Excerpt from Distribution of Spawning Pink Salmon in Sashin Creek, Southeastern Alaska, and Survival of Their Progeny Although the upper area was highly productive of pink salmon fry, it has had intensive spawning only in years when the density of spawners was high. When the density was low, spawners tended to concentrate in the lower area. The validity of the supposition that only highly productive spawning beds are used when escapements are small is questioned. The observations at Sashin Creek indicate that relatively large escapements help ensure complete use of productive spawning beds.
