He also published on molluscs Iconographie conchyliologique, 1828.Marine painting was another of his occupations and a Roux family concern.
Roux was a correspondent of Risso who in 1826 named the copepod Pandarus rouxi after him.
In 1831 he joined Charles von HĂĽgel, who was travelling for the Austrian government, on an excursion to Egypt and from there in 1832 to Bombay, where he later died of plague.

It is also likely that the specific name of the longstriped blenny (Parablennius rouxi) honours Roux.
