Here's a link to an abstract of the study:

From the abstract:
"In all treatments, the maximum dark-adapted quantum yield of photosystem II (FV/FM) of the larvae was ∼49% lower than that of adult corals; FV/FM in the larvae also differed among temperature treatments,
with the highest values in the fluctuating treatment."
The fluctuating treatment that the article refers to is varying the daily water temperature between 21C and 28C.
