This lab scale study aims to investigate the effect of different concentration of waste lubricating oil on the African catfish juveniles, Clarias gariepinus. Five different concentrations of waste lubricating oil were used for 96 hours period which are 0 ml/L, 5 ml/L, 10 ml/l, 15 ml/l, and 20 ml/L. After 96 hours of experiment, tank 4 which being added with 20 mL waste lubricating oil shows the highest percentage of fish mortality (100%) followed by tank 3 (95%), and tank 2 (76%) while the lowest percentage of mortality is recorded in tank 1 (19%). The result from the toxicity test showed that the higher the concentration of waste lubricating oil, the higher the mortality rate of fish.  The lethal concentration LC50 that caused 50% mortality of test fish was estimated at 8.1 ml/L. From the observation, waste lubricating oil which contains heavy metals had cause damage to renal and nervous system of fishes thus causing them to lost equilibrium and irregular vertical swimming that will finally cause death. It can be concluded that the harmful environment that will trigger death of fish will be created by indiscriminate discharge of waste oil into water bodies. Therefore, it is recommended to treat the wastewaters, sewage and industrial wastes before it is being discharged into the aquatic ecosystems to sustain the aquatic species for the future.  The proper effluent treatment technology should be adopted to check the present of oil spillage in the water. The enforcement of laws and legislations related to the protection of aquatic environment must be enhance and take into considerations.

The formulation of glyphosate composed of Isopropylamine salt and Polyethoxylated tallow Amine (Clearweed) is widely used as herbicide to control weeds both in the terrestrial and aquatic environments. A static bioassay was conducted to examine toxicity of this formulation on juvenile African catfish (Clarias gariepinus). Catfish juvenile (mean weight 27.97±0.03g) were exposed to glyphosate at concentrations of 0.00mg/l (control), 5.00, 7.50, 10.00, 12.50 and 15.00mg/l. Each concentration was treated in triplicate and the exposure period lasted for 96 hrs. Mortality rates and physico-chemical parameters of water were monitored. Results revealed that fish mortality increased with increasing concentration of glyphosate and time of exposure. The median lethal concentration (96-hr LC50) value was 8.88mg/l with the upper and lower limits of 9.10mg/l and 7.75mg/l respectively. Behavioural changes observed the treated fish included: erratic swimming, jerky movement, increased opercula and tail movements, gulping of air, lost of balance and consciousness, cessation of opercula and tail movement signifying eventual death. Water quality parameters increased significantly (p<0.05) with extract concentration except dissolve oxygen levels which reduced (p<0.05). However, all values reported were within the permissible limits of the Federal Ministry of Environment (FMEnv) for water samples. The results of this study indicated that glyphosate formulation has toxic effects on catfish. Thus, the herbicide should be cautiously used to avoid ecotoxicological hazards particularly on non-target organisms.

Toxicity of cadmium to all lives especially the aquatic life cannot be quantified due to their deleterious effect usually caused as a result of their incessant and uncontrollable discharged into the aquatic environment. The present study was undertaken to assess the effect of cadmium and Hibiscus Sabdariffa Calyx Extract on the Organ Gravimetry and Lipid Profile of the Liver and Serum of African Catfish (Clarias gariepinus). Forty juvenile catfish were divided into four groups containing ten fish with average weight 170 ± 2kg per group [Group A, Control (–HSCE – Cd), Group B (+HSCE), Group C (+Cd) and Group D (+HSCE + Cd)]. Group B and D were administered a daily dose of 40ml/kg body weight of Hibiscus sabdariffa calyx extracts (HSCE) (0.25%v/v) for 14 days while groups C and D were exposed to the same dose containing 0.3 mg of Cd/L daily for 14 days. The result shows that there was significant decrease (p<0.05) in the liver total- and LDL- cholesterol of fish exposed to HSCE and HSCE + Cd treated groups when compared to control and cadmium treated group. The triglycerides concentration of liver and serum was significantly increased (p<0.05) in fish exposed to cadmium when compared to the control and HSCE + Cd treated group respectively. SOD activity was significantly increase (p<0.05) in the serum of catfish exposed to Cd when compared to control. However, the liver-body weight ratio was significantly decreased in Cd and Cd + HSCE treated groups relative to the control. It is evident from the result obtained in this study that HSCE has protective effect against cadmium intoxicated fish (Clarias gariepinus).

