The purpose was to study the individual growth of two shrimp´ species of Penaeidae family who are subject to fishing and farming; the white shrimp Litopenaeus vannamei and blue shrimp L. stylirostris. The hypothesis was that both species would have an asymptotic growth type with sigmoid shape. The data come from shrimp farming in earthen ponds of an aquaculture farm located in the Gulf of California. Stocking density was 25 post larvae m-2 in ponds of 1.8 ha. Three asymptotic models were applied to length at age data: von Bertalanffy, Gompertz and logistic. Best model was selected according to the Akaike information criterion. The final size of white shrimp was 128.8 mm in 140 rearing days. The estimated asymptotic length was 130 mm. Blue shrimp final size to harvest was 142.2 mm 158 in days and the asymptotic length was 174 mm. For both species model which better described the growth was the logistics, consequently the conclusion was that the growth of both species must be sigmoid shape with inflection point at 50% of the curve (symmetrical).
