Big Trouble in Little Bering Sea

Oh man, you guys. This is a doozy.

I posted a brief Tanner crab (Chionoecetes bairdi) update from Alaska Department of Fish and Game yesterday on Facebook. TL;DR - the Bering Sea fishery for bairdis is closed for the 2016/2017 season.

The bairdi fishery in the Bering Sea has had a rocky past with openings and closures fluctuating throughout the years, but it was starting to look good again even as recently as 2015! The fishery was closed from 1997 - 2004, open fully 2006 - 2009, closed again from 2010 - 2013, then open fully until 2015 with high catches and high vessel participation (112 vessels in the 2015/2016 season compared to 32 in 2013/2014).

You can read all about the fishery in the latest Bering Sea/Aleutian Islands stock assessment and fishery management report (in nerd lingo - the crab SAFE), which is put out by the North Pacific Fishery Management Council. Here's a link to the Crab Plan Team with all their fun reports, and this link will send you to the current Council meeting (happening now) where you can find the 2016 crab SAFE in the Agenda. It's listed under "C. Major Issues/Final Action Items" as the first item.

OK, so that's bairdi, but you all know I really love me some opies. How are they doing?

Not good. ADF&G announced that Bering Sea snow crab will be open this year (October 15th, as usual) but with the lowest total allowable catch (TAC) in 45 years. The low TAC, at 21.57 million pounds, is  nearly HALF of what it was last year (40.57 million pounds)! Why? Because surveys of the crabs have shown a decline in the number of mature males out there (who we like to eat) AND mature females out there (who make the babies).

This low baby-makin' biomass means potentially fewer adults in the future. That's why management has to be so conservative to allow for the crabs to do their business and replenish the stock. But for the moment it also means low catches and A LOT less money for our crab fishermen, processors, and on down the line. The other thing fishermen have to worry about is any accidental retention of bairdis since that fishery is closed, making these crab-cousins prohibited.

Good luck, crabs!

Shrimp Publication!

Remember WAY back in the day when I shared these photos of shrimp embryos?

spot shrimp and coonstripe shrimp embryos

I was processing shrimp collected from different sites around Port Valdez for hydrocarbon analysis. Polynuclear aromatic hydrocarbons (PAHs) are simply compounds made up of hydrogen and carbon that occur in crude oil. They = not so good for human consumption, or for animals, or for nature in general (see the Exxon Valdex Oil Spill). So this project looked at whether or not shrimp collected near oil tanker operations were safe to eat. My role was properly dissecting the shrimp and separating them by body part - tails (the most-often eaten item), heads (sucked on - not my style), and eggs (oy, I'll get to this one). And now the results have been published! Woo!

Let's cut to the chase: the majority of everything was safe with the small exception of eggs! ... And here's where I get on my soapbox: we shouldn't be harvesting reproductive females in any fishery that we hope can be sustainable. The lobstermen on the East Coast know this and v-notch the tails of reproductive female lobsters before returning them so that (a) they have a chance to hatch those delicious babies and (b) even when they're not gravid (showing eggs on the underside of their tails), it's known that these gals can get the job done for future years of successful harvests. Long story short - you shouldn't be eating the potentially tainted shrimp eggs from Port Valdez anyway! (Honestly, most shrimp you buy in general are terrible [high bycatch in trawl shrimping, pollution from farmed shrimp, slavery in shrimp processing, etc.] so unless you or your friend are catching shrimp using pots, you should just avoid 'em.)

(Disclaimer: that's just my opinion, well thought out though it may be, and doesn't reflect the opinion of any organization for which I've done research.)

Lobster rolls are a waste of time, money, and lobsters

I've said it before and I'll say it again: lobster rolls are a waste of stomach space. Why spend money on lobster that's drowned in mayonnaise and miscellaneous spices and thrown on a bun when you could have fresh boiled lobster with liquid gold aka melted butter? Isn't the point of eating lobster to enjoy the taste of lobster? If you want mayo on a bun there are so many better things to eat: BLTs for example! (PS, I feel the same way about lobster macaroni and cheese. Just, no.)

Where is this rant coming from? Recently different groups have been cracking down on seafood fraud - the mislabeling of food as higher quality products. For example, an Oceana study found that 43% of salmon sold in restaurants and grocery stores from places like New York and Chicago were mislabeled, and the most common wrongful ID was calling farmed salmon "wild-caught". That's a HUGE no-no for this wild-caught Alaskan salmon-loving gal!

Where lobster rolls come in is that another study by Inside Edition showed that many restaurants selling lobster rolls, lobster ravioli, and other heavily-processed lobster dishes are actually serving cheap lobster substitutes like "langostino" (aka squat lobsters, which you may know are more closely related to crabs than true lobsters). Less egregious but equally shady is serving actual lobster cut with other things like whiting, a common name for several white-meat fish like pollock or hake.

In the investigation, one third of the tested "lobster" meat was mislabelled! And the thing is, most people probably couldn't tell because their "lobster" was smothered in mayo! So I don't feel too bad for people who were bamboozled, but I think it's wrong nonetheless. An interesting point that was raised during this investigation is that one restaurateur said they did nothing wrong with mixing fish in to their lobster roll: (A) some people just use a frozen pre-mixed melange of seafood, of which lobster makes up an unknown percentage, for their lobster rolls, and (B) mixing lobster with things like surimi (that fake crab meat made from ground up pollock) and selling it as "lobster salad" should just imply to you, the costumer, that you're getting more than what you're paying for (and by "more" I mean "less"). And I'm not really knocking surimi - I like California rolls as much as the next person, and I was an observer in a fish processing plant that made surimi, so I've seen it from start to finish!

Mmmm, I can still smell the ground pollock from here!

Anyway, do yourself a favor: next time you want lobster, just order the whole thing with a side of garlic butter, put on a bib, and enjoy pure crustaceany goodness!

this is how you do it! (shananana-na-nana)
