This document shows the design of a temperature and level controller for a pond with fingerlims; besides it has an automatic system which provides food to the fingerlings present in the pond at stipulated times according to the program, which depending on the species of fingerling has certain characteristics to develop in its environment. The system has a main power board supported by an emergency board (UPS), which will be feeding the various sensors and equipment that interact in it, on the other hand will be the instrument panel which contains a PLC that is connected to the different sensors and equipment that intervenes in the system, programmed to perform different actions according to the information provided from their interconnections. Taking into account that the water must have a circulation cycle due to the feces and alkalinity of the water, an opening of the outlet valve of the water and inlet must be made, so that it is treated by means of filters and can return to the environment or in its defect will be reused again in the system.
