Resumo: Arapaima gigas (pirarucu) is a large fish greatly appreciated in Amazon region. The present work determined the weight-length relationship and the relative condition factor (Kn) of eviscerated pirarucu specimens from the extractive reserve (RESEX) of Juruá river, Amazonas, Brazil. The relative frequency distributions by weight class indicated amplitude between 20,000 and 115,000g and the classes of greatest frequency were between 30,000 and 80,000g. The equation that describes this relationship is W = 0.0092L3.0157, showing an isometric growth. Kn presented values of 0.98 ± 0.01, ranging between 0.94-1.01. The results indicate that fish stock of A. gigas in the RESEX of Juruá river presents good management conditions since most of the fish caught presented commercial weight and high utilization of meat, and also the equations of weight-length relationship and Kn values can be considered as reference for A. gigas eviscerated of the studied region.Keywords: pirarucu; biometric; homeostasis; management.

Neste trabalho foram determinados a relação peso-comprimento e o fator de condição relativo (Kn) de espécimes de pirarucu eviscerados, da Reserva Extrativista do Rio Juruá, Amazonas. As distribuições de frequências relativas por classe de peso indicaram uma amplitude entre 20.000 e 115.000 g, onde as classes de maior frequência foram as compreendidas entre 30.000 e 80.000 g. A equação que descreve a relação é W = 0.0092L3,0157,demonstrando um crescimento do tipo isométrico. O Kn apresentou valor médio de 0,98 ± 0,01, com variação entre 0,94-1,01. Os resultados do presente estudo nos permitem concluir que o estoque pesqueiro de A. gigas da RESEX do baixo rio Juruá encontra-se em boas condições de manejo, visto que a maior proporção dos peixes pescados esteve dentro da faixa de peso comercial e com maior aproveitamento de carne, alem do mais as equações da relação peso-comprimento e os valores do Kn podem ser utilizadas como parâmetros de referencias para o A. gigas evisceradoda região estudada.Palavras-chave: pirarucu, biometria, bem estar, manejo.Universidade Federal do AmapáCAPESda Cunha, Gilson SilvaLemos, Jefferson Raphael GonzagaPantoja-Lima, JacksonAride, Paulo Henrique Rochados Santos, Suelen MirandaAraújo, Rayza LimaOliveira, Adriano Teixeira de2014-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/115310.18561/2179-5746/biotaamazonia.v4n4p124-126Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 4, n. 4 (2014); 124-1262179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPenghttps://periodicos.unifap.br/index.php/biota/article/view/1153/v4n4p124-126.pdfAmazônia; Amazonas; JuruáAtualColeta de biometriaDireitos autorais 2014 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-03-29T17:56:09Zoai:ojs.pkp.sfu.ca:article/1153Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-03-29T17:56:09Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
