Resumen

Knowing the biomass information of fish in a hatchery is of great importance to determine the food quantity to supply and harvest fish. It is difficult to estimate their number and size due to the area’s high number of fish and conditions. Unlike the traditional method based on the individual manual measurement of each fish, which usually causes stress and damage to the fish. There are less intrusive methods, such as the use of underwater cameras for information gathering. They are becoming more common among researchers. However, this system has a limitation referring to the high cost that its application to multiple cultivation areas could have. Below, we propose a Low-Cost (350 USD) and simple design prototype camera system for underwater monitoring, made with elements that are easy to purchase and implement. Its small size allows for easy installation in the hatchery. It can work as deep as 10 m and has enough autonomy to record more than 8 h of video. An electronic system capable of capturing video based on a StereoPi board and Raspberry pi uses a pair of cameras to form a stereoscopic vision to generate a disparity map. With the collected samples, a data set of images was created. To contact and download the obtained dataset you can go https://compsust.utec.edu.pe/wnina/datasets here.
