A fish reference database is an electronic database that typically contains DNA barcodes, images, and geospatial coordinates of examined fish specimens.

Sample – A relatively small part of a fish stock which is removed for study, and which ideally is representative of the whole. The greater the number and size of the samples, the greater the confidence that the information obtained accurately reflects the status (such as abundance by number or weight, or age composition) of the stock.
