Resumo: The objective of this study was studied relative condition factor and hematological parameters of males and females of pacu Piaractus mesopotamicus were after the process of hormonal induction and spawning. Field research was carried out, with quantitative and qualitative measures in which thirty healthy fish were randomly collected, 14 females and 16 males. A blood collection was then carried out to analyze the following parameters: hematocrit, total plasma protein, number of erythrocytes, hemoglobin, hematimetric indices, mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCHC) concentration. Total and differential leukocyte and thrombocyte count and plasma glucose were also determined. The condition factor was similar for both sexes, with values close to 1. The total plasma protein and the number of circulating neutrophils were higher in females (P<0.05). The other parameters remained unchanged. These differences are an adaptation response to management. All values were close to those previously reported for pacu, P. mesopotamicus, under conditions of hygiene in the intensive farming system, indicating that the process of induction and spawning does not damage the well-being of the fish to the point of triggering changes in the factor of hematological condition and parameters.

Se realizó una investigación de campo, con medidas cuantitativas y cualitativas en las que se recolectaron al azar treinta peces sanos, 14 hembras y 16 machos. Luego se realizó una recolección de sangre para analizar los siguientes parámetros: hematocrito, proteína plasmática total, número de eritrocitos, hemoglobina, índices hematimétricos, volumen corpuscular medio (VCM) y concentración média de hemoglobina corpuscular (CHCM). También se determinaron el recuento total y diferencial de leucocitos y trombocitos y glucosa en plasma. El factor de condición fue similar para ambos sexos, con valores cercanos a 1. La proteína plasmática total y el número de neutrófilos circulantes fueron más altos en las hembras (P<0.05). Los otros parámetros permanecieron sin cambios. Estas diferencias son una respuesta de adaptación a la manejo. Todos los valores fueron cercanos a los reportados previamente para pacu, P. mesopotamicus, bajo condiciones de higiene en el sistema de cultivo intensivo, lo que indica que el proceso de inducción y desove no causa daño al bienestar de los peces hasta el punto de desencadenar cambios en el factor de condición hematológica y parámetros.Objetivou-se avaliar o fator relativo de condição relativo e os parâmetros hematológicos de machos e fêmeas de pacu Piaractus mesopotamicus após o processo de indução hormonal e desova. Foi realizada pesquisa de campo, com medidas quantitativas e qualitativas em que foram avaliados 30 peixes saudáveis, coletados aleatoriamente, sendo 14 fêmeas e 16 machos. Procedeu-se então uma coleta de sangue para análise dos seguintes parâmetros: hematócrito, proteína plasmática total, número de eritrócitos, hemoglobina, índices hematimétricos, volume corpuscular médio (VCM) e concentração de hemoglobina corpuscular média (CHCM). Contagem total e diferencial de leucócitos e trombócitos e a glicose plasmática também foram determinadas. O fator de condição foi semelhante para ambos os sexos, com valores próximos a 1. A proteína plasmática total e o número de neutrófilos circulantes foram maiores nas fêmeas (P<0,05). Os demais parâmetros permaneceram inalterados. Essas diferenças constituem uma resposta de adaptação ao manejo. Todos os valores foram próximos aos relatados anteriormente para o pacu, P. mesopotamicus, em condições de higidez no sistema de cultivo intensivo, indicando que processo de indução e desova não causa prejuízos ao bem-estar dos peixes a ponto de desencadear alterações no fator de condição e parâmetros hematológicos.Research, Society and Development2020-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/333810.33448/rsd-v9i5.3338Research, Society and Development; Vol. 9 No. 5; e181953338Research, Society and Development; Vol. 9 Núm. 5; e181953338Research, Society and Development; v. 9 n. 5; e1819533382525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/3338/4716Copyright (c) 2020 Arlene Sobrinho Ventura, Sheila Nogueira de Oliveira, Joaquim Azambuja Duarte Junior, Tuany Trindade Silva, Andrea Maria de Araújo Gabrielinfo:eu-repo/semantics/openAccessVentura, Arlene SobrinhoOliveira, Sheila Nogueira deDuarte Junior, Joaquim AzambujaSilva, Tuanny TrindadeGabriel, Andrea Maria de Araújo2020-08-20T18:06:36Zoai:ojs.pkp.sfu.ca:article/3338Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:34.187393Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
