There are 2 DNA data collection projects underway. The Ardent Angler Program is one, and an excellent way for concerned anglers to help collect the DNA samples and catch log data. The SFAB has fully supported this program. The other is a DNA sampling program on WCVI being run voluntarily by some guides who are participating through the WCFGA.
Sadly, not enough participation frankly, which is placing the rec fishery under increasing scrutiny in fisheries such as SVI and WCVI when we negotiate international treaties and address conservation issues raised by other fishing communities. DFO needs more rec anglers and guides to step up and participate in the sampling program.
Bottom line, we need data to resolve issues such as this one or risk an ultra conservative decision process due to lack of solid data to support different decision outcomes in future.
As for seals taking fish from the test nets, I have personally observed the test fishery and not seen seals working the nets - I suspect mainly because the net is set and worked by the crew so the seals won't get a lot of opportunity to work the nets. Maybe it was just the day I happened to be observing, but there were not a lot of seals either, so my experience may not be typical of the spring chinook situation.
