(a) Schematic of experiment setup for days 0–3. One header tank was adjusted to each of the four temperature and pH level combinations. Each header fed three experimental tanks. Embryos were placed on the floor of each tank. As embryos hatched, larvae would be pulled through into the second tier of tanks, which included silos to prevent loss of abalone. Larval abalone lived in these silos until day 10 of the experiment or until they were removed for settlement trials. (b) Schematic of experimental setup for days 3–10. On the third day after fertilization, the embryo tanks were removed from the system, so the header tanks fed directly into the larval silos.