Aquatic pollution caused by industrial effluents is an environmental issue, imposing deleterious impacts on the overall environment, specifically, on humans, by disrupting the balance of the ecosystem. Among all the industries, tanneries are considered some of the most polluting due to heavy use of toxic organic and inorganic compounds during leather processing, most of which find their way into rivers, lakes, and streams, thus exerting adverse effects on aquatic life, particularly on fish. Considering the huge concentrations of pollutants present in tannery effluents, toxicity evaluation is of prime importance. Therefore, bioassays are usually employed to assess the acute toxicity of industrial effluents and efficiency of effluent clean-up technologies as they provide a thorough response of test species to the substances present in the tested media. In the present study, the toxic effects of tannery effluent on common grass carp (Ctenopharyngodon idella) were studied for 96 h in laboratory conditions. The effluent was added at different concentrations, before and after treatment by constructed wetlands (CWs). During this period, mortality data was collected to calculate the 96 h-LC50 (lethal concentration inducing 50% mortality) and acute toxicity of C. idella. In addition to this, observations on change in morphological, physiological, and behavioural patterns were also made every 24 h. The present toxicity assay revealed that the raw tannery effluent changed the morphology, physiology, and behavioural response of fish. Moreover, fish exposure to raw/untreated effluent caused high acute toxicity and 100% mortality, due to the presence of high concentrations of salts and chromium (Cr) metal. While treatment of tannery effluent by CWs vegetated with different plants (B. mutica, L. fusca, and T. domingensis) significantly reduced its toxicity and fish mortality as well, and inoculation of salt and Cr-tolerant endophytic bacteria (Enterobacter sp. HU38, Microbacterium arborescens HU33, and Pantoea stewartii ASI11) further reduced (up to 90%) its toxicity level. Hence, the use of CWs for tannery effluent treatment can be recommended to favour public health and promote the overall safety of the environment.

The aquatic ecosystem is under increasing pressure from environmental contaminants due to anthropogenic activities. This study investigated the potential of glyphosate and paraquat to induce DNA damage and other cell abnormalities in juvenile African Catfish, Clarias gariepinus. Juvenile fish were exposed for 96 h to 0.36, 0.48, 0.60, 0.72 and 0.84 mg/L glyphosate; and 0.018, 0.037, 0.055, 0.110 and 0.221 mg/L paraquat. Following the exposure, the fish liver and blood were analysed for DNA damage and micronucleus respectively. DNA damage was analysed using comet assay while the micronucleus test was used for assessing nuclear abnormalities. Both herbicides induced DNA damage in fish, with paraquat exhibiting higher toxicity. The severity in liver DNA damage was observed to be dependent on concentration. The herbicides triggered formation of micronuclei, bean-shaped cells, lobed nuclei, and apoptosis in blood cells of fish. Both herbicides also increased the frequency of occurrence of these cell abnormalities in erythrocytes and showed mutagenic potential in fish. Glyphosate and Paraquat both have mutagenic potentials in fish and this is a reflection of the threat these contaminants pose to fish and other forms of aquatic life in our natural water bodies. Low concentrations of these herbicides should be encouraged when usage is inevitable

The Impact

Background and Objectives: The study measured the impact of crude oil fractions and its derivatives like kerosene on the early life and sub-adults growth of African catfish, Clarias gariepinus in terms of mild, acute and chronic toxicity effect. It also examines the effect of indiscriminate spillage of crude oil derivatives on aquatic organisms.  Materials and Methods: Blood profiles such as Red Blood Cell count (RBC), White Blood Cell count (WBC), Blood Differentials, Hemoglobin, (HB), and Packed Cell Volume (PCV) of the treated fishes and control were estimated after exposure of the fish to the kerosene pollutant. Behavioral changes in fish exposed to8.0ml/l, 16.0ml/l, 25.0ml/l and 50.0ml/l of kerosene pollutant varied from erratic swimming, moribund movement, jumping and lack of balance. Results: At concentration 8.0ml/L, mean total mortality was observed within 72hours of exposure. The lethal concentration (LC50) was 8.0ml/L and highest mean mortality observed with 80% kerosene pollutant. PCV of the exposed fish was 26% when compared to the control 27%, HB was 8.9 gdl as against 9.0 gdl in the control. Total WBC was 640 x 109/L as against 1280 x 109/L in control. RBC reading was 2.1 compared to 5.3 mm3 of the control.  Lymphocyte was 80%, Neutrophil was 4% and monocyte 16% compared to 62%, 8% and 30% in control respectively. There was decrease in white blood cells counts for 8.0, 16.0, 25.0 and 50.0ml/L groups (p<0.05) compared to the control. Conclusion: The study concludes that it is necessary to ensure the safety of aquatic life forms especially fishes, by minimizing aquatic pollution with kerosene to sustain fish food quality, availability and security.

