Our Mackerel are caught by local fishermen in the Gulf of Maine. Once caught, they are harvested via the Japanese method of Ike Jime (活け締め). This technique is regarded as one of the most humane ways of harvesting fish. 

The Ike Jime Technique

Ike Jime takes a lot of extra time for the fishermen, but the technique yields are a far superior product and is much more humane for the fish. During the Ike Jime process, the fish are immediately spiked, which instantly kills them - limiting the suffering of the fish.

The difference in quality between a fish that has been Ike Jimed and one that has not been is vast. When a fish is not spiked, it produces lactic acid and ammonia, which naturally negatively impact the flavor. Ike Jime also helps remove the blood from the meat of the fish, helping to produce a much more flavorful fillet with a far greater shelf-life. 


Our mackerel are flash-frozen and Cryovaced. There are 2 head-on fish in a bag. The fish weighs approx 1.5 lb together.
