Notes | Estimated reticulate sculpin populations in three study streams and their predation on coho salmon fry. The sculpins disappeared from a large stretch of clearcut-without-buffer strips Needle branch, "probably due to the very low dissolved oxygen levels.." Slash burning killed sculpins. Did not find likely predation on coho salmon fry within stream gravel beds, because the sculpins did not penetrate deeply into the gravel. While larger sculpins did feed on salmon fry, the sculpins were not deemed significant threats to salmon. Major professor was H. J. Rayner. |
