Resumo: | The objective of this study was to evaluate the effect of different prey concentrations (50; 100; 150 and 200 artemia nauplii post-larvae-1 day-1) and salinized water (0; 1 and 2 g L-1) on larviculture of Pyrrhulina brevis, an Amazonian ornamental fish. The experiment was carried out in a completely randomized design, in a 4x3 factorial design, with three replicates. A total of 360 post-larvae were randomly distributed in 36 aquariums (1L), to 10 post-larvae L-1. At the end of the experimental period (15 days) the post-larvae were measured, weighed and counted. No interaction was identified between the prey concentrations and salinized water for all evaluated parameters. The best growth results, both for length and weight, were observed in the post-larvae that received 150 and 200 artemia nauplii post-larvae-1 day-1, while the lower survival rate was observed in post-larvae fed 50 and 100 artemia nauplii post-larvae-1 day-1. The final length and length gain were higher when the post-larvae were reared in salinized water at 1 and 2 g L-1, while the final weight, weight gain and specific growth rate were higher in post-larvae submitted to 1 g L-1 of salinized water. The uniformity of the batch for weight and length of the fish showed no significant difference, independent of the prey concentrations and salinized water used. Thus, the supply of 150 artemia nauplii post-larvae-1 day-1 in salinized water at 1 g L-1 is recommended during the first fed of Pyrrhulina brevis. |

El experimento se realizó en un diseño completamente al azar, en un esquema factorial 4x3, con tres repeticiones. Un total de 360 post-larvas se distribuyeron al azar en 36 acuarios (1L), a 10 post-larvas L-1. Al final del período experimental (15 días), se midieron, pesaron y contaron las post-larvas. No se identificó interacción entre las concentraciones de presas y el agua salina para todos los parámetros evaluados. Los mejores resultados de crecimiento, tanto en longitud como en peso, se observaron en las post-larvas que recibieron 150 y 200 nauplios de artemia post-larva-1 día-1, mientras que la tasa de supervivencia más baja se observó en las post-larvas alimentadas con 50 y 100 nauplios de artemia post-larva-1 día-1. La longitud final y la ganancia de longitud fueron mayores cuando las post-larvas se criaron en agua salina a 1 y 2 g L-1, mientras que el peso final, la ganancia de peso y la tasa de crecimiento específico fueron mayores en la post-larvas sometidas a 1 g L-1 de agua salina. La uniformidad del lote para el peso y la longitud de los peces no mostró diferencias significativas, independiente de las concentraciones de presas y agua salina utilizadas. Por lo tanto, se recomienda suministrar 150 nauplios de artemia post-larva-1 día-1 en agua salina a 1 g L-1 durante la primera alimentación de Pyrrhulina brevis.Objetivou-se com este estudo avaliar o efeito de diferentes concentrações de presas (50; 100; 150 e 200 náuplios de artêmia pós-larva-1 dia-1) e água salinizada (0; 1 e 2 g L-1) na larvicultura de Pyrrhulina brevis, um peixe ornamental da Amazônia. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema fatorial 4x3, com três repetições. Um total de 360 pós-larvas, foram distribuídas aleatoriamente em 36 aquários (1L), a 10 pós-larvas L-1. Ao final do período experimental (15 dias), as pós-larvas foram medidas, pesadas e contabilizadas. Não foi identificada interação entre as concentrações de presas e a água salinizada para todos os parâmetros avaliados. Os melhores resultados de crescimento, tanto em comprimento quanto em peso, foram observados nas pós-larvas que receberam 150 e 200 náuplios de artêmia pós-larva-1 dia-1, enquanto que a menor taxa de sobrevivência foi observada nas pós-larvas alimentadas com 50 e 100 náuplios de artêmia pós-larva-1 dia-1. O comprimento final e o ganho de comprimento foram maiores quando as pós-larvas foram criadas em água salinizada a 1 e 2 g L-1, enquanto que o peso final, o ganho de peso e a taxa de crescimento específico foram maiores nas pós-larvas submetidas a 1 g L-1 de água salinizada. A uniformidade do lote para peso e comprimento dos peixes não mostrou diferença significativa, independente das concentrações de presas e água salinizada utilizada. Dessa forma, recomenda-se o fornecimento de 150 náuplios de artêmia pós-larva-1 dia-1 em água salinizada a 1 g L-1 durante a primeira alimentação de Pyrrhulina brevis.Research, Society and Development2020-07-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/558210.33448/rsd-v9i8.5582Research, Society and Development; Vol. 9 No. 8; e381985582Research, Society and Development; Vol. 9 Núm. 8; e381985582Research, Society and Development; v. 9 n. 8; e3819855822525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/5582/4924Copyright (c) 2020 Leonnan Carlos Carvalho Oliveira, Elviro dos Anjos Silva Neto, Arlindo dos Santos Pinheiro Junior, Bruno José Corecha Fernandes Eiras, Galileu Crovatto Veras, Lorena Batista de Moura, Daniel Abreu Vasconcelos Campeloinfo:eu-repo/semantics/openAccessOliveira, Leonnan Carlos Carvalho deSilva Neto, Elviro dos AnjosPinheiro Junuior, Arlindo dos SantosEiras, Bruno José Corecha FernandesVeras, Galileu CrovattoMoura, Lorena Batista deCampelo, Daniel Abreu Vasconcelos2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5582Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:03.504711Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
