“…The pattern of tail beat frequency (TBF) observed in this study has been reported in clariids exposed to various a herbicide (Koffi, 2005). However, it differed from the reports of Bobmanuel et al (2006) and Onusiriuka and Ufodike (1994) possibly due to the modes of action of the toxicants. The abnormal behavioural responses in fish exposed to L. alopecuroides were similar to that earlier reported by a number of authors (Onusiriuka and Ufodike, 1998;Oti, 2002;Koffi, 2005).…”

“…Similar observations were made by Onusiriuka and Ufodike (1994) in acute test solutions of Akee apple, Blighia sapida and sausage plant, Kigelia africana extracts to which C. gariepinus was exposed. Studies have shown that when the water quality is affected by toxicants, physiological changes will be reflected in the values of one or more of the haemotological parameter and swimming activity of fish (Heath, 1991;Adeyemo, 2005).…”

“…Although H. bidorsalis was more susceptible to the piscicide, the rate of mortality was slower than that for C. gariepinus, hence the higher MLT 50 value. Based on the 96hrLC 50 the extract appeared to be more toxic to the fish species in comparism with extracts of Akee apple, Blighia sapida and sausage plant, Kigelia africana (Onusiriuka and Ufodike, 1994;1998), textile effluents (Nwanna et al 2000), cassava effluents (Oti, 2002), insecticide, dimethoate (Auta et al 2004). The toxicity of the extracts had been demonstrated by Obomanu et al (2006) in mosquito larvae, mudskipper (Obomanu et al, 2006), tadpoles (Suleiman, 2006) and Gabriel, et al (2009).…”

“…Ekanem et al (2003) also reported that Asystasia vogeliana (Acanthaceae) is also highly toxic to the embyos of zebra fish, Danio rerio, while Agbon, et al (2002) and Omoniyi, et al (2002) reported the toxicity of Nicotiana tobaccum to Oreochromis niloticus and Clarias gariepinus fingerlings, respectively. Water extracts of the floral and bark of Bligha sapida and Kigelia africana have been reported to be toxic to Clarias gariepinus causing increased opercular and tail beats and mortality (Onusiriuka and Ufodike 1994;. Generally, the stressful behaviours of exposed fishes tend to show feelings of respiratory impairment due to direct damage to the gill epithelia, besides accumulation of mucus which may further aggrevate the problems.…”

“…Results of the regression of OBF on the concentration of the toxicant and time lend credence to the observation and claim by several authors that OBF is better tool for assessing acute toxicity of the plant extract than TBF based on the unit changed in each of these variables with that of the toxicant (Ekweozor et al, 2001;;Bobmanuel et al, 2006). This may explain why several authors prefer the use of obf to tbf in the study of stress responses of fish to the effects of toxicants, (Onusiriuka and Ufodike, 1994;Babatunde et al, 2000;Oti, 2002).…”

This study was carried out to evaluate the use of Lactobacillus acidophilus as a biocontrol agent against some common fish pathogenic bacteria (Staphylococcus xylosus, Aeromonas hydrophila gr.2 and Streptococcus agalactiae) in African catfish, Clarias gariepinus. Eight treatments were designed inclusive of 10 C. gariepinus juveniles (mean weight 190 g) per tank, each in triplicate. Four groups of fish were fed a diet supplemented with L. acidophilus, comprising about 3.01 × 107 colony‐forming units per gram of diet (the probiotics diet), while the other four groups were fed a diet not supplemented with probiotics (the non‐probiotics diet). In the first group, fish were injected with 1 mL physiological saline and fed the non‐probiotic diet (non‐probiotic control); in the second, third and fourth groups, fish were injected with 1 mL each of S. xylosus, A. hydrophila gr.2 and S. agalactiae, respectively, and were all fed the non‐probiotic diet (designated as non‐probiotic treatments; NPsx, NPah and NPsa respectively). In the fifth group, fish were injected with 1 mL physiological saline but fed the probiotic diet (probiotic control), while fish in the sixth, seventh and eighth groups were each injected with 1 mL of S. xylosus, A. hydrophila gr.2 and S. agalactiae, respectively, and were all fed the probiotic diet (and designated as probiotic treatments; Psx, Pah and Psa respectively). Blood samples were collected for haematology analysis, while samples of the liver and kidney were examined for pathohistology after 7 and 21 days of infection. The results showed that the haematology parameters, packed cell volume, haemoglobin, erythrocyte sedimentation rate, red blood cell, white blood cell, total serum protein, Mg2+, Ca2+, Cl−, glucose, cholesterol and total immunoglobulin concentrations and the pathohistology of the liver and kidney were better in the challenged fish (infected) maintained on the probiotic diet than those in the groups fed the non‐probiotic diet. It is concluded, based on these results, that L. acidophilus is useful as a probiotic agent in C. gariepinus against these pathogenic bacteria (S. xylosus, A. hydrophila gr.2 and S. agalactiae).
