Latin square disigned digestible experiment was conducted in fish named Anabas testudineus Bloch, 1792 to identify digestibility of dry matter (DM), crude protein (CP) , ether extract (EE), crude fiber (CF) and ash in 5 experimental dietaries that contained 5 different CP levels (20 percent, 24 percent, 28 percent, 32 percent, 36 percent). The results shown that environmental factors were in line with performant and development capacity of this fish. The digestibility of DM, CP, EE, CF in diets contained different CP levels were significant different (P0.05). Higher level of CP (20 - 32 percent CP) in the diet higher digestibility of DM, CP, EE, CF, Ash (y
