Last December, I sat down to enjoy a pizza pie and draft beer with my friend Neal, a 6-foot, 5-inch, 280-lb. (think offensive lineman), die-hard conservative republican. He was giddy with excitement to talk with me about one of his favorite TV shows, Animal Planet’s “Whale Wars.” Knowing that I’m a tree hugger by nature and a marine biologist by trade, he thought an hour of “Save the whales!” camaraderie was ahead. He was shocked when I let out a long sigh and confessed, “I’m not a fan of Whale Wars.”

Neal was completely deflated. He demanded to know why I didn’t like the show. Shouldn’t I, of all people, be Sea Shepherd’s No. 1 fan? I offered my gripes: It’s outrageously expensive to operate a vessel like Sea Shepherd’s SSS Steve Irwin in the extremely volatile and dangerous environment of intercepting Japanese whaling vessels in the Antarctic — on the order of tens of thousands of dollars a day. Although funds are available to support these operations, the return on investment is unclear. How many whales are actually being saved?

Largest U.S. Shark Fishery: Coming to a School Lunch Near You?

Posted on By Chuck Bangley 8 Comments on Largest U.S. Shark Fishery: Coming to a School Lunch Near You?
Conservation

Spiny dogfish sharks have had a complicated history when it comes to fisheries management, going from hated pest to crashed fishery to conservation concern and now one of two certified-sustainable shark fisheries ever (the other is the Pacific species of spiny dogfish).  The story didn’t end with being certified sustainable though, and recently this fishery has been in the awkward position of keeping itself sustainable while also making sure fishermen can actually sell their catch.  Dogfish quotas have been leaping up annually since the Atlantic fishery was first considered for MSC certification, much to the chagrin of conservationists who would prefer the management plan pay more attention to the life history of these small but slow-growing sharks.  However, these increased quotas, combined with weakening demand in Europe as a result of the economic downturn, have lead to a massive surplus of dogfish in the U.S. market and dramatically lowered the price fishermen receive at the fish house.  Meanwhile, seafood chefs are attempting to get consumers to try out species they’ve previously overlooked (mainly because many of their former favorites are severely depleted), with dogfish sharks among the former “trash fish.”  While this movement gains momentum, fishing industry groups and 19 Senators and House Reps from coastal fishing states are exploring a different option, one that may put spiny dogfish in your local school lunch.

Should scientists avoid publishing shark migration data because it helps fishermen? Spoiler: No

Conservation, Science

In recent weeks, some conservation activists have been promoting an idea that I would like to respond to as a member of the scientific community. They claim that scientists shouldn’t publish data about shark migrations, movement, or population dynamics because such data helps fishermen to find areas where there are lots of sharks and kill … Read More “Should scientists avoid publishing shark migration data because it helps fishermen?

Was Aquaman quietly saving the world during Man of Steel?

Popular Culture

Man of Steel was a thoroughly entertaining superhero movie and a serviceable Superman movie. Fortunately, the last son of Krypton was not the only super-powered being saving the world, as the king of Atlantis was hanging out, cleaning up ol’ Kal-El’s mess.

It has been 98 days since our last Aquaman is Awesome post. We’re due.

Arthur Curry’s presence is first felt near the beginning, while a scruffy Clark is trying his best impression of Jack Kerouac auditioning for Deadliest Catch. Pre-Supes can’t help but hurl himself at a burning oil rig, rescue the roughnecks, and then keep derrick from collapsing on a hapless helicopter. Explosion. We cut to some Kansas flashbacks. Mr. Soupy floats in the water. Pan up and, inexplicably, there’s a couple of humpback whales just chilling, amidst the carnage of a collapsing oil rig,  having a casual sing-in. No doubt those whales are having a chat with a rogue Atlantean, swimming somewhere off screen. He’s probably making sure that the Caped Clam Chowder doesn’t ruin his handy work.

Because, obviously, Aquaman was the one who knocked out that oil rig. I said he was saving the world, not saving humanity. That’s Crab Bisque’s gig.

A citizen science project to monitor sevengill sharks in San Diego

MikeyMichael Bear is  Science Diving Editor for California Diver Magazine and  currently contributor to Marine Science Today with over a 1000 cold-water dives, an AAUS (American Academy of Underwater Sciences) Scientific Diver and  founder of Sevengill Shark Sightings.org. He  lives and work  in San Diego.

 

I am not a professional shark researcher–just an experienced San Diego diver who has been diving in the San Diego area since 2000. In October of 2008, I began hearing reports of encounters between local San Diego divers and Sevengill sharks, (Notorynchus cepedianus).   At the time, I thought this a bit unusual, since this was the first I had heard of these encounters in nearly a decade of regular diving in the San Diego area and monitoring local Internet dive boards. Between 2000 and 2006, almost no encounters were reported. But in 2008, that all changed and they began appearing on  the dive boards and  lists, one here, two there, five there,  slowing increasing until it was obvious that something was happening–exactly what was not clear–only that more and more encounters were being reported by divers.

Then, in the summer of 2009, I had my own memorable encounter with a Sevengill.   I was diving off of Point La Jolla when a large seven footer glided majestically between me and my dive buddy, who was no more than two meters away from me.   To say we were startled would be an understatement.   It was this incident, along with the increase in reports by other divers, caused me to set up a website  later that same year,  allowing San Diego divers to log and document their encounters with this species, as a sort of  personal citizen science project, because  no local marine institution, including Scripps Institution of Oceanography and NOAA SW Fisheries in La Jolla, had ever done any baseline studies locally prior to this point–I know, because we checked.

New “Exploration Science” program is open for applications, looks pretty freakin’ awesome.

The University of Miami has started a new Master of Professional Science program called “Exploration Science“. The program will teach students both the theory and skills behind field-based research, and graduates will be well equipped to lead field research expeditions in a variety of environments around the world. Classes include “Exploration Technology”, a course on … Read More “New “Exploration Science” program is open for applications, looks pretty freakin’ awesome.” »

OpenCTD first soak test

The Open CTD Project

Two weeks ago, we launched Oceanography for Everyone–The OpenCTD, a crowdfunding project to develop a low-cost, open-source CTD. After a few days hunting around for the best sealants, I put the prototype (name pending, suggestions welcome) through its first soak test. The results were… mixed. I left the CTD soaking for 12 hours (with hardware removed) … Read More “OpenCTD first soak test” »
