- Distribution of microplankton and fish larvae related to sharp clines in a Patagonian fjord Mauricio F. Landaeta Rodrigo A. Martínez Claudia A. Bustos Leonardo R. Castro Ciencias de la Tierra Sprattus fuegensis Maurolicus parvipinnis Vertical stratification Vertical distribution of microzooplankton and fish larvae was studied in a Patagonian fjord from Chile. Zooplankton collection, including larvae of the sprat Sprattus fuegensis (Clupeidae) and the lightfish Maurolicus parvipinnis (Sternoptychidae) were collected during a 25 h period inside Steffen fjord (47°S) during November 2008, using stratified sampling of zooplankton, prey field, and CTD casts. Most copepod nauplii, copepodites of Acartia tonsa and large M. parvipinnis larvae were collected in the vicinity of the pycnocline, while larval S. fuegensis did not show a spatial pattern. Therefore, some larval fish species may utilize stable water parcels to increase predator-prey encounter rates. 2013 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47928716020 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.48
