“…Observou-se que houve predominância de linfócitos seguidos de neutrófilos e monócitos na contagem diferencial de leucócitos, semelhante ao observado por Ezzat et al (1974), Lea Master et al (1990), Tavares-Dias & Faustino (1998) A predominância de linfócitos no sangue de peixes não está bem esclarecida. Nos tecidos, as células mononucleares (linfócitos e macrófagos) prevalecem na reação de defesa do organismo, porém, em situações de estresse, o número de linfócitos circulantes diminui.…”

Pesq. Vet. Bras. 32(Supl. The present study evaluated the hematological and biochemical parameters of adult tilapia (Oreochromis niloticus) under the influence of the physiological stress factor in animals submitted to air exposure during fattening in raceway system. Blood cell count, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), leukogram, differencial leukocyte count, platelet, glucose, total protein, cholesterol, triglycerides and electrolytes (calcium, chloride, sodium and potassium) were analyzed. The results showed a uniform distribution for red blood cells, hematocrit, hemoglobin, secondary Wintrobe indices, total protein, glucose, cholesterol, and serum ions, indicated by a relatively low variation coefficient. There was positive correlation only for total white blood cells, organic defense cells (neutrophils and lymphocytes), glucose, cholesterol, sodium and calcium. As for the leukocytes (WBC), as the animals were exposed to aeration, the number of leukocytes gradually decreased (leukopenia), simultaneously occurring neutrophilia and lymphopenia. The glycemic index was a good indicator of physiological stress due to hyperglycemia (82.0+20.88mg/dL) demonstrated in the treatments. The air exposure constituted an imbalance factor at the ion homeostasis and at the endogenous cholesterol synthesis. Besides, the recovery time did not result in the complete physiological rehabilitation face the imposed challenge.

“…Os esfregaços de P. mesopotamicus evidenciaram maior freqüência de trombócitos, à semelhança do que ocorre em Lepomis macrochirus Raf (MURRA Y 1984), em Gudusia chapra (Clupeidae) (CHONDAR (982) e em Sarotherodon melanotheron (Cichlidae) (LEA MASTER et a!. 1990).…”

ABSTRACT. Hematological charactcristics of Brazilian tcleosts. II. Blood parameters of Piaractus mesopotamicus Holmberg (Osteichthyes, Characidae) in an intensive polycuIture system. Hematological parameters offreshwater fishPiaraclus mesopotamicus (Holmberg, 1887) kept in an intensive polyculture system were detelmined. The cOlTelations among these parameters as well as those between the parameters and the biometric data (total weight and standard length) were also analyzed. Erythrocytes count was l. 708±0.42 x 10 6 /J.lI, hemoglobin 6.6±2.0 g% of blood and hematocrit 32.5±4.6%, mean corpuscular volume (MCV) 209.8±69.5%, mean corpuscular hemoglobin (MCH) 40.2±5.6 pg and mean corpuscular hemoglobin concentration (MCHC) 2l.4±8.4%. The percentage of defense blood cells including leucocytes and thrombocytes, was studied . The percentage of thrombocytes was 61.4±10.0%, Iymphocytes 21.7±1.8%, neutrophils 10.4±11.0%, monocytes 4.7±3.3% and special granulocitic cells 1.8±2.0%. The number of erythrocytes was positively cOlTelated with the hemoglobin rate and negatively correlated with MVC. Hemoglobin was positively correlated with MCHC whereas hematocrit was negatively correlated with MCHC and MVC. Contrarily, leukocytes did not show correlations among themselves or with the hematological parameters and biometric data. KEY WORDS .

“…II y a des différences entre espèces (Wedemeyer et Chatterton, 1970;Sandnes et al, 1988;Leamaster et al, 1990) Comme l'ont indiqué de nombreux auteurs (Barnhart, 1969 ;Kaushik et Luquet, 1979 ;Shimma et al, 1982 ;Alexis et al, 1986;Lemaire et al, 1991), I'alimentation pourrait être impliquée dans la variation de ce paramètre. Néanmoins, il est difficile d'expliquer les écarts observés entre le brochet et les Percidés qui ont un régime alimentaire semblable.…”

Recherches sur l'état physiologique des poissons de la retenue de Pareloup : données relatives à cinq années d'étude

et al. 1994

Résumé. -L'état physiologique des poissons a été estimé, pour une part, par l'évaluation mensuelle, au cours de quatre années (1984, 1989, 1990, 1991), de caractéristiques morphophysiologiques et de la composition somatique chez deux espèces différant par leur régime alimentaire : la perche et le gardon. Les valeurs obtenues ont démontré qu'il y a certaines années (1984, 1989), en été, un ralentissement de la croissance pondérale, une diminution ou un arrêt de l'accrétion protéique accompagné d'une modification de la concentration d'acides aminés ainsi qu'une chute de la teneur en lipides somatiques. Ces résultats indiquent nettement l'existence, dans la retenue de Pareloup, de conditions nutritionnelles plus ou moins favorables aux populations pisciaires, durant la période estivale. Par ailleurs, la détermination de paramètres sanguins, au cours d'un cycle annuel (1992)(1993), chez plusieurs espèces de poissons (brème, chevesne, brochet, sandre, perche) a révélé que si la valeur de l'hématocrite, la cholestérolémie, la triglycéridémie et la protéinémie sont, d'une manière générale, relativement stables, la glycémie varierait avec la photopériode et le taux d'insuline circulante serait en relation avec le cycle sexuel, pour la plupart des espèces.Mots-clés. -Poissons, retenue, composition somatique, paramètres sanguins.Abstract. -The physiological state of fish was first assessed by monthly evaluation in four years (1 984, 1989, 1990, 1991) of certain morphophysiological characteristics and of somatic composition in two species (perch and roach) with different dietary habits. In 1984 and 1989, a slowing down in weight gain, a decrease or an interruption in protein accretion associated with changes in amino acid contents, and a fall in somatic lipid levels were observed in summer. These results clearly point to dietary conditions 258 F. Vellas et al.in Pareloup Reservoir which are more or less favorable to fish populations during this period. In addition, blood parameter rneasurernents, carried out frorn 1992 to 1993 in various fish species (bream, chub, pike, pike-perch, perch), generally showed relatively unchanged values for hematocrit and plasma cholesterol, triglyceride and protein contents, while plasma glucose levels appeared dependent on the photoperiod and circulating insulin rates on the reproductive cycle, for most species.
