Impacto de la exposición prolongada a condiciones de bajo pH en el crecimiento y actividad natatoria en la acuicultura del camarón (Litopenaeus vannamei).

Abstract

Ocean acidification is the process where the pH of seawater decreases due to the alteration of carbonate chemistry due to high concentrations of CO2 in the atmosphere, projections suggest that this may intensify in the coming years. These processes affect different marine invertebrate organisms including crustaceans, this study aims to analyze the impact of prolonged exposure to low pH on the growth and swimming activity of the Pacific white shrimp Litopenaeus vannamei, where a significant alteration in growth was found for the highest level of acidification applied pH = 7.15 showing a greater increase in size, on the contrary, for swimming activity a significant reduction could be seen in the final period of exposure compared to initial values of the experiment, being Ecuador one of the main producers of shrimp in the world.
