Perhaps there is a cause/effect relationship, with the exception of the Cowichan. Some evidence there that the habitat improvement effort is paying large dividends.
Hatcheries alone are not a good option IMO. We need a very balanced approach that includes hatcheries, sea pens, habitat and water quality. Also need some very selective pinniped control, and in some locations even predator control for certain bird predators. All stuff that needs to be done, and I'm sure we will have the usual suspects fighting all the above because it helps them sell memberships to feed the machine.
I'm also concerned that if we place all our eggs into one basket, and that fails, then we have real problems. For example, I'm seeing a lot of 3 year old fish now. More than we normally get. Either that is a good sign of things to come....or is it bad. One of the knocks on the S-1 program is that it produces an extraordinarily high proportion of 3 year old fish. That is potentially bad because it promotes further declines in size at age. We must be very, very careful not to fall into the pitfall thinking that more is better. I haven't decided if I support the S-1 program or not...need a lot more convincing.
