Commercial Fisheries Database Biological Sample (CFDBS)

Age and length frequency data for finfish and invertebrate species collected during commercial fishing vessels. Samples are collected by fisheries reporting specialist from fish dealers in ports along the northwest Atlantic Ocean from Maine to North Carolina.

The age and length data is used to characterize the fish populations in stock assessments.

Time series containing the age of individual finfish and invertebrates species by length. Length frequency data by species.

Oracle 11g data processing procedures

Biological samples are collected based on sampling requirements provided by the stock assessment requirements

Accuracy of species identification is determined by comparing the biological samples with the information from the fish dealer reports and the vessel trip reports.

Routine audits are run as the data is entered and post audits are run when the master data sets are created. The Age and Growth staff also run reports which produce age/length keys which are used to detect outliers.

Data archived at NEFSC but may also be archived at TBD location.

Data is backed up as entered into the Oracle data tables

Data is collected by fisheries reporting specialist at the ports from fish processors; data is entered into a web-based data entry system by reporting specialist; age structures are sent to Age and Growth department for processing; age of fish are added to the age data set by Age and Growth staff; data is processed to master data format by database manager for CFDBS.
