The African lung fish, Protepterus annectens (P annectens) is a highly priced food fish in Nigeria. The main objective of this study was to examine the fish and to provide the knowledge of its serum biochemical parameters during active state and hibernation period. The results of biochemical profile of P. annectens in this research showed higher values during active state except serum protein that showed higher value during hibernation period. This information may perhaps be very vital for effective exploitation, sustainable management and conservation of P. annectens.
