The study was conducted from March 1999 to November 2002 in a suspended culture located in Bahía Juncalito, Gulf of California, Mexico. Nodipecten subnodosus (Sowerby, 1835) is a species with fast growth (ø=3.91) and alometric, with a seasonality of 0.78 and an amplitude of 0.8. Its growth was described by the von Bertalanffy model. An average growth rate of 4 mm/month was estimated for the first 16 months of the study. Then, it decreased to 1.3 mm/month until the end of the experiment. The survival was high (? 89 %) and did not change substantially until November 2001 when it decrease to 40%. In Bahía Juncalito, N. subnodosus attain its first spawn at nearly 2-years old with a mean shell height of 72 mm.
