All fishing vessels operating in the coastal pelagic species fishery, including catcher/processors, at-sea processors, and vessels that harvest in Washington, Oregon, or California and land catch in another area, may be required to accommodate NMFS- certified observers aboard to collect scientific data. An observer program will be considered only for circumstances where other data collection methods are deemed insufficient for management of the fishery. Any observer program will be implemented in accordance with § 660.517 .
