Why Don't We Open Additional Chinook Selective Fisheries in 2004?
The Department has received
numerous suggestions and requests that it expand selective fisheries opportunities
for marked, hatchery chinook in a number of areas. We are very supportive
of these ideas but also have certain key constraints that preclude us
from proposing additional chinook selective fisheries in 2004. We have
tried to summarize those constraints below.
In developing our mass marking and selective fisheries programs for coho
and chinook, WDFW has had to address questions about how the programs
might affect current management applications of the coded-wire tag (CWT)
system. As many are aware, the CWT provides the current foundation for
estimating fishery exploitation rates for chinook and coho stocks in coastwide
fisheries. As a result, the CWT has become key in implementing international
agreements under the U.S.-Canada Pacific Salmon Treaty as well as obligations
under the Endangered Species Act. In both cases conservation objectives
require that we measure fishery impacts on key stocks. While selective
fisheries can be an excellent tool to minimize impacts on wild stocks
and target fisheries on hatchery fish, they also can complicate the analyses
necessary to utilize CWT data. So as proponents for selective fisheries,
the Department has had the primary responsibility to evaluate these complications
and develop approaches that ensure that the CWT system will not be significantly
impaired.
These evaluations and assurances have been much simpler for coho than
chinook because of their life history differences (e.g., coho maturing
primarily as three year olds and chinook maturing at age 3, 4 and 5).
But in 2003 WDFW was able to reach a major milestone in this work and
implement the first selective fishery in marine waters (July, Strait of
Juan de Fuca) for marked chinook salmon with the intent to evaluate it
as a two-year pilot. At the same time other managers expressed significant
concerns with this fishery regarding the issues noted above, which the
Department had to address. In order to help meet those concerns, WDFW
agreed that it would not expand chinook selective fisheries for 2004 fisheries
(5/1/04-4/30/05) in order for us to consider results of the Strait's selective
chinook fishery evaluation. While there could be some exception to this
constraint, by agreement, such exceptions would only be possible for freshwater
areas where CWT issues are greatly diminished.
During the next several months, the Department intends to create a draft
list of additional selective chinook fishery ideas that it might consider
proposing for the 2005 season (e.g., 5/1/05-4/30/06) or beyond. Advanced
planning is required by agreements under the Pacific Salmon Treaty process
so that CWT issues can be appropriately evaluated. So the specific ideas
that we receive through our 2004 North of Falcon planning process will
be very helpful in deciding what times and areas might be most logical
for considered expansion of selective fishery opportunities in the future.
More information about this future planning will be available by this
summer.
The Department certainly supports the concept of expanded selective chinook
fishing to better meet our conservation and fishing opportunity goals.
Unfortunately, it has taken considerable time to address the implementation
challenges described above, particularly in marine waters. These fisheries
will continue to be a very high priority for the Department.
