Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Arapaima
Max. size:	450 cm TL (male/unsexed; Ref. 6398); max. published weight: 200.0 kg (Ref. 557)
Environment:	demersal; pH range: 6 - 6.5; dH range: 10
Climate:	tropical; 25 - 29°C; 5°N - 11°S
Global Importance:	fisheries: commercial; aquaculture: commercial; aquarium: public aquariums
Resilience:	Low, minimum population doubling time 4.5 - 14 years (tm=4-6; Fec=47,000)
Distribution:	South America: Amazon River basin. International trade restricted (CITES II, since 1.7.75). The active fishing of this fish has reduced both the population size, and occurrence of large individuals, especially around the populated regions of the Amazon (Ref. 50891).
Biology:	Often referred to as the largest freshwater fish. Builds a nest of about 15 cm depth and 50 cm width in sandy bottoms. Spawns in April and May and guards the eggs and the young. Obligate air breather. The fish rises to the surface of the water and inspires air in a noisy, distinctive gulp, which is reported to carry for long distances (Ref. 50891). Threatened due to over harvesting (Ref. 58490)
Threatened:	Data deficient, see IUCN Red List  , (Ref. 36508)
