Phytase may be present in plant ingredients or may be produced by microorganisms. The indigestible phytate enzyme is very specific to hydrolyze that is present in plant protein sources. Some fishes cannot produce this enzyme like mono gastric fishes and cannot hydrolyze the phytate. Moreover, supplementation of phytase in fish feeds has been generally reported to improve the utilization of plant phosphorus (P) by fish and the bioavailability (Cao et al., 2007).
The feed industry of aquaculture uses fish meal due to its source of vitamins, minerals, amino acids, essential fatty acids and growth factors (Zhou et al., 2004). However, high prices, rising demand and unstable supply of the fishmeal with the extension of aquaculture makes search of sense and introduce alternate sources of protein (Lim et al., 2011).
Among citric acid and organic acids, because of high buffering capacity and unique flavor, has been extensively used for diet acidification (Hossain et al., 2007;). The great potential of citric acid to replace fish meal up to 70 percent in low phosphorus containing plant protein diets (Sarker et al.,
