Summary

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.

Entity Information

Data Attribute / Type Description
Age_ID
Unknown 		Auto generated
Cruise_Station_ID
Unknown 		Auto generated
specimen_number
Unknown 		ID assigned to each specimen. Not unique (start at 1 every year).
depth_stratum_id
Unknown 		Depth stratum code (1-8)
species_code
Unknown 		RACE species codes
sex
Unknown 		m or f
age
Unknown 		age in years, subsampled from otoliths taken at each station
maturity
Unknown 		maturity code (1-6)
length
Unknown 		length in cm
weight
Unknown 		round weight in kg
error_flag
Unknown 		Numerical value described under ErrorDescription.
notes
Unknown 		Incomplete specimen if missing length, weight, or sex; Above Standard or Below Standard if residual is larger or smaller than a threshold value indicating that the weight is out of the normal range for the sablefish length-weight relationship (selects ~ 2 specimen per year); No Error if there is no missing data and length-weight combination is reasonable.
residual
Unknown 		Deviation from fit to sablefish length-weight data. See document on Flagging Specimen data for details.
