Jan 1, 2025 · In this paper, we used otolith shape analysis, Linear Discriminant Analyses (LDA) to show that otolith shape can be used to distinguish between species and their putative hybrids, identified based on mitochondrial DNA and nuclear microsatellite data.

Argyrosomus japonicus, are commonly known as dusky kob or kabeljou in South Africa. They are found in the south-eastern seaboard of southern Africa where they occur from False Bay to southern Mozambique.

Swim bladder carrot-shaped with 28-38 arborescent appendages. Drumming muscles present in both sexes; urinary bladders large; sagitta typically Argyrosomus; pectoral fin axillary fold without scales; peritoneum unpigmented; anterior part of lateral line slightly curved. Occurs in estuaries, the surf zone and further offshore.

Namibian coast was determined using longitudinally sectioned otoliths. The special Von Bertalanffy growth model adequately described the growth of kob in both regions. Growth rate for kob in the south was validated using mark-recapture data, and similar growth rates were obtained using both methods. Growth of kob sampled

otoliths were collected and total fish length (nearest mm) and fish mass were recorded from male and female dusky kob caught by recreational and commercial linefishermen operating in estuaries, in the surf zone and nearshore (beyond the surf to 100 m deep) in KwaZulu/Natal, the South-Eastern Cape and the

Silver kob, Argyrosomus inodorus, is an important commercial and rec reational sciaenid fish (max. size 34 kg) that is known from northern Namibia on the west coast ofsouth ern Mrica to the Kei River on the east coast ofSouthMrica (Griffiths and Heemstra, 1995).

Western Indian Ocean: Mozambique to Port Elizabeth, South Africa; also from the west coast of Madagascar. Dorsal spines (total): 11; Dorsal soft rays (total): 26 - 28; Anal spines: 2; Anal soft rays: 6 - 7. Body silvery, fins orange-brown or yellowish (Ref. 4373). Found in coastal waters.

Apr 8, 2010 · The growth of silver kob Argyrosomus inodorus sampled from two regions (northern and southern) along the Namibian coast was determined using longitudinally sectioned otoliths. The special Von...

Apr 8, 2010 · The ages of dusky kob Argyrosomus japonicus, sampled from three regions along the South African eastern seaboard during 1991 and 1992, were determined from longitudinal sections of otoliths. The otoliths were selected from fish 35 – 1 750 mm total length.

The growth of silver kob Argyrosomus inodorus sampled from two regions (northern and southern) along the Namibian coast was determined using longitudinally sectioned otoliths. The special Von Bertalanffy growthmodel adequately described the growth of kob in both regions.
