| Sumario: | Bio-energetic dynamic penaeid shrimp growth model was developed from an existingmodel on tilapia growth. The model was divided into 6 sub modules: (1) Moulting; (2) Feedconsumption; (3) Digestion and biosynthesis; (4) Energy metabolism; (5) Oxidation; and(6) Growth; and was parameterized based on the literature. The model was calibrated andvalidated with an independent data set.For calibration, the best agreement between observed and simulated value for growth wasachieved when it was assumed that 14% of dietary amino acids was converted to glucoseand ratio of fat: protein for energy generation was 0.819. Calculated regression equationand R2 were Y = 0.868X + 1.384 and 0.71, respectively, where Y is simulated and X is theobserved final shrimp weight. The Average Relative Error (ARE) was 5.64%. Forvalidation comparing experimental and simulated final shrimp weight, we found Y =1.091X + 0.116, R2 = 0.97 with an ARE of 10.22%.The model can predict general patterns of shrimp growth. The explanatory character of themodel allowed prediction of growth under a wide range of conditions. Effect of feednutritional quality, feeding rate, body composition, and temperature and moulting onshrimp can be predicted well by the model, which will provide insight of interactionsamong the growth and growth parameters of shrimp.
