacific, are seeing increases in the range of some fish species.

                                    网上斗牛游戏These changes bring challenges. To continue to fish sustainably requires adopting new ways of fishing. The fishing industry and governments have found it difficult to agree how best to manage changing fish stocks, particularly if fish are moving across international boundaries or where catches need to be significantly reduced. 

                                     

                                    If climate change affects fish, can I still eat it?

                                    1 to 5 kg

                                    carbon produced per kilo of wild fish

                                    Yes. Try to choose MSC labelled fish and seafood网上斗牛游戏. MSC certified fisheries are well managed and more prepared for environmental changes. These fisheries follow current scientific advice to ensure they catch fish sustainably.

                                    Wild fish is a low carbon food 

                                    Additional good news is that fishing has less impact on climate than the harvesting of other proteins. found that each kg of fish caught produces between one and five kg of carbon. By comparison, red meat production is estimated to range from 50 to 750 kg of carbon per kg of meat

                                    网上斗牛游戏There is also evidence that sustainable fishing helps to reduce carbon emissions by increasing efficiency. For example, increased catches within Icelandic fisheries mean that fishing vessels now make shorter fishing trips, reducing their fuel use and carbon emissions as a result.

                                     

                                    How do sustainable fisheries cope with climate change?

                                    Sustainable fisheries that meet the MSC’s standard for sustainable fishing are well-managed and more prepared for climate change.

                                    These fisheries have effective monitoring and management in place to reduce their impacts on the environment and only catch what is sustainable. Following advice from scientists, these fisheries have pre-agreed plans for responding to likely environmental changes. 

                                    These fisheries show that it is possible to balance economic and environmental priorities to safeguard our oceans and seafood supplies.

                                     

                                    What happens when fisheries struggle to adapt to climate change?

                                    As climate change can affect stocks in unexpected ways, even MSC certified fisheries can experience problems.

                                    网上斗牛游戏Here are two examples of fish stocks affected by climate change:

                                    North East Atlantic mackerel

                                    网上斗牛游戏There has been a rapid change in Atlantic mackerel distribution since 2007.  Stocks have moved northward as sea temperatures rise. 

                                    The change in the movement of mackerel has resulted in disputes between coastal states over how to share fishery resources. With fish moving across geo-political boundaries there is a lack of agreement on how best to manage the stock. 

                                    With no result to disputes, MSC certification for North East Atlantic mackerel was suspended in March 2019. This suspension affects fisheries operating in eight countries. 

                                    网上斗牛游戏The mackerel fisheries have committed to delivering an effective harvest strategy by mid-2020. The MSC is working with partners to support these efforts and encourage a resolution to the dispute.

                                    North Sea cod

                                    网上斗牛游戏Recent declines in North Sea cod populations, have been attributed in part to changing climate. This change has resulted in fewer juvenile cod surviving to adulthood. Having fewer adult fish has made sustainable fishing of the cod stock more difficult. Because of this problem, MSC certification of North Sea cod fisheries was suspended in September 2019. 

                                    The fisheries have responded to this disappointing news by committing to measures to rebuild cod stocks over the next five years.

                                     

                                    What else can be done to protect fish stocks?

                                    Fisheries managers need to adopt more precautionary approaches to secure future fish stocks. But effective fisheries management also requires significant international cooperation by governments. This is a significant challenge for many countries balancing economic and environmental interests. 

                                    网上斗牛游戏Some progress has been made. For example, in July 2015 delegates from Canada, Denmark (for Greenland and the Faroe Islands), Norway, Russia, and the United States signed an

                                    Fish is an important source of food and income for communities around the world. For many people, sustainable fishing is a necessity, not a luxury.
