To better understand whether the low pH and high pH conditions commonly found in aquaculture culture systems affected the success of the settlement stage of the sea urchin Centrostephanus rodgersii, we induced larvae to settle at pH 7.6, 7.8 (created by injecting CO2), 8.1 (ambient), 8.2, and 8.3 (created by raising total alkalinity), and followed post-settlement growth, development, and survival for 16 d. At metamorphosis, low pH significantly increased the occurrence of abnormalities and reduced the number and length of the sea urchins spines and pedicellaria, but did not affect settlement rate or size compared to ambient pH. Synonyms: ragamuffin, waif, guttersnipe, brat More Synonyms of urchin. For example, sea urchin larvae exposed to acidified seawater (0.35 kPa CO2, pH 7.25) maintained a fully calcified larval phenotype, albeit at a reduced rate of body growth (4).
