Trinity River Hatchery Trapping Summary 10/30/2014


Trinity River Hatchery Trapping Summary Update for Oct. 22 to Oct 28.


Fall Chinook Salmon counts begin and what is considered to be Spring Chinook has ended.

Total combined Chinook increased this week from 69 to 391.

Total combined Steelhead decreased from 7 to 0.


1. Hatchery summaries are not always posted on a weekly basis due to the large amount of data collection and entry.

2. All hatchery totals are complete counts of what has been processed at the facility.

3. Hatchery totals do not include fish which are being held in on-site ponds for ripening and future spawning.

4. There is a break in spawning operations, usually in October, to facilitate separation of spring and fall-run Chinook salmon.

5. The hatchery serves as the main recovery point for fish tagged at the two weirs (Willow Creek and Junction City).
