          Abstract

          Se realizó una evaluación hematológica y de bioquímica sanguínea en 10 especies de peces marinos en la bahía del Callao, Perú, en las cuatro estaciones del año y en cuatro áreas de muestreo con diferentes grados de perturbación antrópica. Las especies fueron: «lorna» Sciaena deliciosa (Tschudi, 1846) (Sciaenidae), «lisa» Mugil cephalus Linnaeus, 1758 (Mugilidae), «pejerrey» Odontesthes regia (Humboldt, 1821) (Atherinidae), «pintadilla» Cheilodactylus variegatus Valenciennes, 1833 (Cheilodactylidae), «tramboyo» Labrisomus philippii (Steindachner, 1866) (Labrisomidae), «borrachito» Scartichthys gigas Steindachner, 1876 (Blenniidae), «mojarrilla» Stellifer minor (Tschudi, 1846) (Sciaenidae), «machete» Ethmidium maculatum (Valenciennes, 1847) (Clupeidae), «cavinza» Isacia conceptionis (Cuvier, 1830) (Haemulidae) y «chiri» Stromateus stellatus Cuvier, 1829 (Stromateidae). Los valores de hematocrito, hemoglobina y triglicéridos fueron significativamente mayores en E. maculatus, S. minor e I. conceptionis. En S. deliciosa solo fue más alta la hemoglobina y en I. conceptionis solo para el colesterol. Los parámetros hematológicos leucocitarios (linfocitos, monocitos, basófilos, eosinófilos y neutrófilos) y el HDL no mostraron variaciones entre las especies, entre estaciones del año ni entre áreas de muestreo. La hemoglobina y colesterol fueron mayores para S. deliciosa y de hematocrito y colesterol para M. cephalus y O. regia en el área del muelle del Callao. Para M. cephalus se notó valores más altos de hematocrito, hemoglobina y colesterol en primavera, y los niveles de colesterol fueron más bajos en el verano para M. cephalus y para O. regia.

          Translated abstract

          A hematological and blood biochemical evaluation was performed on 10 species of marine fish in the bay of Callao, Peru, in the four seasons of the year and in four sampling areas with different degrees of anthropic disturbance. The species of fish were: «lorna» Sciaena deliciosa (Tschudi, 1846) (Sciaenidae), «lisa» Mugil cephalus Linnaeus, 1758 (Mugilidae), «pejerrey» Odontesthes regia (Humboldt, 1821) (Atherinidae), «pintadilla» Cheilodactylus variegatus Valenciennes, 1833 (Cheilodactylidae), «tramboyo» Labrisomus philippii (Steindachner, 1866) (Labrisomidae), «borrachito» Scartichthys gigas Steindachner, 1876 (Blenniidae), «mojarrilla» Stellifer minor (Tschudi, 1846) (Sciaenidae), «machete» Ethmidium maculatum (Valenciennes, 1847) (Clupeidae), «cavinza» Isacia conceptionis (Cuvier, 1830) (Haemulidae) and «chiri» Stromateus stellatus Cuvier, 1829 (Stromateidae). The values of hematocrit, hemoglobin and triglycerides were significantly higher in E. maculatum, S. minor and I. conceptionis. In S. deliciosa only hemoglobin was higher, and in I. conceptionis only for cholesterol. The leukocyte hematological parameters (lymphocytes, monocytes, basophils, eosinophils and neutrophils) and the HDL showed no variations between species, between seasons or between sampling areas. Hemoglobin and cholesterol were higher for S. deliciosa and hematocrit and cholesterol for M. cephalus and O. regia in the Callao pier area. For M. cephalus higher values of hematocrit, hemoglobin and cholesterol were noted in spring, and cholesterol levels were lower in the summer for M. cephalus and for O. regia.

            Characterization of blood cells and hematological parameters in Cichlasoma dimerus (Teleostei, Perciformes).

            The aim of the present study was to obtain a basic knowledge of the hematology of Cichlasoma dimerus. The morphological features of blood cells were described according to the observations made by light and electron microscopy. Erythrocytes, thrombocytes and four types of leucocytes: lymphocytes, monocytes, heterophils and eosinophils, were distinguished and characterized. Thrombocytes are the most abundant blood cells after erythrocytes and are recognized easily from lymphocytes by morphological features and size. Heterophils and eosinophils are PAS positive. Hematological indices (RBC, WBC, PCV, Hb, MCV, MCH, MCHC and leucocyte differential count) were measured in one blood sample from 30 adult fish captured in Esteros del Riachuelo, Corrientes, Argentina (27 degrees 25'S, 58 degrees 15'W). The reference interval and the mean were determined for each hematological parameter evaluated. Contrary to other species, the percent of heterophils was found to be high in relation to the percent of lymphocytes. Low lymphocyte counts occurred in C. dimerus, as compared to these found in other fishes. Compared to most teleosts, this species has similar mean values for PCV and Hb and slightly higher for RBC. Statistical analysis revealed that differences in hematological parameters between male and female fish were not significant.
