Time for my yearly bitching about the mis-management of steelhead on the Chilliwack-Vedder River. I won’t get into the fact that the most heavily fished steelhead river in BC, which brings hundreds of thousands of $$ to the local economy of the Chilliwack area has no adult and very limited juvenile stock assessments; that’s a different topic for another post. This rant is about the hatchery program. Last year I posted this on FWR and to say the least the response was underwhelming:
Recently the Chilliwack River Hatchery released its annual batch of steelhead juveniles. And for the second straight year these juveniles were undersized – indeed I’m told these are the smallest juveniles ever released from this facility. As a general rule, smaller juveniles means poorer survival and increased residualization. As I understand the issue, DFO is mandated by the Province to produce 80g juveniles in one year. This is doable if warmer well water is used to augment the cooler river water and if the fish are fed appropriately.
DFO is under major budget constraints and the steelhead program is suffering for it as again this year, to save money the fish were kept on mainly river water and fed 60% of there optimum ration.
For those that like this steelhead hatchery program, you should be upset that many of these undersized juveniles will become merganser and heron food. Future hatchery returns will be considerably smaller.
For those that are against this hatchery program, you should be seriously questioning the rationale of removing up to 80 wild fish from this system every year, when populations are unknown.
Well, this season is no different and in fact the juveniles now rearing at the hatchery are smaller than at this time last year. There is no timeline to put these fish on warmer well water, if at all, so again undersized parr will be released this spring.
As I see it these are our options:
-embarrass the Province, who contribute squat or DFO, who fund it all, through a media/email blitz to fund the feeding and electrical costs to pump well water. This is app.100k annually.
-cut back broodstock capture by about ½ so the fry from 40 wild adults (as opposed to the present 70-80 adults captured) can be reared under better conditions to achieve better growth. This of course means fewer returning hatchery adults, but 40 more wild fish spawn
-stop broodstock capture completely, leaving the river for wild fish only (my personal favourite)
-use hatchery fish for broodstock, using limited well water (my least favourite option)
The few of us who live and breathe C-V steelhead would like to hear your comments.
