This species was previously assessed as Endangered in 1996 under vers 2.3 criteria (1994), it is now known to be relatively widespread on the Atlantic coast of South America and Brazil. There is currently little evidence of population declines from fishing. It can be very common in Brazil which corresponds to at least 50% of its range and it is not heavily fished. Export prohibition is in place in Brazil for the ornamental trade. It is listed as Least Concern. The species is associated with hardbottom habitats and could incur local impacts in the event of loss of hardbottom or associated coral habitats.

Population [top]

Population:This species is common in parts of its range. For example, it is very common in northeastern and eastern Brazilian coastal reefs (Dias 2007, Chaves et al. 2010, L.A. Rocha pers. comm. 2015) and in the Espirito Santo State. This species has shown significant differences in abundance at two reef sampling locations in Brazil (5% frequency/0.6% abundance) on a reef visited frequently by recreational boaters and tourists; (18.33% frequency/1.34% abundance) in a reef not frequently visited by recreational boaters and tourists (Medeiros et al. 2007). It is rare and appears only in spotty localities where it ranges outside Brazil in the southern Caribbean (J. Tavera and A. Acero pers. comm. 2015).
Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:This species is typically found in association with hardbottom reef habitats. Although this species has been thought to avoid blue-water insular conditions, with a preference for turbid waters, recent observations have shown this species to remain in environments that experience seasonal fluctuations in turbidity due to rain (Dias 2007). This species has been observed in tropical coastal rock reef tidepools (Cunha et al. 2008). This species is often solitary and nocturnal, frequenting reef crevices during daylight. However, it also exhibits diurnal and gregarious habits, mixing with other haemulid species or schooling with conspecifics (Nunes and Sampaio 2006). Gut content analysis from one individual revealed the digested remains of crabs, filamentous algae, gastropod shells and polychaete worms (Acero and Garzon 1982).

Use and Trade [top]

Use and Trade: In some coastal areas of Brazil, this species is used as food by small-scale fishers and it is caught by spearfishing, net fishing, and hook and line (Dias 2007). This species does not appear to be a main target, neither for commercial or artisanal fisheries in the states of Bahia and Paraiba, Brazil (Nunes and Sampaio 2006). This species is not highly commercially exploited in northeastern Brazil (Nunes and Sampaio 2006, Dias 2007). The species has been cited as experiencing substantial fishing pressure in the Guarapari Islands, Brazil (Floeter et al. 2006), but there is little empirical evidence of this pressure (L. Rocha pers. comm. 2011). It is a minor component of the aquarium trade (Gasparini et al. 2005).

Threats [top]

Major Threat(s): Anisotremus moricandi is of relatively minor commercial importance and is rarely targeted. There are no major threats from fisheries. Populations can be impacted by human activities in coastal areas, both on reefs and in tidepool habitats (Dias 2007). Unregulated recreational boating and tourist activity on reefs has been shown to negatively affect abundance of this species on reefs (Medeiros et al. 2007). High sedimentation rates coming from land discharges of pollutants that reach coastal reefs may also negatively affect this species (Hodgson 1999). Additionally, tidepools may be impacted by development in the coastal zone (Cunha et al. 2008).

Conservation Actions [top]

Conservation Actions: It has been suggested that strategies to conserve A. moricandi populations in NE Brazil should place strong emphasis on the conservation of their habitats, especially the biogenic coastal reefs (Nunes and Sampaio 2006, Dias 2007). In Brazil, this species is not included in the list of species that can be exported, protecting this species from ornamental trade exploitation. Since the listing, there has been been an increase in the number of  Brazilian reef fish studies over the past decade, many of which have cited this and other endangered Brazilian species as reasons to establish and monitor Marine Protected Areas (Chaves et al. 2010).
