“…The addition of phytase, either solely or in combination with limiting AAs, significantly reduced total P waste of catfish fed with diets containing CM as replacement of 45% FM protein. The enhancement of P utilization and reduction of total P waste of fish fed with phytase supplemented plant-based diets have been reported in previous studies [17,5,[41][42][43][44]. The common explanations for the improvement of dietary P utilization were: (1) the liberation of chelated phytate-P by phytase leading to higher availability of dietary P [45]; and (2) the promotion of P deposition in fish by dietary phytase leading to higher P utilization and low P waste discharged by fish [46].…”

“…Some even believe that CM has a better amino acid profile than SBM [1]. Substitution of FM by CM has also been widely investigated for many fish species, including Chinook Salmon, Oncorhynchus tshawytscha [2][3][4], Atlantic salmon, Salmo salar L. [5], red sea bream, Pagrus auratus [6], rainbow trout, Oncorhynchus mykiss [1,7,8], tilapia, Oreochromis mossambicus [9], silver perch,Bidyanus bidyanus [10], sunshine bass, Morone chrysops x M. saxatilis [11], turbot, Psetta maxima [1] and channel catfish, Ictalurus punctatus [12][13]. CM has also been incorporated in diets for shrimp, such as white shrimp,Penaeus vannamei [14] and blue shrimp, Litopenaeus stylirostris [15].…”

Effects of dietary phytase, amino acid (AA), and inorganic phosphorus (P) in canola meal diets on the growth and P waste production of Australian catfish, Tandanus tandanus were evaluated. Fishmeal protein was replaced by 30% and 45% with canola meal protein in two separate experiments, in which test diets were fortified with phytase, AA, inorganic P, or their combinations. Addition of sole phytase to the 30% replacement diets did improve growth performance and feed utilization of fish compared to those fed with the non-phytase diet. Inclusion of phytase and/ or AAs did not improve the growth and feed utilization of catfish when fishmeal protein was replaced by 45% while adding inorganic P showed significant improvement in the performance of the fish. Ortho-P waste was significantly lower while total P waste was significantly higher in fish fed with canola meal diets at both levels of fishmeal replacement. Phytase did not affect the total P waste of catfish but a combination of phytase and AA resulted in a significant reduction. Dietary inclusion of inorganic P significantly elevated the total P waste of catfish compared to that of the control fish. It was concluded that the use of canola meal in combination with inorganic P in diets for Australian catfish could significantly increase nutrient pollution in aquaculture

“…The results of the present study indicate that phytase in the diets improved P and protein retention. It is also reported that improved P retention was found with phytase (2000 FTU/kg diet) supplemented in soybean meal and canola meal diets in striped bass (Papatryphon 1999) and in Atlantic salmon (Sajjadi et al 2004). In our study, phytase enhanced protein retention, suggesting that phytase reduces formation of phytate-protein complexes in the gut and causes an improvement in utilization.…”

An experiment was conducted to investigate the effect of phytase supplementation on weight gain, phosphorus and protein digestibility and retention in Japanese flounder (Paralichthys olivaceus) fed a soybean meal (SBM)-containing diet. Six levels of phytase-supplemented diets containing 0, 150, 300, 450, 900 and 1500 FTU (phytase unit)/100g diet were assigned to triplicate tanks and fed to Japanese flounder (20 fish/ tank, initial average weight 151.4 g) for 40 days. The increase of soluble phosphorus and decrease of phytic acid remained relatively constant for all levels receiving the 300 FTU diet and greater. Significantly (P<0.05) greater weight gain and higher feed conversion ratios (FCR) were observed in fish fed diets supplemented at 300 FTU or greater compared to the control (0 FTU) diet. Significantly (P<0.05) improved apparent protein and phosphorus digestibility, as well as serum calcium concentration were found in fish fed the 300 FTU diet. All Effects of phytase addition on P utilization in Japanese flounder diets supplemented at 300 FTU or greater also showed a significantly (P<0.05) improved concentration of bone calcium and zinc. The 150 FTU inclusion level showed only better protein and phosphorus retention, bone phosphorus and magnesium than the control (0 FTU) diet. Therefore, this study indicated that supplementation of phytase is effective and that the 300 FTU/100g SBM-containing diet resulted in the maximum release of soluble phosphorus, and as a consequence improved weight gain, FCR, bone minerals, phosphorus and protein digestibility and retention in Japanese flounder.

“…On the basis of these facts, some phytase preparations have been formulated and used to reduce IP 6 and IP 5 levels of some plant-based foods (Haros et al, 2001;Saito et al, 2001;Porres et al, 2001: Matsuo et al, 2005 and also animal and fish diets (Pallauf & Rimbach, 1997;Sajjadi & Carter, 2003).…”
