Ocean Roundup: Big Bluefin Tuna Gain Protection from Fisheries, Commercial Fishermen Quickly Losing Consumer Trust, and More
- NOAA recently made amendments to its bluefin tuna management plan in an effort to reduce the number of bluefin tuna killed by commercial fishing vessels. The new rules say that commercial fishermen cannot catch giant bluefin tuna—fish longer than 81 inches—in the Gulf of Mexico or western Atlantic. NPR
How do you like your oysters? Probably not with a side of fishing line or a plastic bag.
This video, created by Katrin Peters for SOS Plastic, shows a couple on a seemingly romantic date. It’s less appealing, though, when you see what accompanies their dinner:
Part of a global campaign to raise awareness and unite international groups against marine plastic pollution, SOS Plastic aims to show how plastics in the oceans affect the entire world.
Every year we use millions of tons of plastic in packaging, water bottles, single-use bags, fishing line and more. The qualities that are so useful to humans – its durability, light weight, and lack of decomposition – make plastic a dangerous material once it gets into the oceans. Polymers can last for decades, if not centuries, which leads to an enormous accumulation of plastic in the oceans.
In 1992, the EPA found that the majority of the world’s beaches showed some sort of plastic accumulation. You might have seen bottles, bags, or fishing nets washed up on the shore, but the real danger lies in what you can’t see.
When exposed to the sun and water, plastics break apart into tiny pieces, called microplastics. These little bits of trash don’t decompose in the water; instead, they get eaten by plankton then travel up through the food chain. Microplastics carry chemicals at extreme levels that can cause illness in both marine animals and humans when we eat seafood.
Many states and counties are starting to limit or ban plastic bags, like Carmel-by-the-Sea in California. You can help by reducing your plastic use – bring reusable bags to the grocery store or farmer’s market, carry a drink in a stainless steel water bottle, and make sure that when you do use plastics you recycle. Sign the Plastics Pledge today to prevent the ocean from getting trashed.
Imagine you’re in a dimly lit Italian restaurant. Famished, you take the first bite of a juicy eggplant parmesan dinner, and it turns out to be a big hunk of plastic. (Yuk.)
That’s the reality for fish in an area of the ocean known as the Great Pacific Garbage Patch, where fish are mistaking their food sources with a growing amount of floating trash.
Two graduate students at Scripps Institution of Oceanography, Pete Davison and Rebecca Asch, joined the Scripps Environmental Accumulation of Plastic Expedition, or SEAPLEX, where they found evidence of plastic waste in more than 9 percent of the stomachs of fish collected during their voyage to the North Pacific Subtropical Gyre, dubbed the Great Pacific Garbage Patch. The mid-water fishes contained plastic debris, primarily broken-down bits smaller than a human fingernail.
"That is an underestimate of the true ingestion rate because a fish may regurgitate or pass a plastic item, or even die from eating it. We didn't measure those rates, so our 9 percent figure is too low by an unknown amount," said Davison.
Based on these rates of ingestion, they estimate that fish in the intermediate ocean depths of the North Pacific ingest plastic at a rate of roughly 12,000 to 24,000 tons per year, but the real number could be much higher.
Last night a few of us here in New York attended the ninth annual Green Drinks NYC Holiday Party. We chatted with some passionate conservationists at the Oceana booth, and were treated to a presentation by special guest speaker, David de Rothschild.
As you probably know, earlier this year, de Rothschild sailed from San Francisco, California to Sydney, Australia, on the Plastiki, a 60-foot catamaran made out of 12,500 reclaimed plastic bottles. He spoke to the crowd about the voyage and reflected on the problem of plastic pollution in our oceans.
Happy Friday, ocean lovers! Lots of juicy ocean news to review this week.
...The big ocean story of this week was a positive one: the U.S. backed the bluefin tuna trade ban at the upcoming CITES meeting. The Washington Post published a great slideshow of bluefin photos and the New York Times ran an editorial urging the U.S. to convince the EU and others to follow their lead.
...Chile's fishing industry, which produces 4 percent of the world's annual catch of seafood, was hit hard by the recent earthquake. Meanwhile, the country's salmon farms, which are located hundreds of miles south of the quake's epicenter, suffered minimal damage, but have been affected by the slowdown in transportation.
...Turns out the Great Pacific Garbage Patch has a cousin in the Atlantic, hundreds of miles off the North American coast, roughly in the latitudes between Cuba and Virginia. Researchers from Woods Hole found more than 520,000 bits of trash per square mile in some areas.
Over the weekend I attended ScienceOnline2010, a raucous gathering (if conferences can be raucous) of scientists and journalists. I met some great folks, including Miriam Goldstein -- one of my favorite ocean bloggers -- of Oyster's Garter fame. (She also recently joined the salty bloggers over at Deep Sea News.)
Miriam was the chief scientist for last summer's Scripps SEAPLEX expedition to the Pacific garbage patch. As if being chief scientist weren't enough, she also blogged and tweeted the journey. And as she hilariously illustrates in this story from one of the first days of the expedition in the California Current, sometimes science doesn't like to be live. (Apologies in advance for my, um, budding video skills.)
The SEAPLEX expedition received a ton of press attention. So after the session, I asked her, "Has the media overblown the pacific garbage patch?" She said, "Well, yes, in a way. There is no 'island' of trash -- the ocean is homogeneous. But it is also way, way worse than we thought."
Look out for the results of the SEAPLEX expedition later on in 2010.
