Saline brine shrimp are widely used as fish feed and easily found in aquarium stores, but in the scientific-technical field brine shrimp are gaining a lot of space and are increasingly in demand because they act as a natural bioindicator used in lethality/toxicity tests, as it is a cheap, effective and quick method to use. From the analysis of these studies, it was observed that there is a process for the hatching of the Nauplii (Artemia cysts) with a few steps, but yet, it requires great care, so that the environment is favorable to the hatching of the cysts. Considering that the water’s pH adjustment process requires greater care, cost and time, it was realized that there is a need for a method to facilitate and ensure its efficiency. Aiming at this, this project utilizes automation in pH control for hatching of micro crustaceans to improve performance and reduce unused time, as well as a way to standardizing and ensuring the quality of each stage. Hence, this project proposes the use of a pH sensor together with a water pump to control the alkalinity scale in order to adjust the environment to allow the hatching of the brine shrimp. In addition, lightning is controlled using a led strip, which is also necessary for hatching to occur correctly.
