Diseño de un sistema de control aplicado al proceso de cría de larvas de camarón para el Grupo Empresarial LARDEMA, módulo San Juan.

Abstract

The purpose of this study was to contribute to the shrimp sector in its larval production phase, through the design of an automated control system. It is intended to intervene the larval rearing process to maintain the appropriate parameters of temperature, feeding, salinity and pH in the tanks, in order to reduce the mortality rate of the species and improve productivity per run. For this purpose, a descriptive research was carried out based on the diagnosis of the productive infrastructure of the San Juan Module belonging to the LARDEMA Business Group. Among the main scientific findings, a high level of incidence of preponderant factors such as temperature, alkalinity and poor level of precision of food on the production process of nauplii was found. Fulfilling the proposed objectives, a thermal control system was designed through the installation of alarms with ranges to alert the low or high temperatures in the tanks, using automatic sensors that turn on to heat the water to 33 ° C and to cool the water in case that due to the effect of the ambient temperature, it is required to reduce it to 33 ° C. Additionally, the design has a digital system that regulates the alkalinity levels of water in reservoirs. The system consists of a sensor that diagnoses the salinity of the water when entering the tank that turns on a peristaltic pump for salt water dosing, and another one for fresh water for the regulation of the environment in 30 parts per million. Finally, a feed irrigation system for dry and liquid diet is integrated through the activation and deactivation of pumps that will dose the food to the tank until the timed amount of food required is provided.
