Post‐metamorphic impact of brief hyposaline stress on recently hatched veligers of the gastropod Crepipatella peruviana (Calyptraeidae)

15 days post-metamorphosis) and CR (15 days post-metamorphosis) were not different from the control treatment with an average value of 1.7 (×10−2 mg O2 h−1 juv−1) and 0.07 (L h−1 juv−1) for OCR and CR at 15 days post-metamorphosis, respectively. Also there was no effect on juvenile growth rate. This study shows that short hyposaline events suffered by early veligers of C. peruviana can cause reduced size at metamorphosis and potentially reduce juvenile survival, factors that could affect the fitness of future adult populations.
