Abstract or Summary
  • The Dungeness crab fishery is the largest and oldest known shellfish fishery of the North Pacific coast of North America. The stability and development of this fishery is seriously hampered by increasing meat extraction costs and labor shortages. Alternative solutions to offset the increasing costs and labor shortages include: 1) development of an automated picking process or machine, or 2) identification or development of techniques to simplify and improve manual meat extraction. Because of the complexity of meat extraction, mechanization does not seem likely for some years. The second alternative can immediately help relieve the fisheries' problem. This paper has concentrated on the design and evaluation of improved crab meat extraction methods, in terms of skill, time and cost. The design of the improved method of meat extraction was in terms of the indirect skill factors (the individual, and plan and control), and the direct skill factors (materiel, necessity of motion, rhythm, and speed). This method's improvement study upgraded the skill level of crab pickers in terms of the six skill factors, and, in turn, reduced meat extraction time and lowered the overall picking cost to the processor. An overall plant meat extraction rate increase of 20 percent was realized by several fisheries, along with increases in meat yield. A training program, along with a motion picture training film and a pictorial instruction manual, was developed to implement the improved method of meat extraction.
