Stromateoidei in the Southern part of Africa and adjacent areas (distribution, biology, fisheries).
A total of 24 species of stromateiod fishes (Stromateoidei) from 5 families (except Amarsipidae) were registered on the shelf of the southern part of Africa (off Angola, Namibia, South Africa and Mozambique) and in the adjacent areas of the Atlantic and Indian oceans from YugNIRO data collected in research cruises from 1972 to 1990. Some species are forming dense concentrations at the banks, mountains and elevations in the systems of Whale, Mozambique, Madagascar and Western Indian ridges and vulnerable for fishing gears. Twelve species: Hyperoglyphe antarctica, Schedophilus huttoni, S. maculatus, S. ovalis, Centrolophus niger (Centrolophidae), Cubiceps caeruleus, C. pauciradiatus, C. capensis, Psenes pellucidus, Parapsenes rotundas (Nomeidae), Tetragonurus cuvieri, T. atlanticus (Tetragonuridae), are common for the western and eastern coasts of Africa. Nine species are found only eastwards to Africa, they are as follows: Tubbia tasmanica, Psenopsis obscura (Centrolophidae), Cubiceps squamiceps, Nomeus gronovii, Psenes maculatus, P. arafurensis, P. cyanophris, P. whiteleggii (Nomeidae), Ariomma indica (Ariommidae). Three species dwell only near the western coast: H. moselii, S. pemarco (Centrolophidae), Stromateus fiatela (Stromateidae). On the shelf of the southern part of Africa nomeids Cubiceps squamiceps and butterfishes Ariomma indica as well as Centrolophidae in the Namibia area may have the commercial interest. The densest concentrations of nomeids were found in the area of Bazaruto Island (Mozambique). Butterfish is one of the most abundant fishes on the Mozambique shelf in 30-200 m depths caught with bottom trawl. The best catches, up to 900 kg per trawling hour were reached in the area Boa Paz (southern Mozambique); they reached 700 kg on the Sofala Shallow (central coast of Mozambique).
