Abstract
This thesis examines two phases of sea urchin aquaculture; the transition from larvae to juveniles (settlement) and growth of juveniles until harvest (grow-out). In the settlement phase, settlement inducers boosted settlement rates, but not survival. Optimising temperature, seawater carbonate chemistry and larval development boosted survival. In the grow-out phase, high densities and low exchange rates decreased growth and gonad production of juveniles and adults due to increased pCO2 and decreased alkalinity of culture water. Understanding how biogenic acidification and climate change may interact to affect production of calcifying invertebrates is a crucial challenge to efficient aquaculture into the future.
