Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. 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.
  2. Rig up: Light 7–9 ft spinning rod or a 6–8 weight fly rod. 12–20 lb fluorocarbon.
  3. 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.
  4. 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.
  5. 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.

6

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.
