The Dickens You Say! (A brief history of the Atlantic Cod).



The scene: bedroom of Ebeneezer Scrooge, commercial fisherman, somewhere in New England, late in the evening.  The ghost of his former partner, Jacob Marley, appears through the wall.
Jacob: Ebeneezer, Ebeneezer, wake up!

Ebeneezer (groggily): Jacob, oh my goodness, is that really you?

Jacob: It is, indeed, Ebeneezer.  I come with a warning for you.

Ebeneezer: What is that you are all tied up in?

Jacob: Those are the fishing nets we used in life, Ebeneezer.

Ebeneezer: Looks darned uncomfortable.

Jacob: Trust me, it is, but that’s not the worst of it by far.  Not at all.  So that you can learn more, you will be visited by two ghosts tonight.

Ebeneezer: Two ghosts?  Sounds vaguely familiar.  Aren’t there supposed to be three?  Are you going cheap on me?  You always were a cheapskate, Jacob.

Jacob: When the clock strikes one, all will be revealed!  (He disappears into the mist).

Ebeneezer: What a crazy dream!  I knew I shouldn’t have had fish for dinner tonight!


Later that evening, the clock strikes one. The Ghost of Atlantic Cod Past. a large fish, enters the bedroom through the wall.

Ghost: Ebeneezer, wake up!

Ebeneezer:  (in terror) Oh, please, no, let me sleep.

Ghost: You have slept long enough.  Tonight, your eyes will be opened.  I am the Ghost of Atlantic Cod Past – take my fin and we will trawl for knowledge of your region’s past.

Ebeneezer: Rather ironic, I’m trawling with a fish, rather than for a fish.

Ebeneezer and the Ghost leave the bedroom and arrive in the port of Gloucester in 1800’s Colonial New England, overlooking the harbor.

Ghost: Did you know that fishing was our country’s first industry?  Hundreds and hundreds of those schooners you see operated out of several New England ports, catching cod with actual baited lines.  There was no refrigeration yet, so cod was “salted” at sea to preserve it.  Salt cod was then sold all over the world, and related industries like boat building also boomed.

Ebeneezer: Fascinating, if just a little primitive.

Ghost:  Primitive?  I’m guessing you never read “Captain’s Courageous” by Kipling?  You might change that description to adventurous if you had.

Ebeneezer:  Hmmm, never heard of it, can I get it on my Kindle?

Ghost: Not from here you can’t! You’d have to go to a library or a bookseller.  But it is time for us to move on.

Ebeneezer and the Ghost arrive in New Bedford, circa 1925.

Ebeneezer: Ooh, steam trawlers.  Now we are coming up to modern civilization, something almost recognizable.

Ghost: The Industrial Revolution completely changed the fishing industry.  Trawlers, cold storage, and distribution modernization allowed fresh fish to be shipped far away from ports.  Species other than cod, like haddock and herring, were then targeted.  The popularity and “harvesting” of fish soared.  When fisherman “fished out” one area, they just moved on to another.  Scientists warned, even then, that this growth couldn’t be sustained.

Ebeneezer: Oh, come on, a few guys on boats started using nets rather than fishing lines.  How much damage could they do?

Ghost: Dragging those heavy nets across the ocean bottom damages marine habitats.  And, let’s see, ah, in 1930 alone tens of millions of haddock were “harvested” around Boston, and even more millions of baby haddock were just discarded dead at sea!  Fishermen were using nets with too small a mesh.

Ebeneezer:  So, of course, they acted quickly to fix that process, right?

Ghost:  Oh, absolutely, yes, 23 years later, in 1953, the first regulations specifying a minimum size for trawler nets were enforced. 

Ebeneezer:  Hmmm, well, you know there was no internet in those days.  And you had to spin a dial on a phone several times to make a call.

Ghost:  Tough times for all concerned.  Particularly if you were a baby haddock.  But it is time for us to move on.

Ebeneezer and the Ghost arrive in Washington, D.C. in 1976.

Ebeneezer:  Hmmm, the U.S. Capitol, surely you aren’t going to tell me there’s a fishing frenzy going on here?  Or is it just time for the Friday Fish Fry in the Senate?

Ghost: No, this is where the Magnuson Act was passed, allowing the U.S. to control its ocean waters out to a distance of 200 miles from shore.  You see, profitability in the fishing industry had waxed and waned since the early 1930’s.  Stocks of various fish had dwindled, while the tastes of the American public changed frequently.  And a newer threat had arisen in the 1960’s: ocean-going fish factories, known as deep water fleets, were coming to Georges Bank from many other countries, all over the world.  These could do the work of a thousand of those old schooners and deliver consumer-ready fish in half the time.

