Item Identification

Title: Ages
Short Name: Ages
Status: In Work
Abstract:

Since 1996 sablefish have been randomly sampled throughout each set for ageing. For samples from 1996-present, maturity, length, weight, and sex is available for all sampled fish. Specimen are then sub-sampled for age reading and so ages are available for only a subset of these fish. This tableincludes data from sablefish that had their otoliths sampled for aging, but were not always aged.
