Catch it
Step by step, from first cast to landing.
Step-by-step: how to catch it
- Go where it lives: Estuaries, lagoons and sandy coasts from the Western Cape of South Africa up East Africa to the Arabian Gulf, Socotra, the Seychelles, Madagascar and the northwest coast of India; tolerates near-fresh water.
- Rig up: Light 7–9 ft spinning rod or a 6–8 weight fly rod. 12–20 lb fluorocarbon.
- Pick your bait: Live mud prawn or sand prawn (pumped from the banks), worms and small crabs. Lures: Small crab and shrimp flies, small soft plastics.
- Fish it: Cast a live prawn on light weight onto the banks with the rising tide; on fly, cast a small crab pattern ahead of tailing fish and let it sink.
- Time it: Day on the flats; dusk and night in channels. Rising tide onto the banks, especially spring tides.
- Fishing techniques
Cast a live prawn on light weight onto the banks with the rising tide; on fly, cast a small crab pattern ahead of tailing fish and let it sink.
- BigJoe's tip
Look for little puffs of mud and tails breaking the surface on the banks — those are grunter digging for prawns.
- Catch and release
Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.
Clean & cook
Is it good to eat, and how to prepare it.
- Edibility
Excellent eating — one of the best-tasting fish in its range.
- Cleaning
Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.
- Cooking suggestions
Excellent, firm white meat — fried, grilled or baked whole.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Sharp dorsal spines; estuaries in KwaZulu-Natal and Mozambique can have crocodiles and Zambezi (bull) sharks.
- Regulations
South Africa: 5 per person per day with a 40 cm (16 in) minimum; pumping prawns needs a permit and has daily limits. Some estuaries have no-take zones. South Africa requires a recreational fishing permit (sold at post offices and online), with daily bag limits, minimum sizes and closed seasons for many species; Namibia and Mozambique sell their own licenses. Recreational catches may not be sold, and marine protected areas have their own rules.
- Conservation
Release fish under the size limit carefully; estuaries are their nursery.