Ebeneezer:  Well, that’s a good thing, right?  Protecting our shore from foreign interlopers?

Ghost:  Lots of people thought so at the time.  All the international fleets had to leave.  The government offered easy financing to build new, modern fishing vessels, mini versions of the factory deep water trawlers.  Unfortunately catch quotas were seen as standing in the way of this new, revitalized fleet and were abandoned.  By the early 1980’s, fish catches were again at record highs, higher than those recorded even during the time of the deep water fleets.  It just couldn’t last.

Ebeneezer:  Let’s see, we did just what the international deep water boats were doing, only more and better? There’s a saying, it’s all over except the finger pointing?

Ghost: Exactly.  One by one, the stock of cod, halibut, perch and flounder collapsed.  By supporting the fishing industry, the government was blamed for having contributed to the problem.  Environmental groups rallied to the cause, too late.  Even fishermen then clamored for more and reasonable regulations and fish quotas. 

Ebeneezer:  I suppose you could say there is a lesson in there somewhere for all of us.

Ghost:  Somewhere?  You have become a master of understatement, Ebeneezer!  I believe you have learned something tonight.

Ebeneezer: Ghost, I have seen enough to become seasick.  Please take me home!

Ghost: As you wish, my work is done.  But yours is not, you may expect another visitor soon.


Later that evening, the clock strikes two. The Ghost of Atlantic Cod Present. a much smaller fish, enters the bedroom through the wall.

Ghost: Ebeneezer!  I have come to enjoy your company tonight.  You have enjoyed the company of many of my brethren, haven’t you?

Ebeneezer: Bah, humbug!  Can you come back in the morning?  I really need my beauty sleep. Yikes, is this a dream or a nightmare?  You are not looking well, ghost.  Why so emaciated?

Ghost:  A lot of the small prey that I eat are gone.  Decades of overfishing really upset the balance of the ecosystem.  For a while the population of the fish that I eat exploded, but then their prey, the zooplankton, declined.  It’s a complicated world, you know.

Ebeneezer:  But surely you can just come back?  Fishing moratoriums have been in effect, on and off, for going on twenty years now. 

Ghost: Scientists aren’t completely sure.  There’s a lot of factors involved, probably more than we understand.  The population of seals that prey on me.  Nutrients and pollution in the ocean.  Global warming.  Ocean currents.  Your fishing moratoriums have helped, just in time for sure. We’ll see.  The last measurement of my population in Georges Bank was about 10% of a target goal.

Ebeneezer:  Well, that’s a relief. 

Ghost:  Swell.  I’ve assuaged your conscience, my work here is done.  You can safely keep eating your scrod.  Back to bottom-feeding for me!

Later that evening, the clock strikes three. The ghost of Jacob Marley returns to the bedroom through the wall.

Jacob: Ebeneezer, I’m back! You said you wanted a third ghost.

Ebeneezer: I’m tired, but I think I’d prefer the Ghost of Atlantic Cod Future, no offense to you.  To wrap it all up for me.

Jacob:  I couldn’t find any volunteer in that category, that population is distinctly lower than it once might have been.  Didn’t you learn anything tonight?

Ebeneezer:  Oh, come on, I had cod earlier this evening, how bad can it be?

Jacob:  Are you sure it was cod?  Restaurants are known for disguising their fish very well.  Have you ever eaten Chilean Sea Bass?

Ebeneezer:  Sure, many times.  I have a refined palate, you know, and it has a distinctive flavor.

Jacob:  Actually, what you ate was Patagonian toothfish.  Another fish that was threatened when it’s popularity exploded.  Those marketing people are quite good.

If you did have cod, it could have also been from Iceland or Norway, another reason fish is so expensive these days.  They are doing some good things there, though, fishing sustainably, some even using hook-and-line gear.

Ebeneezer: You’re kidding, talk about primitive!

Jacob: Sheesh, you are not making this easy.  I have two questions for you.  At its low point, the cod population in the ‘90s was about 4% of what it was in the Atlantic in 1850, 150 years ago, by our best measurements.  What do you think would happen if, because individual farmers wanted to make more money, 96% of all pigs, chickens and cows were killed off?

Ebeneezer:  Outrage.  Protests.  Marches on…somewhere.  Internet tweets exploding.

Jacob:  Well, yes, I will give you the latter, at least.  But the outrage over cod and other ground fish washed away in a sea of coulda, woulda, shoulda pretty quickly into hopelessness and apathy.  And we’d had decades to see it coming.

Okay, question number two.  How much of that initial outrage would be spurred by our thoughts of not being able to eat the dinner we like, or not being able to earn the income we are used to, and how much by the thought that we practically committed complete genocide on another Earthly, living species?   What does that say about humanity?

