Psammobatis normani is a small, poorly known sandskate from off Argentina (in depths of 70 to 145 m) and around Guafo Island, Chile (in depths of 70 to 358 m). Probably more widely distributed in Chile than presently known. Its maximum reported size is 53.7 cm total length (TL) and nothing is known of its biology. It is taken as bycatch in the bottom trawl fisheries for kingclip fish Genypterus blacodes and hake Merluccius australis, but catch data is not available. Like many other South American skate species, further research is required to ascertain its distribution, biology and interactions with fisheries.

Habitat and Ecology [top]

Habitat and Ecology:Psammobatis normani is recorded from the continental shelf of Argentina (70 to 145 m) and the shelf and slope of Chile (70 to 358 m). McEachran (1983) described 36 specimens (25 males, 29.6 to 53.7 cm total length (TL); 11 females, 29.5 to 41.2 cm TL) from Argentina. In Chile, six specimens (all males) were captured by bottom trawl off Guafo Island at depths of 70 to 358 m (Lamilla 1993). These are the only records of this species in the literature.

Threats [top]

Major Threat(s): Bycatch in the bottom trawl fisheries for kingclip fish Genypterus blacodes and hake Merluccius australis. In a bottom trawl fishery cruise off Guafo Island, Chile, approximately 10% of total skates captured were Psammobatis species (P. normani, P. rudis and P. scobina). These were all discarded (Lamilla, unpubl. data).
