“…Nevertheless, the pCO2 level of the present study was representative of the natural conditions found in the Peruvian upwelling system (Friederich et al, 2008). Furthermore, the experimental conditions (pH, temperature, and food) established in this study allowed us to achieve a growth rate in the control (0.33 mm d -1 ) that was close to those found in natural conditions, ranging range from 0.20 to 0.39 mm d -1 for individuals with a height of 10 to 23 mm (Aguirre, 2011;Alcazar and Mendo, 2008;Cisneros et al, 2008). Similarly, in a study carried out with A. purpuratus in Chile, Lagos et al (2016) achieved similar growth rates between the control and the natural growth rates of 0.08 to 0.17 mm d -1 that are found naturally in Chilean bays (Avendaño and Cantillanez, 2008;Ramajo et al, 2020).…”
