The present work develops an automatic system that allows the counting and the measuring of a population of gray tilapia fingerlings. Nowadays, there are many processes in charge of the calculation of the geometric dimensions of the fingerlings that have a great subjectivity and spend a lot of time. In addition, removing the fingerlings from the water can cause stress to them, which it could lead them to death. In this way, it seeks to eradicate the manual intervention, thus a mechanical structure is elaborated which holds a fish tank and an enclosure with illumination and a second transparent tank. A transfer by samples of fingerlings from the first to the second container is carried out, for this purpose the grids controlled by motors are used to bring them closer or move them away from the bleed orifice of the first container. Also, a ball pneumatic electrovalve is used, which works as a gate that allows or forbid the passage of the fingerlings through the PVC pipe. Then, with the fingerlings in the enclosure, it proceeds to execute the counting and measuring algorithms of length and width. Satisfactory results were obtained because it has an accuracy of 98% in counting and 90% in length and width measuring. Furthermore, the time for the calculation of both parameters were reduced in comparison to the manual process.
