“…Studies on blood parameters in fish have been made on species of greatest commercial interest worldwide, such as rainbow trout (Oncorhynchus mykiss) (Clifton-Hadley et al 1987), turbot (Psetta maxima) (Burrows et al 2001), common carp (Cyprinus carpio) (Svetina et al 2002), Atlantic salmon (Salmo salar) (Sandnes et al 1988), and tuna (Thunnus maccoyii) (Rough et al 2005) among others. In the last decades, aquaculture in Latin America and the Caribbean showed the world 0 s highest average annual growth and studies on haematology of native species are increasing (Parma de Croux 1994;Tavares-Dias and Sandrim 1998;Tavares-Dias et al 1999Moraes et al 2002;Ranzani-Paiva et al 2003;Tavares-Dias and Mataqueiro 2004;Alesso et al 2005;Cazenave et al 2005;Ranzani-Paiva et al 2005;Oliveira-Ribeiro et al 2006). To date, there are few studies related to blood tissue in pejerrey.…”

Phylogenetic diversity in fish determines high interspecific variability in morphology as well as in physiological parameters. Moreover, several haematological variables and the organ composition of haemolymphopoietic sites may vary according to sex or season. The aim of this study was to establish the haematological parameters and the cellular composition of haemolymphopoietic organs in Odontesthes bonariensis, a commercially valuable fish species in Argentina, and also to determine gender or seasonal variations. Haematocrit exhibited the highest value in summer, while haemoglobin concentration was greater in summer and autumn. Erythrocyte count was higher in spring than autumn and winter, but did not differ with summer. The increase in these variables in seasons with higher water temperatures might be a compensatory mechanism to compensate the lower level of oxygen in the environment. Leucocyte formula and blast haemolymphopoietic cells in spleen and head kidney also showed annual variations since cells related to specific immune response, i.e., lymphocytes and thrombocytes, decrease in winter, whereas cells of the non-specific immune pathways, such as granulocyte, rise. The elevation of a particular type of circulating leucocyte was preceded by an increase in values of its precursor in blood in the previous season. Both, spleen and head kidney were active in haemolymphopoiesis, although with some differences in their activity during different seasons. Males showed higher values of circulating lymphoblasts and granulocytes than females, whereas females exhibited higher values of thrombocytes. This study corroborates the high interspecific variations in haematological parameters in fish that underlines the needing of basic studies in order to assess fish health status in new promising species for aquaculture.

ABSTRACT. Intensification of aquaculture production systems exposes fish to numerous stressors, which may negatively affect their health. This study determined the effects of increasing levels of dietary mannan oligosaccharides (ActiveMOS ® -Biorigin) on biochemical and hematological parameters of juvenile pacu, Piaractus mesopotamicus. Fish (44.04 ± 5.27 g) were randomly distributed into 24 tanks (500 L; 10 fishes per tank) and fed during 63 days with a commercial diet supplemented with 0.0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.5 and 2.0% MOS. Blood samples were collected at 42 and 63 trial. Red blood cell count (RBC) and total plasmatic protein were affected by dietary MOS levels (P < 0.05). Fish fed 1.0% dietary MOS presented higher neutrophils numbers when compared to fish fed control diet and fish fed 1.5% MOS for 42 days presented significant higher granulocytic cell numbers. During trial fish presented increased (P < 0.05) hematocrit, mean corpuscular volume, mean corpuscular hemoglobin and plasmatic glucose concentrations and decreased (P < 0.05) RBC, hemoglobin concentration, mean corpuscular hemoglobin concentration, white blood cell and differential leukocyte count. Dietary MOS levels did not present prebiotic effects for pacu and did not minimize stress effects on hematological and biochemical parameters for the species. Keywords: Piaractus mesopotamicus, mannan oligosaccharide, hematology, nutrition, prebiotic, fish. (Holmberg, 1887) alimentado con raciones suplidas con manan oligosacáridos (MOS) RESUMEN. La intensificación de los sistemas de producción acuícola expone a los peces a numerosos factores estresantes que pueden afectar negativamente su salud. Este estudio determinó el efecto de niveles crecientes de manan oligosacáridos (ActiveMOS ® -Biorigin) en la dieta respecto a parámetros bioquímicos y hematológicos de juveniles de pacu, Piaractus mesopotamicus. Los peces (44,04 ± 5,27 g) fueron distribuidos al azar en 24 tanques (500 L; 10 peces por tanque) y alimentados durante 63 días con una dieta comercial suplementada con 0,0; 0,2; 0,4; 0,6; 0,8; 1,0; 1,5 y 2,0% de MOS. Las muestras de sangre fueron colectadas los días 42 y 63 del experimento. El recuento de glóbulos rojo (RBC) y la concentración de proteínas plasmáticas totales fueron afectados por los niveles de MOS en la dieta (P < 0,05). Peces alimentados con dieta suplementada con 1,0% MOS presentaron mayor número de neutrófilos en comparación a peces alimentados con la dieta control y peces suplementados con 1,5% de MOS presentaron alto número de células granulocíticas (SGC) a los 42 días del experimento. Durante el ensayo, los valores de hematocrito, volumen corpuscular promedio y hemoglobina corpuscular media incrementaron (P < 0,05) y las concentraciones de glucosa plasmática, hemoglobina, concentración promedio de hemoglobina, glóbulos blancos, RBC y el recuento diferencial de los leucocitos disminuyeron (P < 0,05). Los niveles dietéticos de MOS no presentaron efectos prebióticos en pacus y no minimizaron los efectos del estrés sobre los pará...
