Ecología de postlarvas de camarón azul (Litopenaeus stylirostris) y camarón café (Farfantepenaeus californiensis) en el Estuario del Río Colorado Ramírez-Rojo, RA Aragón-Noriega, EA postlarvae shrimp Colorado River Litopenaeus stylirostris Farfantepenaeus californiensis postlarvas camarón Río Colorado Litopenaeus stylirostris Farfantepenaeus californiensis The study describes habitat use by penaeid shrimp larvae that enter the Colorado River Delta. A location was chosen in the Santa Clara Channel in the core zone of the Upper Gulf of California and Colorado River Delta Biosphere Reserve, where collections were done during three consecutive days of each spring tide from May to October 2000. A 505-µm net was anchored and left in the water for 10 minutes when the height of the tide was 1 m above the level of the channel, during both flood tide and ebb tide. Blue shrimp (Litopenaeus stylirostris) and brown shrimp (Farfantepenaeus californiensis) postlarvae were caught in proportions of 80% and 20%, respectively. The postlarval abundance of blue shrimp was significatively greater during flood tide than during ebb tide in May, June and September, but significatively greater during ebb tide than during flood tide in July and August. The blue shrimp postlarval sizes were significatively greater during ebb tide than during flood tide. No differences in the abundance of brown shrimp postlarvae were found between flood and ebb tides. It is concluded that the Colorado River Delta is a breeding area for blue shrimp, but not for brown shrimp. Se describe el uso del hábitat por las postlarvas de camarones peneidos que ingresan al delta del Río Colorado. Se seleccionó una localidad en el Canal Santa Clara, dentro de la zona núcleo de la Reserva de la Biosfera Alto Golfo de California y Delta del Río Colorado, donde se realizaron recolecciones durante tres días consecutivos de cada marea viva de mayo a octubre de 2000. Se ancló una red con luz de malla de 505 µm que se mantuvo en el agua 10 minutos cuando la altura de marea se encontraba a 1 m sobre el nivel del canal, tanto en el flujo como en reflujo. Se capturaron postlarvas de camarón azul Litopenaeus stylirostris y camarón café Farfantepenaeus californiensis con proporciones de 80% y 20%, respectivamente. La abundancia de postlarvas de camarón azul fue significativamente mayor en el flujo que en reflujo en mayo, junio y septiembre, pero significativamente mayor en el reflujo que en el flujo en julio y agosto. Las tallas de las postlarvas de camarón azul fueron significativamente mayores en el reflujo que en el flujo. En las postlarvas de camarón café no se encontró diferencia entre la abundancia del flujo y el reflujo. Se concluye que el delta del Río Colorado, es un área de crianza sólo de camarón azul y no para camarón café.
