Abstract
Tracing the occurrence of the Critically Endangered smalltooth sawfish Pristis pectinata at its southernmost distribution in the Southwest Atlantic Ocean
Highlights
Sawfishes are among the largest marine and euryhaline fishes
Interviews with Uruguayan artisanal fishermen resulted in 3 oral reports of Pristis pectinata (Table 2); their fishing experience ranged from 25 to 45 yr
Interviews with Argentinian artisanal fishermen yielded no records of P. pectinata; these fishermen’s fishing experience ranged from 7 to 73 yr (23.8 ± 15.7 yr)
Summary
Endang Species Res 38: 1–9, 2019 bly Extinct (Dulvy et al 2016). These population depletions have made sawfishes the most threatened group of chondrichthyans (Dulvy et al 2014, Fernandez-Carvalho et al 2014). According to the International Union for the Conservation of Nature’s (IUCN) Red List of Threatened Species, 3 sawfish species (Pristis pristis, P. pectinata, and P. zijsron) are currently classified as Critically Endangered (Carlson et al 2013, Kyne et al 2013a, Simpfendorfer 2013). All 5 species are listed in Appendix I of the Convention on International Trade of Endangered Species (CITES) (Carlson et al 2013). The smalltooth sawfish P. pectinata has been listed under the US Endangered Species Act since 2003 by the US National Marine Fisheries Service (NMFS 2003)
