Summary: | Due to the importance of ornamental fishing of silver arowana, as well as, Lago Grande lake as one of the main areas for capturing baby arowanas in Peru, the present study aimed to evaluate the productivity and the biological-reproductive characteristics of the species in the lake, which is located in the lower basin of the Putumayo River and represents an area preferred by fishermen because the important populations of silver arowana inhabiting it. Analysis of population density, biometrics, sexual maturity, spawning, fecundity, sex ratio, water level of the lake and production of baby arowana were made. The study was developed between March and July of 2012 and to implement the activities of the study was important the participation of the Association of Fishermen “Fronteras Vivas”. In general, the population density extrapolated to the lake area was 1.29 fish/ha. Of these, the density of progenitors in the lake was 1.19 fish/ha. Also, male animals had total length, standard length and total weight higher than females and it was observed that the spawning period occurred in synchronization with the start of the growing of the hydrological regime. The average number of oocytes produced by females of silver arowana in the study area was 201 and the sex ratio was equilibrated. Furthermore, the study shows the capacity of production of the lake. In order to this the water lever influenced in the production of baby arowanas. It is important to continue studying the species for regulate the fishing and recover populations.Keywords: baby arowana; production; ornamental trade; length of first sexual maturity; fishing. |

Devido à importância da pesca ornamental de aruanã, e da lagoa Lago Grande como uma das principais áreas para a captura de alevinos de aruanã no Peru, o presente estudo tive como objetivo avaliar a produtividade e as características reprodutivas na espécie na lagoa, a mesma que está localizada na bacia baixa do Rio Putumayo e representa uma das áreas de pesca preferidas pela importante população de aruanã que a habitam. Foram feitas análises de densidade populacional, biometria, maturidade sexual, desova, fecundidade, proporção sexual, níveis da água na lagoa e sobre a produção de alevinos de aruanã. O estudo foi desenvolvido entre março a julho de 2012 e as atividades foram realizadas em parceria com a Agrupação de Pescadores “Fronteras Vivas”. De modo geral, a densidade populacional extrapolada à área da lagoa foi de 1.29 peixes∕ha. Daqueles, a densidade de progenitores na lagoa foi de 1.19 peixes∕ha. Além disso, os machos tiveram comprimento total e padrão e peso total maior do que as fêmeas, e foi observado que o período de desova ocorreu em sincronia com o início da crescente no nível das águas. A média de oocitos produzidos por fêmeas de aruanã foi de 201 e a proporção sexual foi equilibrada. Assim mesmo, o estudo mostra a capacidade de produção da lago. Nesse sentido, o nível da água influenciou na produção de alevinos de aruanã. É importante continuar os estudos da espécie para regulamentar a pesca e recuperar populações.Palavras-chave: alevinos de aruanã, produção, comércio ornamental, comprimento de primeira maturidade sexual, pesca.Universidade Federal do AmapáPEDICP-Ministerio de Agricultura y RiegoCortegano, Carlos Andre AmaringoPinedo, Luis Alfredo MoriIbanez, Luis Alberto MoyaRamÃrez, Mauro VásquezRuiz, Pablo Soria2014-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/106410.18561/2179-5746/biotaamazonia.v4n4p21-26Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 4, n. 4 (2014); 21-262179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPenghttps://periodicos.unifap.br/index.php/biota/article/view/1064/v4n4p21-26.pdfAmazônia; Putumayo; Loreto; Peru; AméricaAmazônia; Putumayo; Loreto; Peru; AméricaDireitos 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/1064Revistahttp://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 |
