• Sushi: the Global Catch
  • Tuna farm

The Chicago Food Film Festival isn’t the only food-film game in town this weekend.

Thanks to the planet’s insatiable appetite for sushi, the global supply of bluefin tuna has been depleted by as much as 80 percent since the 1950s. The bluefin is an apex predator—that is, a predator that as an adult has no natural predators in its ecosystem—so when it’s gone, the fish it eats will decimate the species they eat until the oceans are empty of everything but invertebrates. This perilous situation provides the unifying thread for the 2011 documentary Sushi: The Global Catch, which wanders from sushi’s origins as an occasional meal to its ignoble status as a convenience food that threatens the existence of life in the world’s waters. Unlike the recent Jiro Dreams of Sushi, it doesn’t inspire conflicting feelings of guilt and hunger—it’s nearly devoid of fish fetishism (the makimono served in a Polish restaurant looks downright manky). Director Mark Hall also ends on a hopeful note, profiling restaurateurs that serve only sustainable species and an Australian tycoon who may have figured out how to breed bluefin in captivity. 75 min. It starts tomorrow at the Film Center. Click here for showtimes.
