Hematological parameters in Nile Tilápia, Oreochromis niloticus exposed to sub-letal concentrations of mercury

Abstract

Mercury toxicity in tilapia, Oreochromis niloticus, (Linnaeus, 1758)

Effect of Stressors on Haematological and Hormonal Parameters of Garra gotyla gotyla

“…Further increase observed in neutrophils and thrombocytes (starved fishes) and in monocytes and eosinophils (metal treated) may be in view of the fact that monocytes, eosinophils and basophils (starved fishes) and neutrophils, basophils and thrombocytes (metal treated) which too are the other members of phagocytic machinery in starved and metal treated groups show a dip under the stress of starvation and metal toxicity. Mahajan and Dheer (1979), Ishikawa et al, (2007) and Devi et al, (2008) also reported such changes in number of agranulocytes and granulocytes under the stress of starvation and metal toxicity.…”

Effects of <i>Alpinia galanga</i> oil on anesthesia and stress reduction in <i>Oreochromis niloticus </i>

“…The recommended dose of MS-222 on Nile tilapia was 130 mg/L (4) while the suitable dose of AGO was 700 mg/L. Generally, the hematological parameters; Hb, Hct, RBC, and WBC of resting fish are approximately 6 g/dL, 26%, 1 × 10 6 cells/µL, and 15 × 10 3 cells/µL, respectively (44,45). In the present study, the hematological parameters of anesthetized Nile tilapia with AGO and MS-222 were higher than the normal level.…”

Comparative Study of Toxicological Impinge of Glyphosate and Atrazine (Herbicide) on Stress Biomarkers; Blood Biochemical and Hematological Parameters of the Freshwater Common Carp (Cyprinus carpio)

“…An increase in platelets concentrations against glyphosate was noticed, as was a decline in concentrations against atrazine. [43] found that platelets exhibit significant increases in their number in zinc-treated fish. It should be mentioned that increases in thrombocytes or platelets in treated fish can cause the arrest of any sort of internal bleeding.…”

“…Exposure of fish to sub-lethal concentrations of copper for 15, 30, and 45 days caused significant alterations in hematological parameters of the Indian freshwater fish Channa punctatus, and WBC counts in their work were found to significantly increase as compared to control [42]. High white blood cell counts indicate damage due to infection of body tissues, severe physical stress, and leukemia [43][44].…”
