Tribes, Climate Change and Fish Migration
Friday, April 18th, 2008Today’s Nordic News Daily reports that increasing fish stocks and migration of species to new areas are among the consequences climate change is expected to have for fish stocks in the sea.
While the general consensus is that global warming will disturb marine eco-systems, researchers are less certain about the scope of the consequences, it emerged from a conference in Bergen, Norway, on Thursday and Friday.
Just over a hundred delegates from the Nordic Region, the EU and Russia attended the conference and discussed the potential consequences of climate change for fish stocks and fisheries management.
“Cod stocks in the north-east Atlantic will probably grow and expand in a northerly direction, for example. But we don’t know to what extent,” stressed Dr. Randvi Ingvaldsen of the Norwegian Institute of Marine Research.
In general, warmer water will lead to larger fish stocks, but at the same time a number of species run the risk of being wiped out in certain areas. On the other hand, fish species will be able to migrate to new areas as the water temperature rises.
“This might, for example, mean anchovies and swordfish in the Baltic,” said Professor Brian MacKenzie of the Danish National Institute of Aquatic Resources.
“Levels of salt content will also be important in the Baltic, as well as climate change,” MacKenzie reminded delegates. If the salt content falls further, cod in particular will find it difficult to survive.
“Changes in fish stocks’ migration patterns are likely to become a major fisheries-policy issue,” predicted Helga Pedersen, the Norwegian Minister of Fisheries and Coastal Affairs. The current agreements about the geographic distribution of fishery rights between nations will probably have to be revised, which many believe will be a difficult process.
Over the past several years I’ve had a series of conversations on this issue with Russel Barsh of Kwiaht, the Center for Historical Ecology of the Salish Sea and Stuart Harris, Director of the Department of Science and Engineering at the Confederated Tribes of the Umatilla Indian Reservation. Our sense was that, for Indian tribes, changes in the migration of fish stocks will not only raise significant intergovernmental and intertribal legal issues, but very important health, identity, cultural and religious ones as well. Will we need new songs, new stories, new design motifs? Will we need to reexamine our histories to see how we adapted to past changes in climate and see if and how those lessons can be applied today?
To address (not answer) these and related questions, the Confederated Tribes of the Umatilla Indian Reservation and the International Institute for Indigenous Resource Management are sponsoring the Workshop on Adaptive Governance and Climate Change. The workshop will be held at the Wildhorse Resort and Casino in Pendleton, Oregon on August 19-20, 2008. The agenda and other information will be posted on the Institute’s website.
