The Otolith App for Image-Pro Premier streamlines the analysis of fish otoliths (inner ear structures) and scales. By partnering with leading fish biologists from around the world, who are also Image-Pro experienced users, we consolidated their best practices into a dedicated and simple work flow.
The Otolith App enables fish biologists, ecologists, and research technicians to consistently and expediently determine age, growth, mortality, and physiological condition of fresh and salt water species from otolith's and scale's ring microstructures (e.i. annuli and circuli). The tremendous gain in productivity facilitated by the Otolith plug-in has allowed fish facilities to undertake more ambitious studies.
Through a few simple steps Premier's Otolith App guides the user through the detection, measurement, and editing of otolith and scales' growth lines (i.e. annuli and circuli). The annotated growth marks are burnt onto the image.
The Otolith App guides Image-Pro's users through an optimized protocol that combines automated, semi-automated and manual steps, while Image-Pro's powerful algorithms work in the background. Users, however, still retain the freedom to edit their results to their satisfaction, and to annotate and format them to their taste.
Image-Pro Premier's plotting options allow users to visualize details of their measurement results. The results table and graphs can be exported to excel and summarized in reports with customizable templates. The convenience of the different options for data archival within Premier makes it for user to organize and retrieve analysis results.
A clear advantage of the Otolith App is that offers a consistent methodology for carrying out multiple measurements of diverse groups of samples. Results' variability across technicians is thus minimized and easily verified.
