Abstract

ICAR-Central Marine Fisheries Research Institute has developed a smartphone application MatsyaMetri that can measure the length and width of fish without physically handling them. The app has been developed under a project for the automated measurement of aquatic resources and the generation of standardised length-frequency data used in fisheries stock assessment. The app enables users to capture images of fish and estimate their dimensions using an intelligent, image-based measuring tool. The measurements are automatically recorded and compiled into length-frequency datasets, which are used for fisheries population analysis, stock assessment and resource monitoring. The application is aimed at simplifying biological data collection during field surveys and supporting more systematic generation of fisheries data for scientific assessment and resource monitoring, said Eldho Varghese, senior scientist and ICAR-National Fellow, who developed the application.
