. While dietary supplementation with either inulin or JA did not affect blood triglyceride, cholesterol, BUN, T-bilirubin, D-bilirubin, SGOT, SGPT, and chloride contents, they did modulate several other blood parameters. For instance, both inulin and JA supplementation led to significantly increased blood glucose and albumin levels (P < 0.05) and increased total protein in blood, although significant enhancement in the latter was observed only in fish fed diets supplemented with JA (P < 0.05).
