Habitat and Ecology [top]

Habitat and Ecology:Notopogon macrosolen is a deep-water, bathydemersal species that prefers soft bottoms of mud or sand at 200-500 m depth (Heemstra 1986). The record length of this fish was measured at 33 cm (Heemstra 1986). Little else is known about the reproductive patterns, fecundity, recruitment, diets or life history of this species.

Movement patterns:Unknown

Use and Trade [top]

Use and Trade: This species has not been recorded in trade.

Threats [top]

Major Threat(s): Notopogon macrosolen is occasionally taken as by-catch in trawls off southern Namibia (Bianchi et al. 1999). There are no catch data available for this species. However due to the depths at which this species is found, the incidental catch of this species is unlikely to pose a significant threat to the population.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Notopogon macrosolen. It is not listed in any international legislation or trade regulations, and it does not occur in any protected areas.
