Feeding strategy of early juvenile stages of the southern king crab Lithodes santolla in the San Jorge Gulf, Argentina

Abstract: Resumen.-Se analizó el contenido estomacal de 313 ejemplares juveniles de centolla de ambos sexos con longitudes de caparazón (CL) entre 8,40 y 49,04 mm, estudiándose la influencia del sexo, talla, estado de muda y estación del año. Los animales fueron capturados mediante buceo en muestreos estacionales en el infralitoral rocoso del área central del Golfo San Jorge. Se determinó la frecuencia de ocurrencia (FO) y abundancia relativa (AR) de las presas halladas, estado de repleción y peso del contenido estomaca… Show more

“…Sea water temperature usually varies between 7 and 168C and salinity is ,33.5 psu (Vinuesa et al 2013). Extensive kelp forests of Macrocystis pyrifera occur in the sampling area, with a low incidence of the recently introduced U. pinnatifida (Zaixso et al, in press).…”

“…Extensive kelp forests of Macrocystis pyrifera occur in the sampling area, with a low incidence of the recently introduced U. pinnatifida (Zaixso et al, in press). The complex biogenic structure of kelp forests and other biogenic habitats, as the ribbed mussel beds, provides important structural features, food and available space for settlement and recruitment to many species of invertebrates (Vinuesa et al 2013). A. dufresnii occurs at low densities, ranging from 0.3 to 0.6 individuals m À2 (D. G. Gil, unpubl.…”

“…Despite the economic and ecological importance of the southern king crab Lithodes santolla (Molina, 1782) as the most important decapod crab for fishery in Chilean/Argentinian Patagonia (Lovrich, 1997;Vinuesa et al 2013), investigation of potential plastic ingestion and their negative impacts on marine biota in the Subantarctic Magellan region is unknown.…”

“…Estudos em espécies de Lithodes, Paralithodes e Paralomis tem demonstrado o consumo de um amplo espectro de itens alimentares, entre os que se mencionam: algas, briozoos, hidrozoos, foraminíferos, equinodermos, poliquetos, moluscos, crustáceos e peixes (Comoglio & Amin 1999, Vinuesa et al 2013. No entanto, durante as fases zoeas os Lithodidae se alimentam principalmente de microalgas.…”

“…Dessa forma a dieta dos Lithodidae começa aumentar progressivamente, indivíduos juvenis são essencialmente onívoros e macrófagos, com uma média de dez presas consumidas, entre fitoplâncton, protistas e invertebrados (Bright 1967). Enquanto que indivíduos adultos são predadores majoritariamente carnívoros com uma composição alimentar de cerca de 20 grupos (Tarverdieva & Zgurovsky 1985, Comoglio et al 1990, Balzi 1997, Vinuesa et al 2013.…”
