- Dispersal patterns of shrimp larvae and postlarvae of the genus Solenocera Adolfo Gracia Mario A. Gómez Ciencias de la Tierra plankton Crustacea distribution seasonal abundance vertical migration The abundance and the dispersal processes during the larval and postlarval stages of Solenocera spp.(Burkenroad, 1939) is analyzed. Data were collected in three oceanographic cruises performed in the south of theCampeche Bay, Mexico, during summer and autumn 1993 and spring 1994. Summer was the period with the highestabundance with an average larval density of protozoea, mysis, and postlarvae of 19.8, 22.1, and 1.9 organisms per 100 m3 respectively. In general, larvae presented a typical daily migration pattern. They moved from deep areas to the surfaceat night, whereas during the day they tended to move downwards. Protozoeae were most frequently distributed atthe surface levels, whereas mysis were rather caught at deeper levels. In general, protozoea and mysis were distributed at depths above the thermocline, halocline and pycnocline. Food availability seems to be the most important factor determiningSolenocera spp. vertical distribution. 2007 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47942203 en http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.42
