Description of the activities of the project
  • Fish sampling is the daily routine in all fish production farms and also fish research infrastructures. The sampling is performed to determine several fish traits to analyse fish development during the time. The industrial sampling is mainly used for fish sorting based on fish growth. The weight, length and fish appearance (damages, deformities) are usually measured. The research sampling is specified by the research question of the experiment. The weight, length, fish ID, and fish appearance are the main parameters that are determined. The common sampling procedure is based on manual sampling combined with the fish's individual identification using PIT technology. It is a time-consuming process and needs to be anaesthetised. The staff weigh the fish, measure the length, visually inspect the fish, take the picture, read the PIT tang and do some other sampling.
  • The process could be simplified by automating the sampling unit. The fish can be placed (sliced through) in the sampling unit equipped with the camera, scale and PIT reader. The software automatically detects the fish, measures fish dimensions from the image, records the PIT number, reads the weight from the scale, and makes an image-based fish appearance analysis. The PIT identification can be substituted by the individual identification from fish appearance (pattern on the body).
  • The aim of the project is to design the prototype of an automatic sampling unit and develop the software for fish detection and parametrisation.
  • The students will learn how to design the sampling unit, how to read the information from digital devices (scale, PIT tag reader), and how to implement the software for fish detection based on CNN, and integrate automatic fish identification using the PIT reader and fish appearance.
