Do You Like Frozen Fish??? The catch arriving at market in Boston are frozen before they hit the (processing) packing plant. While you are turning up the heat, fishermen off the grand banks fight winter storms that coat their ships with tons of ice. An ice covered ship pulls into port. Crew members use sledge hammers to break up ice chunks off the ship before they can unload their catch. Men unload fish, bucket raised from below deck is hoisted across to dock and dumped.
