We determined biliary bile salts levels in red sea bream fed on either fish meal or alternative soybean meal for 33 weeks. The feeding of soybean meal showed smaller body weight gain and higher mortality. No significant difference was observed in hematological parameters such as hematocrit value, plasma enzyme activities, and protein level between the groups. However, the biliary bile salts concentration in soybean meal group was significantly decreased following the reduction of plasma cholesterol and taurine levels, when compared to that in fish meal group.
