    (2013) Van Zyl, Megan Elizabeth; Attwood, Colin; Kerwath, Sven
    Seabreams are an important family of fishes in the southern African recreational and commercial linefisheries. This family is known for its extreme longevity, slow growth and wide variety of reproductive styles. Red stumpnose are one of the most iconic species within this family, yet biological information is lacking on this species. Six hundred and seventy-eight specimens were collected from 1986 to 2012, ranging in size from 165 to 600 mm fork length. All specimens were dissected and morphological measurements taken. Gonads, stomachs and otoliths were removed from 237 individuals and presented. Otoliths were sectioned and independently aged by three readers, age agreement was reached on 183 fish.
