The diet of river lamprey consisted of approximately 90% herring and 10% salmon. During July and August the sex ratio of males and females was almost identical, however, the sex ratio for the total sample was approximately 60% female and 40% male. Lamprey scars were observed on 0.079% of the juvenile salmon and 1.92% of the adult salmon examined. Pacific lamprey were not found in association with river lamprey except in the vicinity of the Fraser River. The report also contains catch data and length frequency measurements for salmon, dogfish, Pacific hake, and pollock"--Abstract, page iii.
