Pollock (or pollack) is found in abundance in both Atlantic and Pacific waters. A firm, flaky white-fleshed fish, it is much more sustainable alternative to cod. Pollock move in large shoals near the surface of the water and can easily be caught by mid-water trawling methods which leave the sea bed untouched.

 

Pollock are generally available only from May to September, but freeze exceptionally well, so buying from frozen is also a good option.
