To develop a database of high-quality, standardised otolith images for use in developing an automated ageing system using machine learning.
Information on the age structure of fish species is essential to understanding stock recruitment and developing age-based fisheries stock assessment models. Otolith analysis is the standard method of age determination but this process is time consuming and represents a significant cost to Fisheries New Zealand.
Digital image analysis could save a significant amount of time that is currently spent manually ageing otoliths as well as reducing subjectivity in otolith reading, which is currently dependent on the accuracy of the individual otolith reader. This would enable more otoliths to be read per year as well as providing a digital archive of otolith information.
