The untold story of Alaska pollock

This is a book cover redesign for a book called “billion dollar fish“. I chose to illustrate this particular book because it’s current Amazon sales rank #1,004,963. I think it’s an important story and one that needs to be told.
Here’s an extract from a paper entitled: “An empty donut hole: the great collapse of a North American fishery”
In 2007, the biomass estimate was at its nadir of 309 thousand tons, a decline of 98% from the maximum. In fact, in that year, during a test fishery conducted under the auspices of the Bering Treaty, a pair of Korean trawlers spent 2 weeks trawling for pollock in the Aleutian Basin, and caught just two pollock. Most fish in the catches were smooth lumpsuckers (Aptocyclus ventricosus) (CBS Treaty 2007). Now, after 20 years, the population still has not recovered. Bycatch of pollock in Japanese survey longline catches in the Aleutian Basin tend to support the scenario depicted above; there was a substantial but lower background level of abundance in the 1970s, which increased in the 1980s, collapsed in the 1990s, and now hovers around zero (CBS 2010).

ABSTRACT. Walleye pollock (Theragra chalcogramma) is North America’s most abundant and lucrative natural fishery, and
is the world’s largest fishery for human food. The little-known demise of the “Donut Hole” stock of pollock in the Aleutian
Basin of the central Bering Sea during the 1980s is the most spectacular fishery collapse in North American history, dwarfing
the famous crashes of the northern cod and Pacific sardine (Sardinops sagax). This collapse has received scant recognition and
became evident only in 1993 when fishing was banned by an international moratorium; nearly 20 years later it has not recovered.
The history of fishing in the North Pacific Ocean after World War II offers some insights into how the Donut Hole pollock
fishery developed, and the societal and economic pressures behind it that so influenced the stock’s fate. Overfishing was, without
a doubt, the greatest contributor to the collapse of the Aleutian Basin pollock fishery, but a lack of knowledge about population
biocomplexity added to the confusion of how to best manage the harvest. Unfortunately, the big scientific questions regarding
the relationship of Donut Hole fish to other stocks are still unanswered.
It takes a lot of time to make a drawing like that, so that’s it from me today!

A million people on Mars by 2060?
Really? Why? Aren’t there enogh bloody people in existence already?
I like Elon Musk. I really do. But I think his whole mission to mars is totally misguided. I think the best way to invest in humanity’s future is… by creating longer-lasting protection for the last remaining wilderness areas. If that is what leading biologists say we should do, then that is what we should be doing!
I think he’d be better off buying up a huge chunk of forest somewhere and just… leaving it intact. No human intervention. Or, if he must ‘build’ a structure, design a bloody great hermetically sealed dome over the top of the canopy, and just lock people in there for five or more years. It’d be cheaper, better for this planet.
How many emissions do those rockets make? How many emissions do making the rocket parts make? It’s just totally a waste of time buggerising about terraforming mars when we already have a terraformed planet here with millions of more naturally occurring species on it.
Technology got us here in the first place, it won’t save us now. The only thing that can save us now is … not clearing any more new land, increasing the size of existing wilderness areas. And planting lots and lots of trees all trhoughout suburbia.

Wow. Just, wow.
