Sustainability overview

Guitarfish are listed by IUCN as Endangered. It's biology and inshore habitat make it highly susceptible to population depletion.

Biology

Guitarfish have a body form intermediate between those of sharks and rays. The tail has a typical shark-like form, but in many species the head has a triangular, or 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

Due to widespread and unregulated fishing throughout it's range the population is expected to be declining. The species are listed by IUCN as Endangered (2016). Species biology and inshore habitat make it highly susceptible to population depletion. Evidence of deline in all areas; possibly extinct in Balearic isles.

Management

The species is not subject to any management measures. There are some countries that implement marine protected areas or for example in Mauritania, there is a ban on elasmobranch fishing. However, otherwise, there is a lack of management for the species. The IUCN has recommended that the Mediterranean needs to designate and research critical coral reef habitat (particularly when impacted by trawling), monitor of species catches and populations and record any landings for the species.

Capture Information

The distribution of this species is fairly wide but it is subjected to fishing pressures throughout most of its range, as it is an easy target for artisanal fisheries and also likely taken as bycatch in commercial fisheries of all kinds including prawn and bottom trawl fisheries.
