“…The absence or scarcity of fish blood basophils has been widely noted (Drezwina, 1911;Werzberg, 1911;Jordan, 1938;Saunders, 1966;Weinberg et al, 1972), they being described as cells containing a blue-stained nucleus and large magenta-stained granules (Jordan, 1926). We have not found basophils in S. aurata blood smears.…”

The peripheral blood cells of the gilthead seabream (Sparus aurata L.) were studied by light and transmission and scanning electron microscopic methods. Acidophilic erythroblasts and mature erythrocytes, round, oval, and fusiform thrombocytes, neutrophils, acidophils and basophils, lymphocytes, plasma cells, and monocyte-macrophages were characterized. A comparison of our light and electron microscopic results was carried out. The results were discussed with those for other fish species and the main modifications from the common vertebrate haematological pattern observed being considered.

“…1972; Sherburne 1974; Murray 1984), although they have been observed in others (Romestand and Trilles 1984; Zuasti and Ferrer 1988). In the HK of the O. niloticus we identified some developing cells of the basophilic series (myelocyte and metamyelocyte) characterised by prominent rER and large, rounded cytoplasmic granules with fibrillary content as mentioned in Sparus aurata (Zuasti and Ferrer 1988).…”

The present work focused on the histological and ultrastructural studies on haemopoiesis in the kidney of tilapia, Oreochromis niloticus. Haemopoietic tissue was found mainly in the head kidney and a small amount occurred in the mesonephros. The haemopoiesis of tilapia had the following series: erythropoiesis, granulopoiesis, thrombopoiesis, monopoiesis and lymphoplasmopoiesis. Erythropoiesis includes proerythroblasts, basophilic erythroblasts, polychromatic erythroblasts, acidophilic erythroblasts and young and mature erythrocytes. The proerythroblasts were the largest cells in the erythropoietic series. During the maturation process both the nuclear and cellular size decreased gradually due to the chromatin condensation and the progressive substitution of cytoplasmic matrix with a large amount of haemoglobin. Granulopoietic series consisted of cells with variable shape and size at different stages of maturity from myeloblasts to mature granulocytes. The promyelocytes were the largest cells in the series and were characterised by the appearance of primary (azoruphilic) granules. The maturation process involved the appearance of specific granules in the heterophilic, eosinophilic and basophilic series. It is important to mention that eosinophilic granulocytes were the dominant granulopoietic series in the haemopoietic tissue (Ht) of tilapia. Lymphopoietic series consisted of lymphoblasts, large lymphocytes, small lymphocytes and active and inactive plasma cells. Thrombopoietic series consisted of thromboblasts, prothromboblasts and thrombocytes. Thrombocytes of tilapia were nucleated and possessed a spindle shape. Melanomacrophage centres were dominant among the Ht of the head kidney. Also, monocytes were detected and shown to be large cells with an indented nucleus and cytoplasm containing numerous vesicles of different sizes and a few lysosomes.

Different fasting and re-feeding cycles were tested in a 60-day trial in sobaity sea bream (Sparidentex hasta) juveniles to evaluate their effects on growth, physiological and biochemical parameters. Fish were exposed in triplicate to the following feeding regimes: control (fed everyday); F-RF 1+1 (1 day of starvation followed by 1 day of re-feeding); F-RF 2+2 (2 days of starvation followed by 2 days of re-feeding); F-RF 3+3 (3 days of starvation followed by 3 days of re-feeding); F-RF 6+6 (6 days of starvation followed by 6 days of re-feeding); and F-RF 1+2 (1 day of starvation followed by 2 days of re-feeding). A reduction in body mass between 10.0% (F-RF 1+1 ) and 24.3% (F-RF 6+6 ) was found in comparison with the control group after 60 days. As the length of fasting increased, the compensation coefficients in feed intake and weight gain decreased. Body lipid content decreased as fasting cycles increased. Haemoglobin, plasma protein, lysozyme and alkaline phosphatase activities were the most reliable biomarkers for assessing the nutritional condition in sobaity sea bream. A feeding strategy based on 1 day of starvation followed by 2 days of re-feeding (F-RF 1+2 group) may be advisable for on-growing sobaity sea bream without reduction in growth and alteration of their haematological and physiological parameters.
