The sanma (Pacific saury) that's caught at this time of year is rich with heart-healthy oils, and is considered a quintessential autumn delicacy in Japan.
But unlike other fall delicacies such as matsutake mushrooms, sanma has traditionally been considered affordable. This national favorite is in crisis, however, and seems to be following the pattern of other popular fish like bluefin tuna and eel.
