Pirarucu Arapaima gigas
(Osteoglossomorpha: Osteoglossidae) is a large carnivorous fish species of high commercial value and great aquaculture potential in the Amazon region.
Schinz, 1822, commonly known as pirarucu or arapaima, is considered one of the biggest freshwater fish reaching approximately 200 Kg and 2.5 m long (Ono, Roubach, & Pereira-Filho, 2003; Saint-Paul, 1986).
Among the species most exploited and consumed by the regional population, the pirarucu Arapaima gigas
(Schinz 1822), known as Amazon cod, is highly valued in the market, especially when its meat is marketed dried and preserved with salt.
The absence of mortality during transportation found in this study was also recorded for pirarucu (Arapaima gigas
), but with a shorter transportation time of 3 hours (Brandao, Gomes, Crescencio, & Carvalho, 2008).
(Schinz, 1822) (Osteichthyes: Arapaimidae) is the world's largest scale fish, may reach 3 m length, presents wide geographical distribution in the Amazonian region and occurs in the floodplain of the rivers Araguaia-Tocantins, Solimoes-Amazonas and their effluents, Amazonas river in the Peruvian Andes, tributaries of the river systems Essequibo and Rupununi the Guiana (Imbiriba, 2001).
Measurements of net ion fluxes provide a good correlation with stress of transport in Arapaima gigas
(pirarucu) (GOMES et al., 2006), Carnegiella strigata (marbled hatchetfish), Paracheirodon axelrodi (cardinal tetra) (GOMES et al., 2008; 2009) and silver catfish (PARODI et al., 2014).
This time I fly fished the Rewa River, famed for the arapaima (arapaima gigas
), out of a fly fishing-only lodge set up by the Costa del Mar sunglasses company (https:// www.costadelmar.com/insidecosta/protect-guyana) and other parties.
Pirarucu, Arapaima gigas
(Shinz 1822), is the largest Amazonian and freshwater fish with scales in the world.
Noteworthy Catches--This arapaima (Arapaima gigas
), also called pirarucu, was caught by Alan Atkins, well known carp angler, while fishing at Gillhams Fishing Resort in Krabi, Thailand.
