1

Know it

Spot it, size it up and learn its habits.

Identification

Long, thick gray to brown body covered in big heavy scales, a small mouth, a short pointed head, and long dorsal and anal fins set far back near the rounded tail. Related to the South American arapaima and arowanas.

Typical size

3–10 lb.

Maximum size

About 3 ft and about 22 lb (10 kg).

Diet

Mud and the small things in it: plankton, plant debris, insect larvae, snails and tiny crustaceans — it filters food with special gill rakers.

Behavior

An air-breather that can live in swampy, low-oxygen water. Parents build a round nest in flooded vegetation and guard the young.

Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Native to the Sahel rivers and lakes — the Senegal, Gambia, Volta, Niger, Bénoué, Lake Chad, the Nile and Lake Turkana; introduced into reservoirs in Central Africa, the Congo basin and Madagascar.
  2. Rig up: Light to medium spinning or float rod. Not needed.
  3. Pick your bait: Small worms, bread or dough on tiny hooks; it is mostly caught in nets and traps, rarely on a hook. Lures: Hardly ever takes lures.
  4. Fish it: Float-fish small baits in slow, weedy water where fish are seen rolling. Be ready for a strong, heavy fish on light gear.
  5. Time it: Day; watch for fish rolling at the surface to gulp air. No tide — rising floodwater is the key.
Fishing techniques

Float-fish small baits in slow, weedy water where fish are seen rolling. Be ready for a strong, heavy fish on light gear.

BigJoe's tip

This is more a curiosity than a sport fish — if you see one rolling, try a tiny bait right where it came up.

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

Good eating when fresh.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Good eating and farmed in West Africa — smoked, grilled or in stews.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Hippos and crocodiles live in the same floodplains and swamps.

Regulations

Mostly a food fish for local fishers; where it's been introduced outside its native range, don't move live fish to new waters. Each African country sells its own fishing license, and national parks, game reserves and many lodges charge separate rod or park fees; some lakes and rivers have closed seasons or catch-and-release rules — check before you go.

Conservation

Introduced populations have hurt native fish in some countries; never move it.
