Habitat and Ecology
It inhabits rocky reefs of island shores and offshore reefs and shallow banks in depths from 20-100 m. It prefers areas of high bottom relief and strong hydrodynamic conditions.
It feeds mainly on macro invertebrates (sea urchins, gastropods, etc.). It is a sequential protogynous hermaphrodite (all males result from sex-changing females at 45-65 cm TL). It shows marked haremic territorial system, typically one male to two to three females (P. Afonso pers. comm. 2008). Supposedly a pelagic spawner, it does not build a nest or provide any parental care. Juveniles occur isolated below 30 m, sheltering within reef crevices and holes.
From 20 to 200 meters.

Red List Criteria
In the Azores it is common on rocky reefs from 15-50 m depth all across the archipelago and offshore shallow banks with suitable habitat, but naturally occurs in scarce numbers , especially in the northernmost islands (Afonso 2002).
In Madeira (Ribeiro et al. 2005, Ribeiro et al. 2006) and the Canaries (Falcón et al. 1996) populations are less numerous, or even absent locally, although in the recent past they have supported local multispecies fisheries. The very limited information available also points to the rarity of this species in the Cape Verdes (Monteiro et al. 2008), its southern distribution limit (P. Afonso pers. comm. 2008).
In the Canary Islands it was recently considered commercially threatened due to overexploitation, mostly in the 1990s (Brito and Morales 1998). In Madeira it is rare or absent, most probably due to overfishing and habitat degradation of the coastal communities in past decades. In the Azores, numbers have been reduced in fished areas in recent years, particularly those of larger (male) individuals (Afonso 2002, Afonso et al. 2006).
Relevance to Humans and Ecosystems
The barred hogfish, Bodianus scrofa, is a species of wrasse native to the eastern Atlantic Ocean, where it occurs around the various island groups from the Azores to Cape Verde. This species occurs on rocky reefs at depths of 20 to 200 m (66 to 660 ft). It can reach a length of 43 cm (17 in), though most do not exceed 30 cm (12 in). It is of minor importance to local commercial fisheries.
