Unfortunately i don't have the qualifications you listed ,however i have emailed the DFO several times asking how the system works and why they have closed the tidal Fraser to sport fishing , No answer to me emails , In my opinion the system is broken and needs to be changed . Do i have all answers on how to fix it No i do not , But I do believe that if the river is closed it should be closed for all user groups , if it is open then it is open for all user groups ,i find it very frustrating that some groups can fish for salmon when we cant as sport fishing is the lowest impact to sockeye in the tidal Fraser
Just to add I have been fishing the Lower Fraser all year for Sturgeon when i have not been up at the lakes in Kamloops , Last night was beautiful out on the Fraser between Golden Ears Bridge and mission , It was nice to see the amount of salmon boiling and jumping in that part of river as its the most i have seen all summer
Cheers
