Processors are responsible for sorting, heading, bleeding, cutting, and packaging all fish products. Processed fish is sorted by size, frozen in pans, removed from the pans and packaged in frozen blocks using either fiber bags or boxes. Frozen cases are labeled and stacked in the freezer hold. Processors are also responsible for backloading bait and other supplies at the beginning of the trip and offloading frozen fish products at trip end. Working conditions aboard the vessel can be wet and cold.
