This is Science Weekend. Any thing you read here should be interpreted within the context of picnics, cartoons, and sushi dinners. The last five days of Science Week featured stories from colleagues contemplating important stuff like sea cucumbers, sediment transport, and blue smokers. It went well. It’s good to have new writers. We need more.
To be honest, the “Science Week” challenge caught me off guard. Deep Sea News always writes about science. We never drag on about ourselves. Craig and I are invertebrate biologists interested in the physical and evolutionary processes that maintain deep-sea biodiversity. It’s like saying “Let’s have Overdrive Week,” at Hot Rod Magazine. We barely have time to consider anything but sea spiders, squids, giant isopods, and bubblegum corals. Still, that won’t stop either us from telling you about deep-sea fish.
Deep-sea cod (family Gadidae) are “one of the most important families of fishes in the deep-sea”. Their deep siblings include pollock and hake. Pollock is used to make fake crab legs in the Subway seafood salad. It’s packaged as a strange white Asian boloney caled sarimi. Sarimi fishermen catch pollock with bottom trawls off Alaska, and press the meat into a white pressed sausage stained with bright colors in the sliced meat section at the Vietnamese grocery. Check it out sometime.
Cod fish have been getting a lot of attention in the media because they supposedly harbor the source of a new cure for cancer. This diagnosis is a reprieve, in a way. Cod fish also dominate the global fisheries statistics, accounting for somewhere near 90% of the global fisheries catch. They’re obviously delicious. It’s like a crime. Hear the death bells toll.
Cod already suffered commercial extinction in the North Atlantic, for example. There’s a book about it (called “Cod”) showing that historical abundance of cod explains early European migrations, and these migrations are closely tied to cod’s demise. Apparently, there is an inverse relationship in marine fisheries between tastiness and survivorship.
Unfortunately, science won’t stop people from driving these species to extinction. Culture might, though. I’ve heard the most recent large scale recovery of groundfish stocks (like cod) occurred in the North Pacific during World War II, when war stemmed the decline of some fish populations because fisheries were restricted. It is ironic that the best chance for cod fish to survive is if they yield the cure for cancer, or a war breaks out.
