Evaluation of circulating insulin-like growth factor (IGF)-I and IGF-binding proteins as growth indices in rainbow trout (Oncorhynchus mykiss)

•Serum IGF-I and IGFBP-2b are growth indices in trout.•Serum IGFBP-1a and -1b were hardly detected even after fasting.•An unidentified 32-kDa IGFBP responded to fasting/refeeding. Circulating insulin-like growth factor (IGF)-I has been proposed as a growth index in several teleosts, including salmon...
