Infestation of Lithodes santolla (Decapoda: Lithodidae) by Pseudione tuberculata (Isopoda: Bopyridae) in San Jorge Gulf, Southwestern Atlantic Ocean

Abstract: The bopyrid isopod Pseudione tuberculata infests decapod crustacean species of family Lithodidae. It has previously been found in Neolithodes diomedeae from Chile, and in Lithodes santolla and Paralomis granulosa from the Beagle Channel. A case was detected in 1980 in San Jorge Gulf, and since then no bopyrid has been found in any of the 12,300 specimens of Lithodes santolla obtained from commercial captures. In the present study we collected and analyzed 648 juveniles of Lithodes santolla measuring between 8.… Show more

“…Parasitic isopods impact a variety of commercially important hosts, including brachyuran crabs, false kings crabs, king crabs, and shrimp (e.g., [56] , [57] , [58] , [59] , [60] ) or are prey for commercially important species (e.g., [61] ). Although bopyrids do not pose a medical threat to humans, their presence in the branchial chamber of hosts can negatively impact salability of infected hosts such as shrimp [62] .…”

“…Kuris & Lafferty (1992) examined the impact of infestations on crustaceans that are recruited in closed systems like fjords, and verified an increased possibility of massive infestations (see also Shields, 2012). Previous works conducted in the study area on the prevalence of the isopod P. tuberculata on L. santolla were characterized by low spatial coverage, mostly centering sampling on Beagle Channel and San Jorge Gulf in Argentina (Roccatagliata & Lovrich, 1999;Miranda-Vargas & Roccatagliatta, 2004;Vinuesa & Balzi, 2010) and an isolated location in the Magellan Strait in Chile (Cañete et al, 2008). To the best of our knowledge, our work is the first to analyze southern king crab recruitment to fishing grounds at the spatial scale of ca.…”

“…For southernmost Chile and Argentina Pseudione tuberculata has been found parasitizing the lithodid crabs L. santolla and Paralomis granulosa (Lovrich, 1991;Roccatagliata & Lovrich, 1999;Cañete et al, 2008;Vinuesa & Balzi, 2010). However, these studies did not consider simultaneous latitudinal variations of infestation (i.e., spatial mesoscale; ~700 km) or else they simply described such variability using samples collected exclusively in processing plants.…”

“…En otras especies de anomuros estudiadas la prevalencia de los bopíridos decrece con la talla y los valores más altos de prevalencia se registran en estadios juveniles tempranos del hospedador (Roccatagliata y Lovrich 1999, González y Acuña 2004, Vinuesa y Balzi 2010. La reducción de la prevalencia en estas especies puede ser consecuencia de la remoción del parásito en las sucesivas mudas o a una alta mortalidad inducida por el bopírido.…”

“…galacanthae implica una mayor demanda de energía y un costo adicional para el hospedador que puede conducir a la muerte de éste y explicar la prevalencia menor en los estadios posteriores. La estabilización de la prevalencia en langostillas con LC > 10 mm indica una baja mortalidad inducida por el parasitismo La presencia de estadios inmaduros del parásito en estadios juveniles del hospedador fue considerada evidencia de una infestación temprana (Roccatagliata y Lovrich 1999, Vinuesa y Balzi 2010. La ocurrencia de hembras inmaduras y larvas criptoniscus del parásito en ejemplares del intervalo 7-9,99 mm de LC sugiere que la infestación comienza en este rango de tallas.…”
