We’re having some guests over for dinner tomorrow night, and cooking fish.
So naturally we turned to The
Ethical Gourmet for advice on which fish are politically correct. And found
this, on skate:
Slow to mature and reproducing in very small numbers, skate are an overlooked
problem… The fish are sometimes used to produce fishmeal for aquaculture
operations, but growing demand for them from upscale restaurants is also taking
Let’s say that aquaculture operations pick the cheapest fish to use for fishmeal,
and that our aim is to kill the smallest number of skate, thereby giving them
the opportunity to mature and reproduce. Should we eat skate, or not?
If we do, we’re obviously increasing demand for the fish, not to mention eating
dead skate ourselves. On the other hand, if we don’t eat skate, we’re decreasing
demand for the fish, which means that the price will go down, which means that
skate will become more attractive to aquaculture operations, and potentially
even more of them will be killed.
Is it possible that increased demand for skate from restaurants and consumers
could bring the price of the fish up to a level where it’s no longer economical
to use them for fishmeal — thereby reducing the number of skate killed each
year? Is this a case of "multiple equilibria," or something along
those lines? Or am I just desperately trying to rationalize the eating of a
delicious fish which has long been one of my favorites?
