For a decade we clipped all our coho to study our hatchery’s effectiveness. When the coho returned, all were meticulously checked one by one for clips and tags so we can have irrefutable proof of what we already know, our program is highly effective. This graph represents a complete population census and not an arbitrary […]

  2020 was another successful year for Lang Creek Returns. Chinook and Coho had terrific showings this fall with both of their numbers at the higher end of what we typically expect. Our Chum returns weren’t high compared to historical numbers, but we more than doubled last years returns. You may recall, last year Chum […]

  This chart shows our hatchery Chinook releases offset with Lang creek returns 4 years later. Though we don’t control what happens in the ocean, the trendlines show that our production correlates with successful average returns over time.

This chart is an annual comparison of Chinook average fecundity (eggs per female).

This chart is used to predict what we might expect for Coho returns in the fall based on how many show up in August.  

This chart compares the return numbers of our Chinook between September and October. Its interesting to note that our Chinook run timing has been trending earlier in recent years.

  This chart shows correlation in the return numbers for Coho and Pink.

This chart shows a correlation between fish size and fecundity (number of eggs per female).
