Morphological description

Head and body are reddish orange dorsally and silvery white below with irregular black spots scattered over the body. Some individuals have 5 -7 red bars on the body. The soft dorsal and anal membranes are often blackish. Large adult makes often develop a bulbous forehead. Body depth is greater than the head and is 2 – 2.4 times the SL. The dorsal fin has 11-12 spines and 10-11 rays. The anal fin has 7-9 rays. The pectoral fins are longer than the head and have 17 rays. Jaws have 4-6 slender canines and 3 or more series of small molars behind. There are 52-55 lateral line scales. Interorbital area, pre-opercule margin and base of soft dorsal and anal fins are scaly (Heemstra and Heemstra 2004).

Global distribution

Endemic to South Africa and only found from Cape Point to East London (Fischer and Bianchi 1984, Smith and Heemstra 1986). Red stumpnose have been recorded as far north as Margate on the KZN south coast (Heemstra and Heemstra 2004). It must be noted that this could be due to confusion with a similar species C. anglicus which is also sometimes referred to using the common name "red stumpnose" (B. Mann, ORI, pers. comm.).

SA distribution

As above, Red stumpnose are most abundant in the South West Cape from Cape Point to Arniston, in the South East Cape from Jefferys Bay to East London and in the southern Transkei (NMLS, unpubl. data).

Movement

Red stumpnose are extremely resident (Wilke and Griffiths 1999) and may form seasonal aggregations (NMLS, unpubl. data).

Trophic strategy

Adult red stumpnose usually feed on a variety of reef invertebrates such as ophiuroids, gastropods and polychaete worms (van Zyl 2013), but also take sea urchins, octopus and crabs (Heemstra and Heemstra 2004).Juveniles prefer softer prey such as malacostraca. As they grow their diet shifts to contain more hard prey gastropods (van Zyl 2013).

Reproduction

Red stumpnose are late gonochorists (sensu rudimentary hermaphrodite) that produce small pelagic eggs (Buxton 1985, van Zyl 2013). They spawn from October to January both in the South Eastern Cape (CD Buxton, DIFS, unpubl. data) and on the central Agulhas Bank, with the peak season in December (van Zyl 2013). Males reach sexual maturity at an average age of 2.2 years when they are 212 mm FL and females at 3.9 years when they reach a length of 249mm FL (M. van Zyl, UCT, unpubl. data).

Uses

Seasonal component of the commercial linefishery, especially on the Agulhas Banks (Crawford and Crous 1982, van der Elst 1993). Also taken by the recreational skiboat fishery and spearfishery (Smale and Buxton 1985, Brouwer 1997, Mann et al. 1997b). Incidental catches taken by inshore trawlers operating in the Mossel Bay to Cape Infanta area (van der Elst 1993, Attwood et al. 2011).
