The Kob is probably one of the most targeted edible saltwater fish off South Africa’s coastline and is known by many names in Southern Africa: Kob, Daga, Drum, Daga Salmon and Kabeljou. The Kob grow to big sizes and put heavy tackle to the test. They are also a great species to target on boats in estuaries with lures. Kob are aggressive fish and mainly move around in shoals where they feed on smaller fish and crustaceans.
Most adults migrate from the Cape to KwaZulu-Natal to spawn between August and November. Juveniles enter the upper reaches of estuaries where they remain until they about 15cm. The juveniles prefer the sandy or muddy substrates in shallow embayments.
Most kob species are voracious, shoaling predators and some species have become highly specialised for feeding in their muddy, murky environment. Their lateral line system (a sensory system found in all fish that enables them to detect vibrations and pressure changes in the water) is very well developed and this, in conjunction with the sensory barbles which some have on their snouts, makes the kob less reliant on sight when feeding. Small fish, crustaceans such as prawns and crabs, and molluscs such as squid and cuttlefish are all eaten by the various kob species.
