Commercial culture of marine shrimp Litopenaeus vannamei were done in Rio Grande do Norte state from 08/08/2002 to 10/15/2005. Were used statistical models to correlate the production variables (production, productivity, survival rate, feed convection ratio, final mean weight and offered feed quantity) with the management and water quality ones (number of ponds, number of cycles, recirculation system, season of the year, days of culture, stocking density, postlarvae source, ration brand, oxygen, temperature, pH and transparency). It was used the stepwise method associated to Box and Cox transformer to select the variables more significatives in each model. It was verified that the management variables with more correlation were ration brands, hatchery of postlarvae source and days of culture.
