In Dapeng Cove, Daya Bay, P.R. China, the range of water temperature
is usually 17–33 °C with a mean of ~25 °C in a whole year. However, in
the outside breeding ponds higher water temperature such as 35–36 °C
and lower water temperature such as 13–15 °C can be recorded in summer
andwinter for the restrictedwater volume. In fact, fish growth is dependent
on water temperature strongly, and too high or too low water
temperature will bring negative impacts on fish growth. In this paper
four water temperatures ranging from 23 to 35 °C with an interval of
4 °C were set, i.e. 23, 27, 31 and 35 °C. Furthermore, in order to describe
the growth-temperature relationships of cobia in more detail, and also
to determine the critical temperature atwhich cobia growth began to decline,
referred to the previous studies by Sun et al. (2006c) and Sun and
Chen (2009), another treatment of 33 °C between 31 and 35 °C was
added.
