|Taxonomic Notes:||Last and Stevens (1994) considered the Reticulated Swellshark (Cephaloscyllium fasciatum) to also occur off northwestern Australia, however, that species is distinct and has now been described as Cephaloscyllium hiscosellum by White and Ebert (2008).|

The Reticulated Swellshark (Cephaloscyllium fasciatum) was originally assessed globally as Data Deficient in 2003 when the species was also thought to occur off northwestern Australia. The Australian form is distinct and has recently been described as Cephaloscyllium hiscosellum White & Ebert, 2008; it is treated in a separate assessment. This assessment of C. fasciatum replaces the 2003 assessment for that species, although the category of Data Deficient remains appropriate.
The Reticulated Swellshark is a small (to 42 cm total length), poorly known deepwater catshark which has a patchy occurrence in the western Pacific around Viet Nam and China (Hainan Island), and probably also the Philippines. This species occurs on the outermost continental shelf and upper slope at depths of 219–450 m. Its biology is very poorly known. This species is considered to be Data Deficient, with no information on its population status, and although it is a known component of demersal trawl bycatch, no details are available.
The Reticulated Swellshark has a patchy occurrence in the western Pacific around Viet Nam and China (Hainan Island), and probably also the Philippines (Compagno et al. 2005, Schaaf-da Silva and Ebert 2008). References to the species off northwestern Australia are attributable to C. hiscosellum White & Ebert, 2008.

There is no population information on the Reticulated Swellshark.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||
The Reticulated Swellshark, a tropical catshark, is found on muddy substrates on or near the bottom on the outer continental shelf and uppermost slope, at depths of 219–450 m (Compagno et al. 2005, Schaaf-da Silva and Ebert 2008). Oviparous; the hatchlings are ~12 cm total length (TL). Maximum size at least 42 cm TL (adolescent or adult female); size at maturity ~36 cm TL (males) (Compagno et al. 2005, Schaaf-da Silva and Ebert 2008). Biology is very poorly known.
|Use and Trade:||
Use and trade of the Reticulated Swellshark are poorly known.
The Reticulated Swellshark is of minor interest to fisheries where it is caught by commercial demersal trawlers as bycatch and possibly utilized for fishmeal in Asia. Actual level of exploitation is unknown.
There are no conservation actions in place for the Reticulated Swellshark. The level of exploitation requires examination. It is suggested that species-specific landings are reported and monitored where possible.
