Age and size in market samples of geoduc clams (Panope generosa) / by R.M. Harbo, B.E. Adkins, P.A. Breen, & K.L. Hobbs. : Fs97-4/1714E-PDF

"Eight lots of geoducs harvested by the commercial fishery were sampled at processing plants. Each individual was measured In shell length, shell weight, and total wet weight. The heaviest individual measured was 2198 g. Shells were collected and later aged with the acetate peel technique. Geoducs recruited to the fishery beginning at age 4, and appeared to be fully recruited by age 12. The mean ages in these samples varied from 28 at Tofino to 61 at Spider Anchorage. The oldest individual was 146 years old. Mortality rates calculated from age frequencies were found to range from M=0.003-0.021. Growth rates determined from age, length and weight data, were similar to those found In other studies"--Abstract, page iii.
