[env-trinity] 2024/25 CDFW Trinity River Project trapping summary through Julian week 1 (January 7)

[Lindke, Kenneth@Wildlife]

Folks,

Please replace the version I sent yesterday with the one I've attached here. Thanks to the careful attention of a couple recipients of the trap summary, I fixed an error in the number of adipose fin clipped steelhead in Julian week 51.

Folks,

Please find attached the TRP trapping summary through JW3 (January 21). The only trapping we're still doing is at Trinity River hatchery, and spawning there is now exclusively focused on steelhead. One very late arriving fall Chinook entered the hatchery on January 14th. Otherwise it has been all steelhead which will continue into March.

Hello fellow fish enthusiasts,

I hope this finds you well and optimistic about a new year ahead. Please find attached the TRP trapping summary through JW1 (January 7th). For those of you who don't know me, I have worked along side Mary Claire since 2017 and I will be taking over some of her responsibilities in her retirement, including distributing this trap summary.

With the exception of a few stragglers since Christmas, the salmon run to Trinity River hatchery has come to a close with lack luster returns for fall Chinook and Coho. Operations have shifted to steelhead spawning with a notable uptick in returns of half-pounders. Well, at least half-pounders as we define them to be less than 42 cm fork length, which doesn't necessarily mean they exhibit a true half-pounder life history.
