  • Hematological parameters of Brycon amazonicus (Bryconidae) broodstock in captivity [Parámetros hematológicos de reproductores de Brycon amazonicus (Bryconidae) en cultivo]
    'Universidad Nacional Mayor de San Marcos Vicerectorado de Investigacion', 2019
    Co-Authors: Gonzales Anaí, Curto Giana, Fernández-mendez Christian
    Abstract:

    The objective of this study was to determine the hematological values of Brycon amazonicus broodstock under culture in Iquitos, Peru. Blood samples were taken from 12 specimens (1.62 ± 0.45 kg and 51.38 ± 2.93 cm) maintained in earthen ponds and fed twice a day with a commercial diet with 22% crude protein. The fish were collected with a net and anesthetized with eugenol. Blood extraction was performed with disposable syringes containing EDTA (10%). The values obtained from the erythrocytic series were: hematocrit 53.3 ± 4.8%; hemoglobin 20.1 ± 3.2 g/dl; erythrocytes 2.8 ± 0.5 x106/µl; VCM 194.4 ± 54.4 fl; CHCM 37.7 ± 4.8 g/dl; HCM 72.6 ± 17.7 pg. The number of leukocytes was 8.1 ± 6.0 x103/µl. In the differential count of leukocytes, the lymphocytes and monocytes had greater proportion in comparison with neutrophils, eosinophils and basophils. The total serum protein was 3.7 ± 0.4 g/dl and the glucose was 60.2 ± 39.1 mg/dl. The values found for B. amazonicus were compared with other species of the genus Brycon showing some variations, but within the range reported for teleost fishes.Revisión por pares

Se tomaron muestras de sangre de 12 ejemplares (1.62 ± 0.45 kg y 51.38 ± 2.93 cm) mantenidos en estanques de tierra y alimentados dos veces al día con una dieta comercial extruida al 22% de proteína bruta. Los peces fueron colectados con una red y anestesiados con eugenol. La extracción de sangre se realizó con jeringas descartables conteniendo EDTA (10%). Los valores obtenidos de la serie eritrocítica fueron: hematocrito 53.3 ± 4.8%; hemoglobina 20.1 ± 3.2 g/dl; eritrocitos 2.8 ± 0.5 x106/μl; VCM 194.4 ± 54.4 fl; CHCM 37.7 ± 4.8 g/dl; HCM 72.6 ± 17.7 pg. El número de leucocitos fue de 8.1 ± 6.0 x103/μl. En el recuento diferencial de leucocitos, los linfocitos y monocitos fueron las células de mayor proporción en comparación con los neutrófilos, eosinófilos y basófilos. La proteína total sérica fue de 3.7 ± 0.4 g/dl y la glucosa de 60.2 ± 39.1 mg/dl. Los valores encontrados para B. amazonicus fueron comparados con otras especies del género Bryconmostrando algunas variaciones, pero dentro del rango reportado para peces teleósteos
