Desing and construction of a portable devica for counting red tilapia fingerlings
Keywords:

Commercialization of fingerlings is carried out by units and not by weight in the fishery sector of the country, under the argument that it is required to know the exact amount of food and definition of population densities. The proposal consists of an automatic device with variable tilt, portable processing unit by using free software, internal artificial lighting and touchscreen for the count of red tilapia fingerlings between 1 and 2cm in size. The device is validated starting from the isolation of the external light and effectiveness of the internal artificial illumination, suitable angle of inclination to obtain appropriate rates of descent, validation of the accuracy of the realized counting and comparison of times with the traditional manual method. A device with the expected lighting characteristics, count with an error of less than 2%, low cost and portability required in fish farms are obtained.Article Metrics
