“…The values observed in the treated fish were within the normal range of haematocrit for African Catfish as reported by some workers [40,41] that normal values were usually range between 20% and 35% and rarely attain greater than 50%. These values observed were also within the range reported by some researchers [42] for Heterobranchus longifillis young adults raised in Umudike, South East, Nigeria.…”

Haematological components of blood are valuable in monitoring feed toxicity in cultured fish. The haematological and serum protein of the African Catfish (Clarias gariepinus) juvenile of both sex (n=84, mean weight 117.3 ± 1.57 g; mean length 26.70 ± 0.26 cm) fed with varying dietary inclusions level of Chromolaena odorata (Siam weed) as feed additives for 42 days were determined. Four iso-nitrogenous (35% crude protein) and nearly iso-caloric aqua feed were formulated with the locally sourced feed ingredients with C. odorata leaf powder introduced into the diets at graduated levels of 0.0% (control), 0.5%, 1.0% and 3.0% respectively. At the end of the feeding trial, blood samples were collected from three fish randomly selected from each replicate of the groups. Blood parameters such as red blood cell count (RBC), white blood cells count (WBC), lymphocytes, haematocrit, hemoglobin, mean cell volume (MCV), mean cell haemoglobin (MCH) mean cell haemoglobin concentration (MCHC), plasma protein, albumin, globulin, A-G ratio and cholesterol were estimated. Statistical analysis revealed that these parameters were marginally different (P>0.05) within the groups except WBC that were significantly lower (P<0.05) in treated groups compared with the control. However the values recorded for the parameters in all the groups were within haematological values recommended for cultured African Catfish. This suggests that the leaf powder of Chromolaena odorata fed as feed additives may be safe and non-toxic at low inclusion rates of 0.5-3.0% and had no negative impact on the health status of the African Catfish.

“…However, the mean PCV of cat fish from the present study was at the lower limit which may be attributed to effect of heavy metal concentration in the fish. The RBC and Hb of cat fish from Kwalkwalawa river in this study were lower than the reference values for cat fish as reported by (Adeyemo et al, 2014;Okorie-Kanu and Unakalamba, 2015). This agrees with the findings of Khan et al (2020) and Tabrez et al (2021) where heavy metals accumulation in fish caused significant decreases in Hb, PCV and RBC.…”

Fish is a cheap source of omega- 3 polyunsaturated fatty acids for humans. However, the presence of toxic heavy metals in water can be detrimental to both fish and humans. The aim of this study was to investigate the levels of heavy metals in the liver, kidney and gills of cat fish obtained from Kwalkwalawa River, Sokoto. Water, sediments, blood and tissue samples of (10) cat fish (Clarias gariepinus) species caught from Kwalkwalawa river were analysed quantitatively for the presence of zinc, copper, lead, chromium and cadmium using atomic absorption spectrophotometer. Bioaccumulation of these heavy metals was estimated in these organs. Results showed that lead concentrations in the water was significantly higher (p < 0.05) compared to the sediment sample. Also, copper and lead accumulated most in the liver and kidney when compared with that observed for the gills. In conclusion, lead and cadmium levels in the samples were above WHO certified limits hence the concentration of metals in this water should be monitored periodically.

Abstract. A 56-day feeding trial was conducted to evaluate the effect of processing time, inclusion level and/or their interactions on serum biochemistry, haematology and histology of the liver and kidney of Clarias gariepinus fed diets containing Luffa cylindrica seedmeal. The five formulated diets were designated as control (CTR) and tested, replaced at 15 and 30% by 5- and 10-min toasted Luffa cylindrica seedmeal (D515T, D530T, D1015T and D1030T). The experimental design followed a 2×2 factorial experiment in a completely randomised design; the processing time of 5- and 10-min toasting and inclusion level of 15 and 30% serves as factors. Triplicate groups of each treatment were made. Blood sampling, harvesting of organs, serum biochemistry, histology and haematological studies followed standard procedures. The results of the study showed that the effect of processing time, inclusion level and their interactions had significant impact (p<0.05) on Clarias gariepinus. A decrease in RBC, PCV and Hb was observed when compared with control for inclusion level, processing time and/or their interaction. Total protein, albumin and globulin of the blood of fish fed diet CTR was not significantly different (p>0.05) from that of the blood of the fish fed D1015T. Mild to moderate vacuolation of the hepatocytes were recorded among the livers of fish fed control and test dietary treatments except those fed D1030T that recorded very severe vacuolation of the hepatocytes. The kidney, being the excretory organ, was also affected. However, normal cell architecture was recorded in fish fed CTR, D530T and D1030T.
