Alaska pollock producers are transitioning from surimi to block production due to the influx of cheap surimi from Russia in global markets, including Japan. This shift is driven by the growing popularity of deepskin, a cut that removes the pinbone and fat line, among key customers in the seafood industry such as McDonald's. While US pinbone-out pollock fillet block prices are under $4,000 per metric ton, deepskin blocks command higher prices.
