The Columbia River in the Pacific Northwest region of the U.S. is home to the greatest hydroelectric system in the world. Its dams provide 75 percent of the power needs of nearly 10 million people. But the dams also create numerous obstacles to the survival of what was once the...
A great deal is known about economic and social adjustments in modern societies, but the two are not well integrated in social science literature. The unique biological conditions in the fishery further complicate decision making at both the micro and macro levels. An assessment is made of how well current...
Restoring wild salmon runs to the Pacific Northwest is technically challenging, politically nasty, and socially divisive. Past restoration efforts have been largely unsuccessful. Society’s failure to reverse the continuing decline of wild salmon has the characteristics of a policy conundrum: nearly everyone supports, abstractly at least, restoring salmon runs; considerable...
Herring is an important stock as bait for lobster fisheries and a component of the food web of the Northwest Atlantic Ocean. However, herring is very vulnerable to environmental variables such as temperature, food supply, and to the type of sediment on the bottom floor. Egg and larval stage herring...
In this paper, we use a common renewable resource model with stochastic growth to obtain three main results. First, we demonstrate that predictions of poor future environmental conditions lead to lower desired escapement (i.e., low remaining resource stock in place after harvest) and higher current harvest. At first glance, it...
A new evidence for the regime shift has been found as to the tuna populations in the northwest Pacific to show that the regime shift is the universal principle throughout fish groups not only at lower trophic levels but at higher levels. The regime shift has been driven by the...
Two developments: investigation of the relationship between climate and the size of small Pelagic fishstocks, and the extension of this relationship to include its impact on economic activity indicate the importance of specifying the linkage among changes in the environment, a profitable and stable industry and conservation of the resource...
Many records provide the bases for a clearer understanding of the roles of climate regime shifts and short-term perturbations in ecosystem dynamics, hence fisheries responses. Too few have taken the long view of the role of humans in this "Grand Fugue". As one of many predators, it is imperative that...
This paper considers the costs of fisheries management. It starts by reviewing the costs of fisheries management in Iceland, Newfoundland and Norway. The outcome of this study, as well as information from other countries, indicates that fisheries management costs are generally quite substantial relative to the value of landed catch....
This paper reports on a study of Icelandic government expenditures on fisheries and fisheries management during the period from 1990 to 1996. This study is a part of a joint Canadian, Icelandic and Norwegian project attempting to estimate consistently government expenditures on fisheries and fisheries management in these three countries...
