The Atlantic Needlefish, Strongylura marina, has been assessed as Least Concern. This broadly distributed species is harvested as a food source, however it is not a highly desired food fish and so is not of commercial importance. It is likely to be taken as by-catch by other fisheries operating within its range, although this is likely to be a localised threat only. This species is unlikely to be impacted by habitat degradation as it is known from a broad range of habitats. Further research is needed on the biology of this species to determine its vulnerability to fishing pressure.

Habitat and Ecology [top]

Habitat and Ecology:The Atlantic Needlefish, Strongylura marina, is found on reefs in subtropical climates, mangrove lined lagoons and seagrass beds. It is also known to enter freshwaters. Adults and juvenilles are mainly piscovorous, with shrimp being an important food component in the rainy season (Arceo-Carranza et al. 2004). Eggs attach to items in the waters by surface tendrils. The depth range if this fish is unknown.
Systems:Freshwater; Marine

Use and Trade [top]

Use and Trade: Fishing only occurs where this species attains a large size (Arceo-Carranza 2004).

Threats [top]

Major Threat(s): The Atlantic Needlefish is commercially harvested, but consumption is restricted to local areas where this species attains a large size (Arceo-Carranza et al. 2004). This species is mainly caught as a bait source for marlin sport fishing. It is caught by casting or trolling surface or near-surface lures, seines, trammel nets, and by using light as a lure. This species is not of significant commercial importance as the green bones are not considered favourable.

Due to the coastal nature and large size of this species, it is likely to be taken as by-catch by coastal fisheries operating within its range. However, this is not considered to be a major threat to this species as this threat is not known throughout its entire range. There is no evidence to suggest that this species is undergoing a significant population decline.

Conservation Actions [top]

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

Further research on the biology of this species is needed.
