This study would not have been possible without the collaboration of J. Peiro-López and L. Muñoz-Padilla of Acuacultura Mar/Acua Técnia. J. López-Rocha and O. Armendáriz-Ruíz prepared the drawings and figures. C. Cooksey and D. Voltolina provided valuable comments. This study was supported by grants from the CGPI, COFAA, and EDI programs of the Instituto Politécnico Nacional.

N2 - The consumption of electricity and propane for producing larvae and postlarvae of the whiteleg shrimp (Litopenaeus vannamei) was examined in a commercial shrimp hatchery on the Baja California Peninsula of Mexico. Between January and August 2005, 6 × 106 postlarvae (average age PL16) were produced from 1.43 × 109 nauplii. During that production period, the hatchery used 2.48 × 109 kcal of fossil fuel energy (30% for electricity, 70% for liquid propane), which was equivalent to 16% of the operating costs. Electricity was used mainly for larval and postlarval rearing (36% and 10%) and microalgae culture (27%). During this production period, 1.47 × 109 kcal of propane were consumed for heating daily more than 600 m3 seawater daily. Of that total, 33% was used for broodstock maintenance, 65% for larvae culturing, and 2% for postlarvae rearing. With increasing costs for shipping postlarvae to the mainland Mexican coastal areas (15% of operating costs) and the need to remain competitive with hatcheries in the coastal areas of Sonora and Sinaloa, alternative energy sources to reduce overall operational costs in hatcheries of Baja California Sur are discussed.
