This species is assessed as Data Deficient as there is no information available that provides estimates of population size, life history and ecology, and/or exploitation levels. More study is needed to accurately determine its taxonomic and conservation status. In addition, there is no evidence of any decline for this species and catch statistics are unavailable to our knowledge.
The previous assessment of this species was based on the 1994 IUCN Red List Categories and criteria version 2.3. This assessment was precautionary and designated S. robustus as Vulnerable (A2d) based, in part, on preliminary observations of the international trade of syngnathids for traditional medicines (Vincent 1996). Further research on the trade of pipefishes and pipehorses has, however, revealed that a limited number of pipefish and pipehorse species are involved in international trade (Martin-Smith et al. 2003, Martin-Smith and Vincent 2006). Reassessment of S. robustus using the 2001 IUCN Red List Categories and Criteria version 3.1, suggests that a designation of Data Deficient is more appropriate at this time, based on the dearth of available information regarding population size and structure. A listing of Data Deficient does not imply that the taxon is not threatened but that not enough information exists to quantify or even estimate extinction risk. Application of the category Data Deficient is a call for more research and scrutiny to be directed at this species.
The information available for S. robustus is limited to distribution and potential threats. The
taxon has been included in taxonomic overviews of syngnathids (Dawson 1985,
Paxton et al. 1989) and although
this species is not well represented in museum collections, it is apparently
fairly common in its depth range, at least in
Nothing is known about the biology of this species. Further research is necessary to accumulate information on the basic biological and population dynamics characteristics of this species (Pogonoski et al. 2002). Although it is likely that this species has specific habitat preferences that determine its abundance within its range, little or no research has focused on the critical habitat for this species (Pogonoski et al. 2002). Accurate distribution and depth data are needed to identify key habitats (Pogonoski et al. 2002).

Museum Records from Australian Fish Collections (Pogonoski et al. 2002): there are 25 specimens (standard length to 300 mm), trawled from a depth range of 55–68 m (many specimens do not have depths recorded), ranging in geographical distribution from Port Weyland (34°56’S, 137°05’E), SA westwards to Flinders Island (33°43’S, 134°31’E), SA. Specimens were collected between 1909 and 1982.
