| Juvenile hybrid tilapia (Oreochromis niloticus x O.aureus) were held in 1000 l fiberglass tanks at 27 ºC supplied with a filter and an aeration system. Garlic (Allium sativum) was incorporated into diets (0 %, 0.5 % and 1 %) of juvenile hybrid tilapia, O. niloticus x O. aureus (25.5 ± 1.0 g). Non-specific cellular and humoral responses were evaluated at the beginning and after 2-4 weeks. Total leucocyte count, respiratory burst, phagyctic activity, phagocytic index and lysozyme activity were enhanced in garlic 0.5 % treated groups compared to the control group after 4 weeks. Fish fed with garlic supplemented diets at 0.5 % and 1 % did not exhibit any improvement in growth as compared to those fed with control diet after 2-4 weeks. It is concluded that... |

| Mozambique tilapia Oreochromis mossambicus acclimated to 27 °C were then held at 19, 23, 27 (control), 31 and 35 °C, and were examined for non-specific cellular and humoral responses after 12–96 h. Total leucocyte count decreased significantly when fish were transferred to 19 and 23 °C after 48 and 96 h, and when transferred to 35 °C over 12–96 h, respectively. Respiratory burst decreased significantly when fish were transferred to 19, 31 and 35 °C over 24–96 h, whereas phagocytic activity and phagocytic index decreased significantly when fish were transferred to low temperatures (19 and 23 °C) and high temperatures (31 and 35 °C) over 12–96 h. Lysozyme activity decreased significantly when fish were transferred to 19 °C after 12–96 h, but increased... |
