6.1. Catch Monitoring and Reporting
Initiatives
The development of an improved catch
monitoring regime will continue to be a priority in the management of
recreational fisheries. The Department is working with the Sport Fishing
Advisory Board to develop catch monitoring standards for the
recreational fishery. The standards focus on data collected to estimate
catches, releases, and essential biological data for stock assessments
and fishery management evaluations.
6.1.1. Initiatives to increase Coded
Wire Tag (CWT) submission rates
The CWT system relies on
voluntary submissions of heads from adipose fin clipped
chinook and
coho salmon to estimate the quantity and composition of CWTs caught by
anglers. Over the past several years, submission
rates have decreased for both species, but most drastically for
coho salmon. Now recovery rates
for coho salmon have become too
low to provide sufficiently precise CWT catch estimates for stock
assessment purposes; in certain fisheries, recovery rates of
chinook salmon are also too low. Further,
the 2005 expert panel review of the CWT system found that an increased
proportion of the total catch was occurring in sport fisheries, which
are more difficult to sample than commercial fisheries. To increase
angler awareness of the program and head submission rates, the
department is increasing promotion and advertising efforts, and
communicating these concerns to the Sport Fish Advisory Board. In 2009,
the Department will explore additional means of improving the certainty
of the recreational fishery CWT data.
Sport catch taken on guided trips,
both lodge-based and non-lodge based, is one sector of the sport 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 2009, the department will strive to increase the proportion of
guiding companies collecting heads to better represent their fishing
activity.
