Debate Prompt: Too Few Fish in the Sea
March 3, 2013, The New York Times
Meanwhile, there is growing concern about what is sustainable, or even identifiable.
Is there a way to meet consumer demand for quality seafood and protect threatened marine life at the same time?

A blend of common sense and creativity will be critical to meeting demand for seafood while protecting the species and places we care about.
One example is marine protected areas. The logic makes sense: if you stop catching fish in a particular area, they grow larger and reproduce, and the population becomes more abundant. And as fish populations recover, local marine ecosystems are able to bounce back, and their abundance spills over to surrounding waters. For instance, if we protect spawning grounds and critical nursery habitats like coral reefs, sea grasses and mangroves, then over the longer term we will see more lucrative fishing outside those protected areas.
This is just one piece of the solution, though. We must look at how fisheries are managed and how fish are caught. Fisheries science can help determine how much catch a fish stock can sustain year after year -- exceed the limit, and future harvests will be smaller. The Marine Stewardship Council has established standards for sustainable fishing and seafood traceability. And World Wildlife Fund's Smart Gear competition has fostered technology innovations that reduce bycatch of sea turtles, seabirds and other marine species. One simple but effective innovation is the use of circle hooks to reduce turtle bycatch. Once again, it's about creativity and common sense.
And if balancing the needs of people with those of the ocean is our end game, we should create the incentives to encourage fishing and consumption for long-term management. More than a billion people around the world rely on fisheries for food and income. Promoting stewardship through rights-based management - both for small and large-scale fisheries - will help us achieve the balance we need.
If we bring the right tools to the table we can ensure healthy and productive oceans forever.
Give Fish a Refuge: Partition the Sea
By Callum Roberts, professor of marine conservation at the University of York, England, and the author of "The Ocean of Life: The Fate of Man and the Sea."
Almost 400 years ago, Captain John Smith, the founder of the Jamestown colony, wrote dramatically about the wonderful fishing off the coast of Virginia, in particular the "large-sized fish called Hallibut":
Some are taken so big that two men have much a doe to hall them into the boate; but there is such plenty, that the fisher men onely eate the heads & fines, and throw away the bodies.
Such a catch would not happen today, because most giant fish are long gone.
The halibut was an early casualty of the intensification of fishing in North America, and had become a rarity by the mid-19th century. It has since been joined in aquatic obscurity by a lengthening list of unfortunates: Atlantic wolffish, Acadian redfish, barndoor skate and smalltooth sawfish, to name four. Their misfortune was to grow large, mature late and have long lifespans, a lethal combination in the face of industrial fishing. If you kill indiscriminately, as many fishing methods do, you create winners and losers.
The lions and elephants of the sea dwindle and yield to the rats and cockroaches. Since ocean rats and cockroaches, like flounder and prawns, still taste pretty good, we carry on fishing hard to the point where the giants of old are pushed to the edge of extinction. Only a draconian cut in fishing would bring them back, which would most likely mean extinction for the fishing industry.
The solution is to place some areas off-limits to fishing, about a third of the sea. Within these refuges, fish could once again thrive and grow into toothsome behemoths, and ocean currents would carry their abundant young into surrounding seas to replenish fishing grounds. Marine reserves allow us to have our fish and eat them too.
