Increasing Coded Wire Tag (CWT) submission rates
The CWT program relies on voluntary submissions of heads from adipose fin-clipped chinook and coho salmon to estimate the quantity and stock composition of salmon in various fisheries. Over the past several years, submission rates have decreased. Returns of heads from adipose clipped coho salmon have become so low that they no longer provide sufficiently precise CWT catch estimates for stock assessment purposes. In certain fisheries, recovery rates of heads from adipose clipped chinook salmon are also low.
Recreational catch taken on guided trips, both lodge-based and non-lodge based is one element of the recreational fishery that has seen increased head submission rates in recent years, due to cooperation of the guides in collecting and in some cases delivering heads. In 2013, the Department will strive to increase the proportion of guiding companies collecting heads to better represent their fishing activity. Where it is possible, head collections and logbook data will be combined to realize the full benefits of these programs.
To increase awareness of the CWT program and to increase the rate of salmon head submissions, the Department is increasing promotion of the CWT program through communications with the SFAB and Sport Fishing Institute. For further information on the CWT program, please see:

With an increase of WCVI Coho Salmon forecasted for 2013, it will be a good opportunity to increase head submissions when/here possible - understanding that fewer WCVI/Canadian Coho are clipped than US..
Thoughts?
