ABSTRACT The Patagonian scallop (Zvgochlamys patagonica) fishery started in the Argentine Sea after exploratory cruises developed during 1995. Knowledge concerning the habitat requirements involved in the settlement processes of the target species was lacking. The main objectives of this study are to find Z. patagonica spat and to assess the characteristics and distribution of its primary settlement substrate (PSS). We observed under binocular microscope different invertebrate species (potential PSS) collected during 2006 from 125 sampling sites between 37[degrees] to 44[degrees]S and 83-133 m depth. Spat were found on the hydroid Symplectoscyphus subdichotomus (n = 215) ...
