Mackerel Icefish: Right. It is starting to get a bit cold around the countryside so I thought this may be of interest.

It is a fish found only in the Southern Ocean and are mainly Heard and McDonald Islands, and islands in the south Atlantic such as South Georgia.

They are found in depths up to 700m with older juveniles and adults forming large schools at or near the sea bottom or mid-water range of the water column, feeding on krill and small fish.

They grow quite quickly and mature at a length of  between 22cm to 26cm after about three or four years. They grown to about 35cm.

Apparently the flesh is white and firm like the King George Whiting but with a higher oil content. They are good for grilling, baking or steaming.
