Title A name given to the resource Distribución del ictioplancton en la Patagonia austral de Chile: potenciales efectos del deshielo de Campos de Hielo Sur Ichthyoplankton distribution in South Patagonia, Chile: potential effects of ice melting from the Southern Ice Field Creator An entity primarily responsible for making the resource Mauricio F Landaeta, Claudia A Bustos, Pamela Palacios-Fuentes, Pablo Rojas, Fernando Balbontín Description An account of the resource Durante octubre-noviembre de 2009 se realizó un crucero oceanográfico entre 50 y 53°S de Chile austral, en las cercanías del glaciar Campos de Hielo Sur. Las estaciones cercanas al glaciar presentaron baja temperatura (1-3°C) y salinidad (< 25), y alta estabilidad (frecuencia de Brunt-Väisälä N > 0,1 ciclos s-1). Los principales taxa del ictioplancton fueron huevos y larvas de sardina fueguina Sprattus fuegensis, pez hacha Maurolicus parvipinnis, Macrouridae y merluza austral Merluccius australis. El desove principal de S. fuegensis (~ 8000 huevos 10 m-2) ocurrió en zonas mezcladas de la plataforma continental adyacente, mientras que el desove de M. parvipinnis ocurrió en canales intermedios asociado a valores intermedios de estabilidad (N~0,06 ciclos s-1). Se observó una nula o baja abundancia de huevos y larvas de peces en las cercanías del glaciar, y la abundancia de huevos de M. parvipinnis estuvo relacionada positivamente con la temperatura y salinidad de la columna de agua y negativamente con la estabilidad de la columna de agua. Además, hubo una relación negativa entre la densidad del agua de mar y el diámetro de los huevos de S. fuegensis. La relación entre deshielo e ictioplancton podría tener consecuencias en el transporte advectivo y mortalidad masiva de huevos y larvas de peces y el acople pelágico-bentónico en la Patagonia austral de Chile. Como el cambio climático global ha incrementado los deshielos de glaciares en latitudes altas, y el aumento del ingreso de aguas de baja temperatura y salinidad podría tener consecuencias en el ictioplancton de la Patagonia chilena.In October-November 2009, an oceanographic survey was carried out between 50 and 53°S off southern Chile, near the Southern Ice Field. The stations near the glacier showed low temperatures (1-3°C) and salinity (< 25), and high stability (Brunt-Väisälä frequency N > 0.1 cycles s-1). Main ichthyoplankton taxa were eggs and larvae of southern sprat Sprattus fuegensis, lightfish Maurolicus parvipinnis, Macrouridae, and southern hake Merluccius australis. The main spawning area of S. fuegensis (~8000 eggs 10 m-2) occurred in mixed zones of the adjacent continental shelf, whereas the spawning of M. parvipinnis occurred in intermediate channels associated with medium stability values (N~0.06 cycles s-1). Fish egg and larval abundances were null or scarce near the glacier, and the abundance of M. parvipinnis eggs was positively related to the temperature and salinity of the water column, and negatively related to water column stability. Moreover, a negative relationship was observed between seawater density and the diameter of S. fuegensis eggs. The relation between ice melting and ichthyoplankton may have consequences for advective transport and mass mortality of fish eggs and larvae, as well as pelagic-benthic coupling in the Chilean South Patagonia. Global climate change has increased glacier ice melting at high latitudes, and the increased entry of colder, less saline waters in coastal areas may have consequences for the ichthyoplankton in the Chilean Patagonia.
