“…Haematological and plasma values of the gilthead seabream obtained here could only be compared with other species, since no data were found in the literature for this species. Consequently, the data obtained in this study could be useful as reference values for further studies, although comparisons must be taken with caution because, as has been well established, remarkable differences can be obtained depending on sampling methods (Hoffmann et al, 1982;Korcock et al, 1988;Barham & Schoonbee, 1991) and seasonal or environmental conditions (Van Vuren & Hattingh, 1978;Lochmiller et al, 1989;LeaMaster et al, 1990).…”

Haematological and haemorheological responses against a moderate management stress, applied for 2 weeks, have been studied in the gilthead seabream (Sparus aurata). The stress application leads to a significant reduction in circulating erythrocytes, which caused decreased blood viscosity. Although erythrocyte osmotic fragility showed a trend inversely related to the duration of management stress, no significant change in cell dimensions, aggregation and deformation indices was observed. Consequently, the decrease in oxygen transport capacity attributable to haematocrit reduction, is not compensated by a qualitative change in the microrheological behaviour of erythrocytes, since the blood viscosity decreases as a direct result of the decline in red blood cell number.
