Production of herring and mackerel is in full swing at HB Grandi’s pelagic complex at Vopnafjördur.

“All of the herring goes for frozen butterfly fillet production. As for the mackerel, the smaller grades have been headed and eviscerated, while the larger sizes have gone straight to the blast freezers,” Magnús Róbertsson said.

A tiny proportion of whole fish has been sent to fishmeal production, although all of the waste and offcuts are processed into meal.
