Umbrina ronchus, the fusca drum, slender baardman, roncador, fusca croaker or slender tasselfish, is a species of croaker or drum from the family Sciaenidae which is found in the western Atlantic Ocean and the Mediterranean Sea.

Description

Umbrina ronchus has a rather elongate and moderately deep body. The small mouth is positioned inferiorly and contains the villiform teeth which are typical of the

anal fin which are black. They grow to 77 cm standard length, most are around 40 cm.[4]

Distribution

Umbrina ronchus occurs in the eastern Atlantic Ocean from the western Mediterranean Sea and the

Straits of Gibraltar south to the Western Cape and into the western Indian Ocean to the Persian Gulf. There are no current records from Namibia.[2]

Habitat and behaviour

Umbrina ronchus is found in inshore waters off sandy beaches and sheltering among rocks, from 20 to 200 m depth. The juveniles are mainly found in close to the shore, but unlike other sciaenids they are not normally found in estuaries.

benthic invertebrates.[1]

Fisheries

Umbrina ronchus is of minor commercial importance[1] and is normally sold fresh.[2]

Taxonomy

The habitat location for Umbrina ronchus is the Canary Islands and in one study, specimens from the Canary Islands and South Africa were compared against one another. The researchers concluded that the South African specimens represented a different taxon, and they suggested resurrecting Umbrina robinsoni as the name for this taxon as the form occurring off South Africa and in the western Indian Ocean.[5] In addition, there is some doubt about the occurrence of this species in tropical West African waters as specimens identified as this species are considered more likely to be Steindachner's drum Umbrina steindachneri.[6]
