Happy Monday-est Monday!

Foghorn (A Call to Action!)

This is the final week to get you abstracts in for the International Marine Conservation Congress, the premier ocean conservation conference, coming to you from Kuching, Malaysia this June! We got a cracking good symposium on human impacts in the deep sea and plenty of travel grants available for researchers in need. And, for the first time, we’ll be hosting Make for the Planet, Borneo!

Fog Horn (A Call to Action)

One week left! The deadline for comments on Marine National Monuments and National Marine Sanctuaries has been extended due to overwhelming responses. You now have until August 14, 2017 to leave a comment. Scientists, researchers, explorers, and conservationists with particular ties to the Mariana Trench Marine National Monument can sign on the this letter co-authored by me, James Cameron, and numerous researchers who’s worked has benefited from the Mariana Trench.

A Maine Lobsterman catching a one-eyed bald eagle struggling to swim has got to be a metaphor for something, right?

Six reasons why Menhaden are the greatest fish we ever fished.

Menhaden, Brevoortia tyrannus, is, without a doubt, the single most important fish in the western Atlantic. This oily filter-feeder swims in schools so large that they block the sun from penetrating the water’s surface as it regulates ocean health. Earlier this week, we were greeted by news that menhaden stocks were rebounded, yet despite their near-universal importance in the western Atlantic and Gulf of Mexico, most Americans have near heard of a menhaden.

Let’s fix that. Here are six reasons you should know what a menhaden is.

1. Menhaden go by many names.

The Narragansett called them munnawhatteaug. Colonists called them poghaden, bony-fish, whitefish, pogy, mossbunker, fat-bat. Perhaps most endearingly, menhaden were called bug-heads, thanks to the parasitic isopod that was often found in place of their tongues. They have also been called “the most important fish in the sea“.

PolitiFact calls claims of menhaden declines “Mostly False”, is completely wrong

Despite their small size and plain appearance, menhaden have been called “the most important fish in the sea” because numerous coastal fish species rely on them for food. Although they aren’t typically eaten by humans, there is still a huge fishery for them for bait, aquaculture food, and oil. That fishery has been essentially unregulated, allowing fishermen to take as many as they want. Recently, there’s been a campaign among certain environmental groups to fix this problem and put catch limits in place for menhaden.

I was surprised to see PolitiFact, a non-partisan political fact-checking website, address this issue. I’ve checked PolitiFact pretty regularly for years, and I’ve never seen them cover a topic like this before. They focused on a claim by the Pew Environment Group that “In recent years, menhaden numbers along our coast have plummeted by 90 percent.” While I admit I am not familiar with specific details of menhaden population trends, anyone who has paid any attention at all to the ocean knows that we’re overfishing at alarming rates. According to the UN Food and Agriculture Organization, approximately 1/3 of all global fisheries are depleted or overexploited, many by more than the 90% referenced for menhaden. Shockingly, PolitiFact called the claim by Pew “mostly false”. Their reasoning for this ruling is even more ridiculous than the ruling itself:

The Menhaden of History

Posted on May 13, 2010 by Andrew David Thaler

Menhaden were the most important fisheries throughout American history. When the first settlers learn to farm corn, it was with menhaden that they fertilized the seeds. When the whaling industry reached its height, it was outweighed by menhaden oil. Menhaden ruled the ocean from the middle of the food chain, they were the dominant prey of most large predatory fish. They swarmed the sea in schools several miles long and millions of fish deep. Their huge biomass supported by plankton, they regulated algal blooms, mediated the transfer of primary production up the food chain, filtered the ocean.
