Title: Steelhead Brood Capture Resumes Today
Post by: chris gadsden on March 01, 2012, 01:32:45 PM
The Chilliwack River Hatchery  Brood Capture program resumed today after taking a break for a couple of weeks. The hatchery boys were busy today picking up some nice wild steelhead from the volunteer anglers. When hatchery staff picked up the wild buck from me around 11 AM it was the 6th one of the day. I am please to have tubed 4 this year for the hatchery.

 The crew informed me they now have all the does they need and will be taking a few more bucks. Usually around 70 fish is the number needed to provide hatchery steelhead for the future and for you, That is if you like the odd one to take home for the table.

Brood capture wrapped up today as staff picked up the last 3 bucks (total 35) needed for the 2012 program. Thanks to all volunteers who carried tubes and others that contributed fish to the volunteers, that will insure we have hatchery steelhead in the future for those that like to keep fish for the table.

35? so maybe we are expecting like how many fish in 2016 or 2017?

A total of 70 steelhead (35 does, 35 bucks) are taken for brood. What the returns will be is hard to say as of course a number of factors come into play during each cycle. We of course never know what will happens in the ocean before they return to the Chilliwack Vedder River system.
Lets hope it keeps pace with the last 2years.

If they would keep trout fishing to catch and release until september 1st I know that would see the PRESUMED Ocean survival climb substantially.
I have seen far too many bags full of hatchery and wild smolts wiggling their way back to peoples cars in july and august, crying shame really.

Rod, the problem is these hatchery parr are released to small; not all will smolt and migrate.  The solution is to ensure the hatchery releases fish of sufficient size; they need to be reared on warmer water and fed more. That means it costs DFO more money to raise fish over which they have no jurisdiction.

Are these wild steelhead that are used for broodstock released back into the river, or are they killed during the egg and milt recovery process?
 I only recall seeing the chum worked on at the Chehalis, but salmon die at spawning anyway. I am just curious.
Thanks

Dave I am not sure what the size of the smolts are at release time would have to do with the mass killing of both wild and hatchery smolts during july and August. Every year while i am angling for Chinooks I see guys indiscrminately killing wild and hatchery smolts way past any limits. I am suggesting that keeping the river catch and release during this time might keep these anglers at the stocked lakes instead.

The Chehalis Steelhead that we captured for Fraser Valley trout hatchery were live spawned then released in the Fraser, that was about 5 years ago.

Vedder River is a different program so not sure how they do it, member Buck would have those answers for sure.

They have air spawned them in the past.

Rod, larger sized smolt releases invariably leads to increased adult returns. If the juvenile steelhead parr released from the hatchery migrated from the system, as smolts do, this would not be an issue. Problem is the fish released by the hatchery are not smolting, so they residualize and are caught by anglers, gulls, mergansers, herons ...
I do agree wild juveniles should not be harvested but C&R on rbt while chinooks are open would be impossible to enforce - really, FO's are on the Fraser at this time and CO's are busy with bears.

Chilliwack hatchery steelhead are air spawned and that's another rant for another time ;)

Yeah, the enforcement issue is definitely a valid point during said time period. But at least the guys who actually follow the rules might choose to fish during said stocked lakes during this time when they hear through the grapevine or at a tackle shop [assuming they dont read regs] there is no retention of hatchery 'trout'.

Based on what I have gathered from different hatchery staff, the bucks do very well, and almost always swim away happily and relatively healthily. Most females which are air-spawned do not usually do very well afterwords...if they survive to the point where the staff put them back in the river, I have high doubts that they will survive for very long after [how would they ever get mechanically injected air out of their bodies? well they wouldn't...]. All else being equal, that's the price we pay for a [pretty decent] hatchery steelhead program.

What is "air spawned"?

I'm curious as to the reasoning behind this hatchery rainbow trout opening. Does anyone know why it is there? I'm guessing that the number of smolts released is larger than necessary to produce the desired number of returning adults so as to allow a summer hatchery trout fishery. Am I correct?

I totally agree about the concern for killing of wild smolts. This needs to be addressed.

Lets get some terminology correct first in this discussion before continuing. ;)

Juvenile salmonids that are still in the river prior to migration are parr. Smoltification is a transition that takes place in the estuary as fish migrate through it. When completed, they are known as smolt. :)

The reason behind a hatchery rainbow trout retention opening in July and August is to eliminate juvenile hatchery marked steelhead that are released but do not migrate into the ocean because their release size is too small. Reducing the number of hatchery steelhead from becoming resident trout is a management decision to keep these fish from interfering with other river inhabitants. They can become potential predator of future juvenile salmonids and other resident fish, etc.

That all sounds good if this is done correctly. As Rod has pointed out, excessive killing of both hatchery marked and wild trout have been happening on the Chilliwack River in July and August. If we are to continue this fishery, then there needs to be a better outreach program so participants are well informed before taking part. To make sure participants are more informative, you need to know who they are. In July and August, these are kids coming with parents to the Chilliwack River recreational corridor for the summer holiday, these are teens who come to Cultus Lake with their peers to party, these are city folks who are out for the weekend to enjoy the great outdoor experience. These are people who are probably picking up their fishing gear from Canadian Tire and Walmart, or cannot differentiate between a salmon and a trout, nevermind the differences between a hatchery and a wild fish.

Personally I have no immediate solution for something like this. If this isn't the priority of enforcement in July and August or if ministry staff don't think this is an issue or if there is no money to keep people informed, it'll continue the way it is. I usually add a little write-up on our homepage and the Lower Mainland fishing report so hopefully some actually see the information before they go out for the first time.

Thank you for clearing this up, that makes total sense now.

Ahh, yes. Frustrating but true. Another suggestion would be to post signs at the popular camping sites showing people the difference between the species which you can keep and the species which you can not, as well as the difference btwn hatchery and wild fish, along with RAPP line and the possible fines/penalties they face. Similar to the Cultus Lake sockeye posters which still remain in certain locations.

Thanks Rod. It's call very clear now. Given that the enforcement officers have other priorities at that time of year, some good, well-placed educational signs and a few "ambassadors" to patrol the more popular camping locations might help. The money for these would have to come from a environmental funding program of some sort. Food for thought  ;)

I've always believed that an educational handout for different fisheries in the Fraser Valley is needed if we are encouraging people who have never fished before in Metro Vancouver to take part in fishing. There should be a one-page handout for the Chilliwack fall fishery, trout fishery, Fraser salmon fishery, etc. The handout can list the general regulations that they should know as well as specific regulations for that fishery, fish ID pics, contact number for RAPP, etc. They can be distributed from campsites, resorts, stores where rods are sold. This would be a good task for a local organization like the Fraser Valley Salmon Society, BC Federation of Drift Fishers, or the Steelhead Society of BC to invest in.

 Rod, all wild stealhead are air spawned and held for a 2 day recovery period before being released back into the Chilliwack River.

Thanks Buck

What percentage of the females survive air spawning? An earlier poster suggested survival was low.
