How do you like to make big, complicated decisions? I like to write lists of pros and cons associated with the choice I’m leaning towards. That’s served me well for changing jobs, selling houses and more.
But for complex systems, like fisheries, simply comparing pros and cons of one choice isn’t enough. There are many moving parts in a fishery, and they are interconnected. For example, when fishermen harvest sea scallops, they reduce the overall number of scallops in an area, and change the age and size distribution of individual scallops. At the same time, factors like rising water temperature, availability of food, or quality of habitat can also affect scallop populations, and external factors like the price of scallops or gasoline can influence the intensity of fishing effort. So, changes in a fishery often lead to outcomes that don’t necessarily generate neat bullets you can compare on a balance sheet.
It’s especially challenging to plan for both short and long term changes in a fishery. Most fisheries are managed to accommodate short-term changes that last a few years, like natural fluctuations in population size. But fisheries management today generally doesn’t also consider long-term changes spanning many decades, like warming and ocean acidification, even though we know those changes are gradually tilting the playing field for many marine species.
Secretary of State John Kerry recently hosted the Our Ocean Conference at the Department of State earlier this week. Secretary Kerry invited world leaders, scientists, activists, and ocean lovers to come together to learn more about overfishing, marine debris and ocean acidification. The conference didn’t just focus on the problems of today. Governments, nonprofits and private businesses all offered solutions for tomorrow.
Ocean Conservancy was honored to attend and participate in the conference. Andreas Merkl, our president and CEO, spoke on the panel about marine debris. He echoed the threats plastic poses to marine life and how we can work together to make our seas trash free. Alexis Valauri-Orton, an intern for our ocean acidification program, presented on her travels and how ocean acidification could potentially affect coastal communities all over the world. And I was lucky enough to live tweet all the excitement from the front row of the main room! Below are the major takeaways from the Our Ocean Conference.
Red snapper (Lutjanus campechanus) are one of the Gulf of Mexico’s signature fish. They are extremely popular among recreational fishermen and a prized offering at restaurants and seafood markets, as well as a top predator in the Gulf ecosystem. Recently there has been a great deal of debate about the health and management of this important fish. Ocean Conservancy, along with Pew Charitable Trusts, has released a report about the law that is saving American fisheries, including red snapper. Here are few handy facts about this iconic fish:
Red snapper can grow to about 40 inches, weigh up to 50 pounds and live more than 50 years.
Red snapper begin to reproduce when they are about two years old, spawning from May to October along rocky ledges or coral reefs.
Fertilized eggs float on the surface and hatch within a day. Only a month later, the young fish settle out of the water column in shallow waters, and as they get older, they move to structured habitat where they will mature and eventually move to the deeper waters of the Gulf. Continue reading »

Dr. Jane Lubchenco announced today she is stepping down as administrator of National Oceanic and Atmospheric Administration.
We want to thank Dr. Jane Lubchenco for her tireless work to promote science, conservation and cooperation in all her efforts to ensure a healthy ocean. As the head of NOAA, she has led a forward-looking agency determined to preserve the ocean for generations to come. We are confident she will remain a strong voice for science and conservation.
Ever a teacher, Dr. Lubchenco has been one of the most steadfast champions of science and the need for scientists to become solutions-oriented at a time when restoring scientific integrity is an urgent priority for the country. Under her leadership, NOAA renewed its focus on key ocean issues like ending overfishing, reducing marine debris, protecting the Arctic and tackling climate change and ocean acidification.
Dr. Lubchenco and NOAA were quick to respond to the BP Deepwater Horizon oil disaster and continue to play a pivotal role in ensuring that the Gulf region, including the marine ecosystem, is restored. She was also instrumental in the creation and follow-through of President Obama’s historic National Ocean Policy Executive Order, which created a set of commonsense principles to protect important marine habitat, help clean up our nation’s beaches, and foster emerging industries and jobs.
We wish Dr. Lubchenco well in her new endeavors, and we hope that NOAA, and the rest of the federal government, follows her lead with a cooperative, scientific and ecosystem-based view to solving some of the planet’s biggest challenges. That also means it’s more important than ever that Congress provide NOAA the resources it needs. Superstorm Sandy was the most recent lesson in why NOAA is crucial — their tools, services and information can help us make better decisions to save lives and reduce the risks and costs of future disasters.
I don’t like to see red on a map. It usually means something bad: a hurricane warning, the decline of Arctic sea ice, or as this map shows, the amount of overfishing in 1950 and 2006. Did you click on that overfishing link and check it out? Pretty red right?
Overfishing is bad for fishermen who want to enjoy fishing today, tomorrow, and years from now. Without stable fish populations, there will be shorter or nonexistent fishing seasons – a huge blow to recreational and commercial fishing and the jobs/industry they support. If we don’t end overfishing, then, like Washington Post reporter Brad Plumer says, it’ll be “lumpy jellyfish sandwiches for everyone.”

A hearing was held yesterday on a bill being considered by the House Natural Resources Committee that could improve protections for fish across the globe and for fishermen here in the United States.
The bill, HR 4100, would strengthen enforcement mechanisms to stop illegal, unregulated and unreported fishing – also known as pirate fishing. While this term may conjure up an image of Captain Hook or Treasure Island, pirate fishing poses a serious threat to global fisheries and could jeopardize the successes we have made in U.S. fisheries.
You may be surprised to learn that up to 20 percent of all fish caught worldwide are taken illegally or in unregulated waters – that’s one in every five fish caught. This bill would strengthen the ability of the United States to combat this problem. Continue reading »
