The Cabinza Grunt, Isacia conceptionis, has been assessed as Least Concern. Despite this species been commercially fished, it apparently remains abundant throughout its range and there is no indication it is undergoing severe population declines at present. Monitoring of the harvest levels of this species is needed to ensure harvesting and climatic events such as El Nino do not cause future declines..

Geographic Range [top]

Population [top]

Population:The Cabinza Grunt has been described as among the most abundant species in this region, both currently and historically (Reitz 2001; Sielfeld et al. 2002; Vildo et al. 1999). Angel and Ojeda (2001) found Cabinza Grunt to be the most abundant fish species along the northern Chilean coast. It is thought that, like other species in the region, it suffered population declines during El Nino events (Sielfeld et al. 2002).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The Cabinza Grunt occurs over rocky and sandy bottoms and has a depth range of 0-50 m. This species is dominant in shallow rocky subtidal areas (Angel and Ojeda 2001). Its diet consists of small crustaceans, polychaetes and algae.

Use and Trade [top]

Use and Trade: The Cabinza Grunt is harvested commercially as a food source.

Threats [top]

Major Threat(s): The Cabinza Grunt is harvested commercially as a food source. Landings in the Humboldt Current have ranged from between 1,000 to near 7,000 tonnes over the last ten years: 1995 - 3,282.34 tonnes, 1996 - 2,362.11 tonnes, 1997 - 1,701.67 tonnes, 1998 - 2,545.16 tonnes, 1999 -  6,119.10 tonnes, 2000 - 3,361.92 tonnes, 2001 - 3,244.06 tonnes, 2002 - 3,842.05 tonnes, 2003 - 2,882.75 tonnes, 2004 - 3,158.12 tonnes. While there are annual fluctuations in the landings of this species, there is no obvious decline assuming the catch per unit effort has remained relatively constant. Fluctuations in the landings of this species might be attributed to El Nino events.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Isacia conceptionis, however its distribution coincides with a number of marine protected areas.

Monitoring of the harvest levels of this species is needed.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
