In South Louisiana, Seafood Means Hope

This blog post and photo slideshow was created during OCEANDOTCOMM, an ocean science communication event, and supported by the Louisiana Universities Marine Consortium (LUMCON) The theme of OCEANDOTCOMM was Coastal Optimism. Photos were contributed by our lead photographer, Rafeed Hussain/Ocean Conservancy, with additions from other OCEANDOTCOMM attendees, including Melissa Miller, Samantha Oester, Susan Von Thun, Solomon David, Rebecca Helm, and Alexander Havens.

In many ways, South Louisiana is seafood- a trip here isn’t complete without eating some gumbo, oysters, or crawfish. Only one state (Alaska) lands more seafood than Louisiana’s 1.2 billion pounds a year (as of 2016). As of 2008, one in 70 jobs in the whole state is tied to fishing or related industries. According to the Louisiana Seafood Marketing and Promotion Board, “when you choose Louisiana seafood, you’re ensuring that your purchase benefits an American community and a way of life.”

When we visited Terrebonne Parish, home to nearly 20 percent of all commercial fishing license holders in Louisiana, we found that fishing means more to the people of this community than food and jobs. Here in South Louisiana, fishing is a vital part of the vibrant local culture and community pride. In a region that’s been devastated by hurricanes and oil spills, fishing is also a source of something more important: hope.

Below, you’ll hear what fishing means to South Louisiana’s fishing communities through the voices of a former shrimper, the owner of a grocery store that has served the town of Chauvin for more than a century, and representatives of a local Native American tribe. You’ll also get a glimpse into this beautiful part of the world through a photo slideshow. Together, this paints a picture of communities that have overcome unimaginable struggle, but still look forward to the future, in no small part because of the riches of the sea.

Have you heard the good news about shark populations? Shark population increases are cause for #OceanOptimism

Posted on February 28, 2018February 28, 2018 By David Shiffman
Conservation, Science

Did you know that some shark populations have declined due to overfishing? Did you know that some once-declined shark populations have recovered? If you’re like my twitter followers, it’s likely that you’ve heard the bad news, but have not heard the good news.

Why does this matter?
It’s important to share bad news so that people know there’s a problem, and that we need to act to solve that problem. However, it’s also important to share good news so that people know that a problem is solvable! This idea was behind the birth of the #OceanOptimism online outreach campaign.

Dear Shark Man, do open ocean sharks use nursery areas?

Welcome to  Dear Shark Man, an advice column inspired by a ridiculous e-mail I received. You can send your questions to me via twitter (@WhySharksMatter) or e-mail (WhySharksMatter at gmail).


Dear Shark Man,

I know that sharks that live close to the coast sometimes use “nursery areas” when they are young. Do open ocean sharks also use nursery areas?
Sincerely,
Nosey in North Carolina
