CMFRI claims to have developed app to measure fish size without touching them

The Central Marine Fisheries Research Institute (CMFRI) has claimed to have developed a smartphone application that can measure the length and width of fish without physically handling them. Named ‘Matsya Metri’, the application, which has been designed for fisheries scientists, researchers, and field survey teams, facilitates rapid and systematic collection of biological data to support fisheries assessment and management. The application was developed by Eldho Varghese, a senior scientist at the institute, according to a CMFRI release. Grinson George, director of the institute, said the application simplified biological data collection by automatically recording measurements and generating length-frequency datasets. The application allows multiple individuals of the same fish species or aquatic resource to be measured under a single sampling session. Once measurements are completed, the system automatically generates length-frequency distributions using appropriate class intervals. The recorded measurements and the corresponding photographs can be saved along with the sampling session and subsequently exported as a CSV file for further scientific analysis, according to the communcation.
