Eight randomly selected fish from each tank were weighed out
at days 7, 14, and 28 after the feeding trial, respectively. Growth
performance and survival rate of P. bocourti were calculated using
the following equations: specific growth rate (SGR) ¼ 100 (ln
final weightln initial weight)/total duration of experiment; feed
conversion ratio (FCR) ¼ feed given (dried weight)/weight gain
(wet weight); survival rate (%) ¼ (final fish number/initial fish
number) 100.
