Análisis de la variabilidad de pH y sistemas de carbonato en piscinas camaroneras en el estuario del rio Cojimíes.

Abstract

This research analyzes the carbonate system in shrimp farming ponds (Litopenaeus vannamei) in the Cojimies River estuary, Ecuador, within the context of ocean acidification, a climate change-related phenomenon that impacts marine biodiversity and aquaculture productivity. Given the economic importance of the shrimp farming industry, understanding water conditions is essential to mitigate climate change impacts and promote sustainability. The study was conducted in two locations: Daule, characterized by a mix of freshwater and saltwater, and Cojimies, with a stronger marine influence. During three cultivation cycles, pH, temperature, and salinity were measured in situ, and total alkalinity samples were analyzed in the laboratory. Data were processed using CO2SYS software to calculate parameters such as pCO₂, tCO₂, and the saturation indices of aragonite and calcite. Statistical analyses were performed to compare variations between locations and cycles.
