Physiological and growth response data of the Peruvian scallop Argopecten purpuratus during a 51-day factorial experiment under hypoxia and seawater acidification

This dataset contains the physical, biometrical, and physiological parameters of the Peruvian scallop Argopecten purpuratus collected during a 51-day laboratory experiment. The study followed a 2×2 factorial design crossing two oxygen levels (Hypoxia 20% sat. vs. Normoxia 100% sat.) and two pH levels (Low pH 7.4 vs. Normal pH 7.8). Data includes daily environmental monitoring of the experimental tanks (temperature, pH, dissolved oxygen, salinity and total alcalinity), daily survival rates, and bi-weekly measurements of shell height, dry weight of tissues ( gonad, flesh, shell), and physiological indices such as the gonadosomatic index, Fulton's condition index, standardized clearance and net calcification rates.This dataset supports the findings on the article Trade-off between growth and reproduction in Argopecten purpuratus (L.) scallops exposed to medium-term hypoxia and acidification.
