This is a proposal for research into using freeze-branding or laser branding to mark crustaceans. "The need for a method of marking crabs, shrimp, and lobsters for fisheries research and management is well documented. The marking techniques currently available are not wholely satisfactory. A good marking technique should produce an identifiable mark that will remain throughout the life of the animal, will not interfere with the act of molting, will not cause a differential mortality in marked animals by increasing susceptability to predation or disease, is inexpensive and adaptable to field procedures, and is easily recovered or recognized in commercial. or sport harvests." (from the Introduction) Includes black-and-white photographs of marked Dungeness crabs.
