Pomadasys incisus is a fast growing species, that is widespread and at least very abundant in some parts of it range, particularly over rocky bottoms, and therefore considered Least Concern. However, it is considered overexploited, primarily as bycatch in the Canaries and Aegean and possibly overexploited elsewhere in trawl fisheries and therefore its population levels need to be closely monitored.

Population [top]

Population:Pomadasys incisus has been observed in relatviely high-density schools in the coastal waters of the Canarian Archipelago, and is considered to be among the 20 most abundant demersal species in the area (Pajuelo et al. 2003). Listed as one of the 5 most abundant fish species in underwater surveys of mostly rocky areas across the Canaries with the highest count of any species on one of the transects (Hajagos and Van Tassell (2001). This is a fast-growing short-lived species (Pajuelo et al 2003). A survey of the fisheries of the Canary Islands found that this species was in danger of recruitment-overfishing, as 45% of the individuals caught are below the breeding size (Pajuelo et al. 2003). In the Canary Islands an 80% reduction in non-exploited equilibrium rates are inferred from a growth-overfishing model. This rate of exploitation is difficult to interpret because exploited rates of decline are unknown in this type of soft-sediment trawling. Furthermore, this species is abundant over rocky bottoms in the Canary Islands at the same time as growth overfishing is reported. Abundant in parts of its range in the Mediterranean (Francour et al. Med Red List workshop assessment 2007). Kapiris et al (2008) indicate from anecdotal information from fishermen that this species is heavily exploited as by-catch in the Aegean sea. It is a thermophilic species that apparently is expanding its range into the northern Med because of increasing temperatures (Fehri-Bedoui and Gharbi 2008). This species is also caught in Angolan fisheries, though not at such high levels (Agostinho et al. 2005).
Current Population Trend:Unknown

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Pomadasys incisus is a demersal species, found over sandy/ muddy and rocky bottoms mostly at a depth range of 10 to 50 m but recorded down to 100 m (Kent citation). It is found inshore in estuaries (Kapiris et al. 2008), harbours, to a couple of miles offshore. It feeds on near-bottom invertebrates. Pomadasys incisus is a non-seasonal spawner and breeding occurs year round; maturity is reached in approximately 2 years (Pajuelo et al. 2003).
Generation Length (years):5

Use and Trade [top]

Use and Trade: Although caught as by-catch, presumed consumed in parts of its range at least in western Africa.

Threats [top]

Major Threat(s): Pomadasys incisus has no current commercial value, but is taken as by-catch in trawl fisheries in the Aegean Sea and Canary Islands (Fehri-Bedoui and Gharbi 2008) and presumably also taken as by-catch in trawl fisheries throughout its range. Some landing reported in FAO statistics for the 1980s and 1990s indicate some commercial utilization. Most reports suggest that it is discarded, although it is retained and consumed in parts of its range. In Tunisia, it is caught by artisanal gears such as trammel and gill nets, beach and purse seines, long lines and trawls (Fehri-Bedoui and Gharbi 2008).

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species, however in places its distribution may coincide with marine protected areas. Further research and monitoring of the population and harvest levels of this species should be carried out. Conservation measures need to focus on minimising the by-catch of this species to prevent this species becoming threatened.
