Sustainability rating five info

Sustainability overview

Guitarfish are listed by IUCN as Endangered. Its biology and inshore habitat make it highly susceptible to population depletion. Because of this, they are automatically a red-rated species.

Biology

Guitarfish tails look like those of a typical shark but their head is often triangular or a guitar-like shape. Guitarfish inhabit sandy and muddy bottoms, from the intertidal zone to about 100 m. Sometimes near rocky reefs. They are usually seen slow swimming over bottom or partially buried. It feeds on benthic invertebrates and fishes. Guitarfish are ovoviviparous, one or two litters per year with 4-10 embryos. The age at maturity is not known for either sex, nor the longevity of this species.

Stock information

Guitarfish are listed by IUCN as Endangered (2016) due to widespread and unregulated fishing throughout it’s range. Guitarfish populations are expected to be declining and are possibly extinct in Balearic isles. Their biology and inshore habitat make it highly susceptible to population depletion.

Due to very low populations, Guitarfish are automatically red-rated.

Management

There are a lack of management measures for Guitarfish, however, in October 2017, the Mediterranean population of the Common Guitarfish were listed as an Appendix I species under the Bonn Convention. Appendix I is the highest level of protection (and has been provided to other species such as the Whale Shark). Common Guitarfish cannot be caught and retained. The IUCN has recommended that the Mediterranean needs to designate and research critical coral reef habitat for Guitarfish (particularly when impacted by trawling), monitor Guitarfish catches and record any landings for the species.

Capture Information

Guitarfish populations undergo high exploitation rates. They are an easy target for artisanal fisheries and are likely taken as bycatch in commercial fisheries of all kinds including prawn and bottom trawl fisheries.
