Daniel Pauly’s research over the last 20 has provided much of the foundational theory in modern fisheries management. In 5 Easy Pieces, Daniel Pauly presents his five most influential papers, with a concise history of both the intellectual and human motivations that led to each study. The papers that were included in this volume are: Primary Production required to Sustain Global Fisheries, Fishing Down Marine Food Webs, Systematic Distortion in World Fisheries Catch Trends, Towards Sustainability in Global Fisheries, and The Future of Fisheries.
fish face a tradeoff of where to use their energy, much like the polluted fish in the Lorax by Dr. Suess
Overfishing is most often implicated as the cause of decreasing fish stocks and that makes a lot of logical sense if you’ve ever seen a large commercial trawler unload its catch. But there very well might be another force at work in the precipitous decline in fish stocks worldwide: pollution. The basic premise is that it takes resources to deal with pollutants that normally would be given to growth and reproduction. Through polluting the ocean, we have selected for the fish individuals that can most effectively divert those resources, inadvertently also selecting for smaller fish that reproduce less. That has huge implications for the fish’s population dynamics and potentially total fish stock. More details below the fold…
The problem
Sharks consistently rank near the top of lists of American’s greatest fears. In reality, they have much more to fear from us than we do from them. Because of our actions, many species of sharks are on the verge of extinction. A recent International Union for the Conservation of Nature Shark Specialist Group report shows that fully 1/3 of open-ocean species of sharks are in danger of extinction in the next few decades. Many shark species have had population declines of over 90% in the last few decades.
