“…However, the very high salinity concentration for the river samples is because they are seawater in origin while the lower values may be due to dilution as confirmed by McLusky [28] that rainfall is capable of causing dilution of estuaries thereby resulting in salinity reduction while evaporation will result in increase salinity. Akinrotim et al [29] in their study further confirmed that the highest values (16.18-21.11%) were recorded during the dry months while sampling the Buguma Creek.…”

Aims: The hand-dug wells and river water in Oproama Community, Rivers State, Nigeria was assessed for its quality. Study Design: The study involved ten (10) sampling stations consisting of seven (7) hand-dug wells and three (3) points along the Oproama River. Place and Duration of Study: Oproama Community in Asari-toru Local Government Area of Rivers State, Nigeria between January and December, 2011 to cover both dry and wet seasons. Methodology: The parameters assessed were Vibrio (bacteria), salinity, calcium, magnesium concentrations as well as saltwater intrusion status employing standard laboratory procedures and estimation model. Results: The results reveal that Vibrio counts ranged from 2 x102 to 1.375 x104 cfu/100ml and the bacteria species identified from the water sources were Vibrio cholera and Vibrio parahaemolyticus. The study also reveals that salinity ranged from 11.97 to 13,772mg/l, calcium, 0.15 to 126.33mg/l and magnesium, 0.09 to 43.02mg/l. All parameters assessed exhibited seasonal variation during the study period; Calcium/magnesium (Ca/Mg) ratios for each well water sample ranged from 1.67 to 12.33 and indicate absence of saltwater intrusion which stands at a Ca/Mg limit of 1. Conclusion: Salinity (particularly well water samples), calcium and magnesium concentrations were within recommended limit; Vibrio counts were high and its presence in drinking water has public health risk; therefore, the use of sanitary buckets and point-of-use (households use) treatment and safe storage practices of water is strongly advocated.

“…The result of Monocytes value in brackish water T. zillii in this research was lower than those studied by Martins et al (2008) in Nile tilapia (14.3±7.7) and Tilapia guineensis (3.12±1.01) by Akinrotimi et al (2010). High Monocytes could be explained by the increase in reproductive activity and defense mechanism of fish (Orun and Erdemli, 2003).…”

“…This work shows a decrease in lymphocytes in T. zillii Brackish water contrarily to that observed in T. zillii (74.4±2.13) by Ghazaly (1992). However, these values were higher than the values obtained for Nile tilapia (20.5±9.7) by Martins et al (2008), and values of Tilapia guineensis (35.46±4.11) by Akinrotimi et al (2010).…”

Hematology can be a useful tool for monitoring health status, detecting illness, and following the progress of disease and response to therapy. Despite advances in fish medicine in recent years, interpretation of fish hematology often is hampered by a lack of meaningful reference values and the bewildering diversity of fish species. Hematology is the science of studying the anatomical, physiological, and pathological aspects of blood. This study gives valuable information on fish Tilapia zillii, Hematological indices (RBC, WBC, Hct, Hb, MCV, MCH, MCHC, GRA, MON, LYM, and PLT) were measured in blood in samples from 30 adult fish captured from (Ain Elmajdob lake), Benghazi city. Statistical analysis revealed that white blood cells were found depending on the length and weight of Tilapia zillii as studied by regression of white blood cells on length and weight of Tilapia zillii. Moreover, Lymphocytes and Monocytes increased with the increase in weight, as studied by regression of Lymphocytes and Monocytes on the length and weight of Tilapia zillii. Nevertheless, not significant in Red blood cells, Hemoglobin, Haematocrit, Mean corpuscular volume, Mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and platelets.

Background and Aim: The intensive nature of aquaculture has subjected fish to a number of stressors in the culture medium, anesthetics are widely used to minimize the issue of stress during farming operations and activities. Clove oil is a well known, established and acceptable anesthetics commonly used in aquaculture, this anesthetics is not readily available in developing countries, thus leaving the fish farmers with option of using the locally available plant extracts as anesthetic agent in fish culture. This study therefore assessed the efficacy of aqueous extracts of clove seed and its effect on hematological parameters of the fish.Methods: A total of 300 Clarias gariepinus comprises of 150 juveniles and 150 adult fish were exposed in triplicates to aqueous extracts of clove seed at concentrations of 5.0, 10.0, 15.0, 20.0 and 25.0mg/l at the rate of 10 fish per tank for both juveniles and adult fish. Induction time (Time taken for the fish to be completely anaesthetized) and recovery time (Time taken for the fish to resume normal swimming) was monitored using stop watch. Also, the effect of the extracts on water quality, survival and hematological parameters of the fish were evaluated using standard methods. Results:The result obtained revealed that the induction time indicated a size related response with the adult fish significantly (P<0.05) higher than the juveniles at all concentration of exposure. However, reverse was the case in recovery time, as the recover times in juveniles were higher than the adult fish. The survival was 100% in both sizes. Significant alterations were recorded in the haematological variables of the fish, which was more pronounced at higher concentrations of the extracts.
