Imamura, Ken Tlingit Halibut Hooks Critical design and materials information regarding the Native halibut hook are in danger of being lost as the carvers and users pass on. Although the appearance of the hook is well-documented in literature, there appear to be no references regarding criteria affecting its evolution. This paper attempts to place the hook in context of available materials, cultural preferences, fishing practices, and fish behavior. It also provides the basis for accurate reproductions of hooks actually carved and used by halibut fishermen.
