18 years of otolith increment widths of barramundi (Lates calcarifer) in three catchments in the Gulf of Carpentaria

Abstract

Measurements of the otolith increment widths of barramundi in three regions in the Gulf of Carpentaria. Measurements were taken during the course of NESP Northern Australia Environmental Resources Hub projects 1.3.1 and 1.4. Otoliths were predominantly sourced from Fisheries Queensland’s historical otolith collection, supplemented with samples collected during FRDC project 2007/002. The comma separated values (csv) file contains the following fields:
- Region from which the fish was collected<br>- Unique reference ID for each fish
- The age at capture of each fish, used as a covariate in growth models
- The year class of each fish
- The year of growth represented by the increment being measured (range: 1997 to 2014)
- The otolith increment being measured (one, two, or three in most instances, unless the fish was less than 3 years old)
- The measured width of the increment, in mm.