Ebeneezer: (Gulp).  You know, Jacob, I could use your advice.  I’ve been thinking of getting out of the fishing business for a while now.  The fun is long gone, what with all these crazy regulations.  Fishing, what a bore, let’s face it.

I need something more adventurous, something exciting.  You say those marketing people are doing great work, thinking up ways to sell stuff to people who need it?  Maybe I’ll give it a try.

Jacob: Sheesh, only in America!

The Final Frontier?




Q: The skeleton of what exotic, aquatic animal is displayed in many American homes?

A: Me!  I’m a coral.  Lots of you have samples of my skeletons in your home aquariums. That’s kind of spooky, if you ask me. You people call yourselves civilized?

You’ve heard of coral reefs?  They are made by us corals. That’s right, we are very tiny animals, called polyps. We have cell membranes, are just a few centimeters in length, and a few millimeters in diameter.  I’m spineless, yes, and genetically equivalent to my many brothers and sisters.  We are a little like an underwater “Borg” colony, I guess you could say.  A sack with a stomach and a mouth, with surrounding tentacles that can catch plankton.  We keep it simple, although there are a thousand different kinds of us, producing different exoskeletons that might end up looking like a brain or a table top.

Single-cell algae live right within my tissues, providing me with energy and nutrients and color via photosynthesis.  How cool is that?  Hey, I protect them and they work for me.  Sunlight is the key for that process to work so I need to live in clear water, not too deep and not too shallow.  I secrete a hard, carbonate exoskeleton which protects me.

Those skeletons of me and my family add up and bond together over time to form coral reefs.  Persistence is the key to that, us corals have been around in one form or another for over 500 million years. Yep, pretty much forever. 

Most of our existing work has been around for less than 10,000 years, though, that is when melting ice caused sea levels to rise and flood continental shelves.  My kind had to grow upwards, matching the rising sea levels.  Persistence does pay off, as you can see some of our reefs from space today.  How much of your work can be seen from space?  Nothing I know of besides the Great Wall of China (I heard that has been crumbling, by the way, somebody had better get on it!)

So what good are coral reefs?  Well, we provide homes for about 25% of all marine species, even though we cover only about 0.1% of the world’s ocean surface.  Coral reefs are like English muffins, we have the nooks and crannies that fish love to navigate, or love to visit to eat those fish.  That  also creates a lot of touristy opportunities for your kind.  My reefs have been called rainforests of the sea, because of the extremely diverse ecosystems which you can find there. 

Actually, I would really prefer that you did NOT find them there.  Human interference is one thing that is killing me off.  Prime example: sunscreen.  You heard right!  Thousands of tons of it washes off of humans and finds its way into ocean environments.  Some sunscreens use chemicals which, if even a minute part of them gets into me, it stimulates viruses inside my algae. The viruses replicate until the algae explodes.  Without the algae, I turn white and die.  This can end up infecting the whole reef, a phenomenon known as coral bleaching.

Do you need any more evidence that we’re all interconnected on this Earth?  Seriously, I would reconsider/review your choice of sunscreens.  These four chemicals that cause my viruses (oxybenzone, butylparaben, octinoxate, and methylbenzylidene camphor) are ones that you may be PUTTING DIRECTLY ONTO YOUR BODY.  I’m no doctor or scientist, I’m just saying, let the buyer beware.  Smart companies are now marketing sunscreens that don’t include them.  Thank you!

Ironically, I know quite a bit about sunscreen.  My symbiotic algae make a compound they share with me, which I modify as a sunscreen that protects both of us.  It really works, fish that feed on coral even benefit from the same protection.  Smart scientists are trying to replicate a synthetic version, in the hopes of creating a pill for humans.  Since coral is endangered, they at least have the decency not to try to extract it from us.  That would pretty much be the final indignity.

What with global warming, acid rain, overfishing, agricultural runoff and pollution, I have my tentacles full.  About 25% of coral reefs have perished over just the last few decades.  Another 25% could easily die out over the next twenty years if things don’t change.  Seems like you humans are racing to see which you can destroy first, the rainforests on land or the “forests” under the water. That would be one-half of all coral reefs – gone.  Where’s the outrage?  I need a new publicist, that’s for sure.   

Well I’ve spoken my peace, for what it’s worth.  Now for the entertainment part of our show.  I’ve always wanted to paraphrase the great and wise Seabastian, with apologies to the Disney folks.  Feel free to sing along, it will make you feel better!  I think you know the tune.

Under the sea
Under the sea
Coral be living
So don’t be giving
Your sunscreen to me

Under the sea
Under the sea
You got to hear it
Just don’t go near it
Naturally

Under the sea
Under the sea
Darling it’s better
Down where it’s wetter
Please take care of me.
