PSA: Tilapia /= Catfish
Sunday, January 6th, 2008Last month I was sitting around in the TA office and someone commented, scornfully, that “tilapia” was just a fancy name to make the stupid bourgeois eat catfish. Having been raised relatively bourgeois, I blinked and did not mention that I had never heard that tilapia was catfish. It did actually make a fair amount of sense. Who among us had heard about tilapia, say, six years ago? Not bad evidence of some kind of clever marketing ploy, I thought.
I was so convinced that I even attempted to pass it on to a carful of people on our way to the Victoria’s Secret semi-annual sale over at West Towne Mall,* although I did admit that I didn’t have independent confirmation.
Keely was a little skeptical, although she allowed that she hadn’t heard of tilapia before she moved to Madison, but argued that since she didn’t eat fish before then, why would she have noticed? Other passengers, however, confirmed that they, too, had only become aware of tilapia in the past few years.
So when I got home, I looked it up online and discovered: tilapia and catfish are about as distantly related as it is possible to be and both be FISH. Wikipedia informed me that tilapia are of the family “Cichlidae” while catfish are classified into about 50 freaking different families,** NONE of which are “Cichlidae.” According to the Wikipedia catfish entry–which, sure, take with a grain of salt–5% of vertebrate species are catfish. AND YET. Tilapia? Not catfish.
Being motivated to correct the misconception I had inadvertently been spreading, I brought it up when I called home in the evening, which set Dad off, and led to his confirmation–he, too, turned immediately to Wikipedia–that catfish and tilapia are, as noted, as totally dissimilar as two fish can be. I don’t know if “not tasting like much of anything” would be considered a phenotypical similarity or not; as my friend Crystal says, people fry catfish because they like the taste of fry and the catfish are handy.
By “set Dad off,” I mean that we are both compulsive reference checkers. I may or may not have previously related the story of an argument I got into with some of the girls in my 8th grade gym class, the subject of which I have long forgotten although some corner of my mind is convinced it had something to do with gypsies–I could totally be making that up–and so I went home and looked it up that night and came back in, the next day, vindicated, and told them loftily that I was, in fact, totally right and backed up by encyclopedic sources.
For some reason no one was at all impressed, and I was probably lucky to escape the interaction without being stuffed into a locker. It turns out that citations are not pertinent to junior high debate. So now you know why I’m in graduate school.***
Dad, anyway, had apparently known about tilapia since the early 80s, when they were the hot new thing at the University of Arizona’s School of Agriculture. They can be raised in very densely populated tanks, or, for that matter, in irrigation canals. The internet also tells me that they only require 1.2 pounds of feed to put on one pound of flesh, which compared to 6-8 pounds of feed for one pound of cattle flesh is pretty damn good. Plus, you know, they taste like whatever sauce you put on them.
And goddamn are they cheap. I picked up a bunch of frozen fish at Trader Joe’s this week as part of my effort to get back into shape, and you can get over a pound of tilapia for $4. That’s at least three meals right there. If I had a drainage ditch I could cut out the middleman… but I think I’m willing to pay for Trader Joe’s to handle it. Now the real question: what do I put on it when I bake it for dinner tonight?

*The sale started three days ago so it’s probably hopelessly picked over by now, plus any time you enter the VS store you’ll be surrounded by 12-year-olds, but the sale seems to bring out the especially inappropriate, e.g. the woman who was dragging her approx. 8-year-old daughter from bin to bin screaming, “Let’s look for some EXTRA SMALLS for you!” I mostly try not to judge other people’s parenting and god knows I am no arbiter of What Is Appropriate, but sweet fancy Moses, someone is going to be telling a therapist about this someday.
**To be totally accurate, 36–unless my finger slipped while I was counting down the list.
***Also, of course, a number of my family members went to graduate school. I don’t know if my father’s father was a compulsive reference checker or not, but it wouldn’t be a huge surprise.
