Femfisher I don't know what practice is allowed by the tribal fisheries but call Noaa and ask for Mark( I think, not sure of the last name) he is a poaching officer for the pacific northwest and he might be able to help you but he will most likely refer you do the tribal fisheries and you will get the run around. Noaa does have right to step in and override when activity in progress does cause harm or is illegal. But they to have to follow certain guide lines set forth by the tribal fisheries. They can only investigate and arrest if the rules being broken are illegal under the tribal fisheries. There are so many provisions on what one can and can not do it is hard for most of the lay person to deciefer what is leagal and what is not and to contact the proper authorities.
