The Kob is a migratory fish found along the⁣ coasts of Southern⁤ Africa, from Angola to Mozambique. Their migration patterns are influenced by availability of food and breeding sites.


Kob​ primarily inhabit the nearshore environments, but ⁣can venture into depths up to⁢ 100 metres. They are also known to enter estuaries and can​ tolerate a wide range of ⁢temperatures.

When ​and Where‌ to See

While Kob can‍ be spotted throughout the year, their presence is more notable from late spring to early winter. They are more⁣ likely to be ​spotted ⁣during late afternoon or early morning hours.

Best Fishing Locations

Some ‍of the best fishing locations for Kob include the Orange River ⁤Mouth, Breede River, Sodwana Bay, and⁢ Nahoon. When ​specific locations are‌ not that important, look for areas with deep channels, rocky reefs or drop-offs where ⁤kob like to hunt.

How to‌ Catch

Kob are known to fall for⁤ a variety‌ of baits. ⁢Popular‍ choices include squids, sardines, and mackerels. Beach and estuary⁣ fishing are common techniques, although some fishers also prefer trawling or ‍fly fishing. The best times for catching Kob are usually ⁤around dawn ⁣and dusk.

Identification Guide

The Kob is silver-green to bronzy, with a slightly darker‌ dorsal area. ⁤The body shape is elongated, with ‍a broad rounded head. It is sometimes‍ confused with ⁢other members of the Sciaenidae family, but can be identified by its unique mouth shape and scale pattern.
