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.
