Arapaima gigas
One of the world's largest freshwater fish, an air-breathing Amazonian giant clad in huge red-edged scales. It surfaces to gulp air in oxygen-poor floodplain lakes, hunting fish and invertebrates. Large flies and lures near the surface, on very heavy tackle, are used where legal.
0 – 10 m
Large topwater lures or heavy fly lines worked near the surface in oxbow lakes and floodplain lagoons on very heavy tackle, where legally permitted.
Excellent white flesh, a vital protein source for Amazonian communities; now farmed and sustainable aquaculture fish is recommended over wild-caught specimens.
No close look-alikes in its range; the enormous red-edged scales, distinctly elongated body, and air-gulping behavior at the surface are unmistakable.
