Spotted Grunter
Pomadasys commersonnii
Also known as: Spotted grunter, tiger, knorhaan
Illustration: gardenroutefishing.co.za
The estuary favourite from Stilbaai to Swartkops. Grunter feed head-down on prawn banks, their tails waving above the surface — 'tailing' fish offer some of SA's most exciting sight-fishing.
Where & how: every major estuary on this coast. Pump mud or sand prawn at low tide (permit and limits apply), then fish it on light traces across the banks on the pushing tide. Fly anglers throw prawn imitations at tailing fish. Patience is everything — grunter mouth a bait endlessly before committing.
Tackle: light 7-9 ft spinning rods, 4-8 kg line, small hooks, minimal weight.
Table: good eating, though many specialists release their fish. 40 cm minimum, 5 per day.

When to catch Spotted Grunter
Pushing tide over prawn banks; summer
Best on the pushing tide over the prawn banks and the first of the ebb in the channels.
Pushing tide on spring tides; moon less critical
Feed keenly in warm estuary water, roughly 18–24 °C in summer.
🥅 Landing
Use a knotless landing net; support the fish and keep it wet.
♻️ Release
Barbless or de-barbed hooks help; wet hands, quick photo, and slide it back gently.
