In the evaluation of the trap they need to look closely at the economics, especially how many participants are needed to install/operate. We have GN and troll, which are single operator and maybe one crew. Reef nest take a couple of folks to operate and purse seines are more crew-intensive. My point is that both state and tribal GN use the one-man one operation model with the idea that one hard-working person can "make it". I know some opposition to selective fishing with beach seines and such is the requirement for more people. On a declining resource, sharing income may not work.
I would supect that implementation, if it works, will have to closely look at replacing the GN with an option that is economically more viable in addition to being ecologically more viable.
Probably also need to look at release of other species (sturgeon) and how pinnipeds react/interact.
