Chen, H.-Y.; Leu, Y.-T.; Roelants, I. (1992). Effective supplementation of arginine in the diets of juvenile marine shrimp, Penaeus monodon. Aquaculture 108: 87-95

Effective dietary supplementation of arginine was demonstrated in juvenile Penaeus monodon which can not effectively utilize crystalline amino acids in their diets. In an 8-week feeding trial, juvenile P. monodon (average body weight, 0.95 g) were fed casein-based purified diets supplemented with cellulose-acetate-phthalate (CAP) microencapsulated L-arginine, or glycerol-mono-stearate (GM) microencapsulated L-arginine. There was no significant difference in the growth-promoting effects and feed conversion among the CAP, FM and SAL groups. The mean final weight of shrimp fed the crystalline-arginine supplemented diet was higher than that of the group fed the unsupplemented diet but the difference was not significant. There was no statistical difference in survival between dietary groups. Success with CAP and GM microencapsulation of arginine supplementation appears to hold the most promise as a technique for quantifying the amino acid requirements of shrimp, and possibly other crustaceans and fishes.
