Description The Bengal Guitarfish (Rhinobatos annandalei) is a small (to 95 cm total length) guitarfish that occurs in
the northern Indian Ocean from the United Arab Emirates (UAE) to Bangladesh, including Sri Lanka. The
western boundary of this species distribution is uncertain due to confusion with the Spotted Guitarfish
(R. punctifer). It is demersal on the inner continental shelf at depths of 5–73 m. The species is mainly a
bycatch of a range of industrial and artisanal gears including demersal trawls, longlines, and gillnets. The
meat is consumed locally and traded internationally, and the skins are exported from Bangladesh to
Myanmar to be made into accessories (e.g. handbags). There is a high level of fisheries resource use and
increasing fishing pressure across the range of this species. Severe population reduction is inferred from
actual levels of exploitation, as well as several historical accounts and contemporary datasets from the
UAE, Iran, Pakistan, and India. Landings data of guitarfishes and rays from the UAE, Iran, Pakistan, India,
and Bangladesh indicate landings declines of 69–93% consistent with population reductions of 80% over
the past three generation lengths (27 years). These levels of declines are not species-specific but are
informative for understanding the broader levels of guitarfish decline in the region. It is suspected that
the Bengal Guitarfish has undergone a population reduction of >80% over the past three generation
lengths (27 years) due to actual levels of exploitation, and it is assessed as Critically Endangered A2d.
