Hidrográfica do Tocantins abrange os estados de Goiás, Tocantins, Pará,
Maranhão, Mato Grosso e o Distrito Federal. Grande parte situa-se na região
Centro-Oeste, desde as nascentes dos rios Araguaia e Tocantins até a sua
confluência, e daí, para jusante, adentra na Região Norte pelo Estado do Pará,
nas proximidades do município de Bom Jesus do Tocantins e São João do Araguaia,
próximo do famoso Bico do Papagaio, até a sua foz no rio Pará. Seus principais
tributários são, Araguaia e Itacaiúnas, também considerados grandes pólos da
pesca esportiva e comercial.



A
construção da barragem da UHE de Tucuruí entre o médio e baixo Tocantins
provocou uma grande mudança na vida aquática desse imenso pesqueiro. Provavelmente,
a mais profunda modificação ambiental já vista nos rios da Amazônia. Quem ficou
a montante, perdeu espécie que faziam migrações rio acima como, dourada e
filhote, porém, foram contemplados pela abundância de espécies como, Curimatá,
Mapará, Jaraqui, Caranha e Tucunaré, que se reproduziram e&nbsp; espalharam-se pelo imenso lago formado pela
barragem, uma área de 3.000 km² (ELETRONORTE). Responsável pela formação do
maior lago artificial do País. Tornando os municípios de Tucuruí, Breu Branco,
Jacundá, Itupiranga e Marabá como a mais nova área de pesca da Amazônia sejam
de caráter comercial como esportiva. Enquanto que os municípios à jusante como,
Baião, Mocajuba, Cametá, Limoeiro do Ajuru e Abaetetuba, deixaram de ter em
suas redes e anzóis os peixes&nbsp; que
desciam no verão, depois das longas migrações para procriação e engorda no
início do inverno amazônico.





Cerca
de 70% da produção de pescado, do trecho entre a barragem e o município de
Marabá, no estado do Pará é destinado ao mercado maranhense.




A
pesca que acontece no baixo Araguaia, na divisa entre o Pará e o Estado do
Tocantins, é semelhante em quase todos os aspectos do baixo e médio rio Tocantins: espécies,
embarcações, apetrechos e modo de comercialização. Também tem potencialidade
para a pesca esportiva, já sendo realizados vários torneios de pesca nos
municípios que margeiam esse rio, tanto no Estado do Pará e como no Tocantins.





As
principais espécies comerciais de região são: Acará, Acari, Branquinha,
Caranha, Curimatá, Jaraqui, Mapará, Cachorra, Jaú, Pacu, Pirarara, Pescada Branca,
Surubim, Tambaqui, Tucunaré.
