Catalogue of Length Frequency Data

This page provides the ability to search a catalogue of length frequency samples collected by Ministry observers, and from research trawl surveys. The catalogue is updated automatically (approximately once every week) from the contents of the Ministry's cod and trawl databases. Note however that although summarised research collected length frequency data may be available in MARLIN shortly after the end of the survey, several months may elapse between a length frequency sample being collected by an observer and a record of that sample appearing in the cod database, and subsequently into MARLIN.
