This article looks at how fisheries biologists of the early twentieth century conceptualized and measured overfishing and attempted to make it a scientific object. Considering both theorizing and physical practices, the essay shows that categories and understandings of both the fishing industry and fisheries science were deeply and, at times, inextricably interwoven. Fish were both scientific and economic objects. The various models fisheries science used to understand the world reflected amalgamations of biological, physical, economic, and political factors. As a (...) result, scientists had great difficulty stabilizing the concept of overfishing and many influential scholars into the 1930s even doubted the coherence of the concept. In light of recent literature in history of fisheries and environmental social sciences that critiques the infiltration of political and economic imperatives into fisheries and environmental sciences more generally, this essay highlights both how early fisheries scientists understood their field of study as the entire combination of interactions between political, economic, biological and physical factors and the work that was necessary to separate them.

It might seem strange to connect the word hope with the world's oceans. No honest person can deny that the oceans face multiple crises: overfishing, dying coral reefs, acidification, industrial and agricultural pollution, vast rafts of garbage. The oceans bear witness to humanity's worst tendencies. It is therefore a bold effort that seeks to find hope in this litany of despair.In Hope at Sea Teresa Shewry seeks signs of hope in various literary works from around the Pacific region. This (...) book has many attractions. For the nonspecialist Shewry provides a useful introduction to the environmental/cultural discourse of a region that is often forgotten. She provides a good overview of recent literature dealing with the... (shrink)

As the efficiency and reach of global fishing has grown, overfishing has unwittingly undermined the industry’s future while at the same time depriving poor people of a dietary staple. Several problems that most concern the critics of globalization come into play: undermining the power of governments to protect their environments and citizens, an economic system that robs the poor and future generations of basic necessities, and market developments that undercut long term economic and environmental stability. I examine how creative (...) institutional measures could avert total collapse of ocean ecosystems despite the complexity of enacting marine ethics in a globalized economy. I look at companies that work with the Marine Stewardship Council’s criteria as well as more creative measures including revamped marketing and changes in how members of the industry work together in order to encourage long term environmental and economic sustainability.

The impacts of early fishing on aquatic ecosystems were minimal, as primitive technologies were used to harvest fish primarily for food. As fishing technology grew more sophisticated and human populations dispersed and expanded, local economies transitioned from subsistence to barter and trade. Expanded trade networks and mercantilization led to surplus catches becoming tradable commodities. Today, global export fish commodities, including fresh, frozen, cured, and canned fish, are valued at over US$ 100 billion, but commoditization loses the ecological imperative, with (...) class='Hi'>overfishing the result. To sustain global fisheries, human and ecosystem relationships with living fish need to be valued, as fish landed for both food and profit. Toward this end, we propose two decommoditization strategies: (a) valuing cultural property, the intergenerational relationships of people to places, in environmental policy and (b) instituting social subsidies that reward or enable local communities to cooperate in sustaining aquatic living resources, such as with marine protected areas.

Relativity is one of the most overfished streams in the history of science. Albert Einstein has doubtless graced the covers of more monographs than any other scientist—possibly save Charles Darwin—in the decade since the 2005 centenary of his annus mirabilis. I was skeptical that Jimena Canales would be able land new catch from such thoroughly exploited waters. The Physicist and the Philosopher proved that skepticism misplaced. By exploring a decades-long feud that pitted Albert Einstein against the French savant Henri Bergson, (...) Canales shows how relativity intertwined with an intellectual context that has been roundly ignored by historians and philosophers of science and presents one of history’s most iconic scientists in new light.

Aquatic ecosystems are vital to the structure and function of all environments on earth. Worldwide, approximately 95 million metric tons of fishery products are harvested from marine and freshwater habitats. A major problem in fisheries around the world is the bioethics of overfishing. A wide range of management techniques exists for fishery, managers and policy-makers to improve fishery production in the future. The best approach to limit overfishing is to have an effective, federally regulated fishery, based on environmental (...) standards and fishery carrying capacity. Soon, overfishing is more likely to cause fish scarcity than fossil fuel shortages and high energy prices for fish harvesting. However, oil and other fuel shortages are projected to influence future fishery policies and the productive capacity of the fishery industry. Overall, small-scale fishing systems are more energy efficient than large-scale systems. Aquaculture is not the solution to wild fishery production. The energy input/output ratio of aquacultural fish is much higher than that of the harvest of wild populations. In addition, the energy ratios for aquaculture systems are higher than those for most livestock systems. (shrink)
