Traps are made from wood stakes, piled stones and combinations of wood and stone materials. Their appearance in estuarine contexts dates to approximately 3500BP and use of the structures continued into the 20th century. This paper will explore the type of forms, their harvesting logic, their locations (vis a vis streams and estuaries), the relative numbers of different types, and their temporal occurrence as they relate to time period, salmon species, efficiency, sustainability and macroenvironmental change. It will be suggested that 'tidal pulse fishing', a type of estuarine salmon capture on ebb tides, exploded as a form of practice around 1000BP in response to intensified use of smaller salmon streams that support primarily runs of pink and dog salmon. A consideration of factors possibly implicated in this change will be presented.</style></abstract></record></records></xml>
