Importance/Issues

Small-toothed sawfish (Pristis pectinata) is a federally listed endangered species found in EVER and BISC, typically near and in estuaries, bays, and inlets utilizing seagrass, mud/sand bottom, oyster bars, reefs, and mangroves. This long-lived and large species (record is 18 ft. long) was formerly a fishery before stocks dwindled. Its saw makes it susceptible to entanglement in nets and lines. Little is known about this species, but, like other rays and sharks, it has limited reproductive potential.

Monitoring Objectives

What are the status and trends in distribution, relative abundance, number of active nursery areas, and demographics (sex ratios, adult/juvenile ratios)

Approach

At this time there is no targeted small-toothed sawfish population monitoring program that SFCN is aware of, although MOTE Marine Laboratory conducted an extensive research project. However there is a Sawfish Encounter Reporting program maintained by the Florida Museum of Natural History. This program is used to track locations of sightings and consequently estimate the current distribution of the small-toothed sawfish compared with historical encounter data.

Monitoring by SFCN is deferred due to insufficient funding.
