Water quality assessment in shrimp culture using an analytical hierarchical process
José Juan Carbajal-Hernández,José Juan Carbajal-Hernández,Luis P. Sánchez-Fernández,Luis A. Villa-Vargas,Jesús Ariel Carrasco-Ochoa,José Fco. Martínez-Trinidad +5 more
TL;DR: In this article, the authors developed a new Water Quality Index focused on monitoring of shrimp farms; detecting poor water quality and preventing negative effects in the ecosystem, which assigns a priority level to each water parameter through a new analytical hierarchical process (AHP), which allows an accurate assessment of the water quality.