The contamination of aquatic ecosystem with heavy metals and pesticides has increased dramatically over the years, and this has generated a lot of attention by environmental experts. There are reports on impacts of different single toxicants on aquatic organisms but not much has been done to investigate the impacts of mixtures of toxicants on aquatic life. In this study we investigated the effects of multiple stressors of Pb and cypermethrin on ionoregulation in the African catfish (Clarias gariepinus). Adults C. gariepinus were exposed to either borehole water (control), 2 mg/L Pb, 0.5 μg/L cypermetrin or a mixture of 2 mg/L Pb and 0.5 μg/L cypermethrin for 96 h, after which the levels of plasma Na+, Cl- and K+ were determined as a measure of branchial ionoregulatory disturbance. The exposure of C. gariepinus to 0.5 μg/L cypermethrin resulted in a significant reduction in plasma Na+ (43% decrease) and Cl- (31% decrease) but a 2-fold increase in plasma K+ concentrations. Exposure to a mixture of cypermethrin and Pb resulted in 53% decrease in plasma Na+, 40% decrease in plasma Cl- and a 3- fold increase in plasma K+. There was no significant difference between the control and those exposed to just only 2 mg/L Pb for all the parameters measured. The results of this study indicated that exposure of aquatic organisms to combined stressors of heavy metals pollution as well as pesticide contamination could have a serious effect on the physiology especially on ionic regulation in the exposed fish.

Background: Illicit disposal of scraped out endocarp of bottle gourds as part of processing activity for domestic use into the aquatic environment pose a big threat to the aquatic ecosystem. This study investigated the toxicity effects of crude fruit endocarp extracts of L. siceraria on C. gariepinus juveniles. Methodology: 120 mixed sex of C. gariepinus juveniles of mean weight and length (19.59 ±0.42 g; 14.6 ±0.80 cm) respectively were investigated. The fish were divided into 6 groups of 10 fish in each aquarium containing 5, 20, 35, 50 and 65 mg/L concentration of aqueous extract of L. siceraria and 0.00 mg/L (control) respectively with replicates for Four (4) days for acute toxicity analysis. The animals were sacrificed and blood samples collected for biochemical and isolation of the gills and liver for histopathological studies. Results: Experimental media pH, free carbon (iv) oxide, total alkalinity contents increased while dissolved oxygen decreased significantly (P<0.05) with increase in concentration in the acute bioassay. Temperature did not differ significantly (P>0.05) in all the groups thus, did not affect fish survival. Furthermore, AST, ALT and LDH profiles in blood serum of fish exposed to acute concentrations exhibited a significant increase (P<0.05) with increase in concentration. The exposed gills revealed progressive striking histological alterations viz. thickening and shortening of secondary lamellae, degeneration of connective tissue and complete loss of secondary lamella while the liver showed progressive histo-architectural distortions such as hepatic hypertrophy, cellular degeneration (necrosis), haemorrhage and intracellular infiltration with increase in concentration of the L. siceraria extract. Conclusion: Aqueous extract of L. siceraria had adverse effect on juveniles of C. gariepinus, as evident in the negative modification of the body physiology via biochemical and histological investigations, thus toxic to the aquatic life. Further investigations on other vital organs - kidney, heart, GIT and the reproductive organs are recommended.

This study used a static bioassay to investigate the histological effects of glyphosate on the gill, liver and muscle of African catfish (Clarias gariepinus) fingerlings. This was done with a view of further characterising the effect of glyphosate on C. gariepinus fingerlings and other aquatic life forms. Six-week old C. gariepinus fingerlings with an average weight of 10.02 ± 0.2 g were stocked into three exposure sets (control, 2.75 ppm (25% of the 96 h LC50 value) and 5.50 ppm (50% of the 96 h LC50 value)) in triplicate at 30 fish per tank for 70 days. The 96 h LC50  value was 11.00 mg/L. Histological examination of the C. gariepinus exposed to various sublethal concentrations of glyphosate showed that major histological changes in their organs were concentration dependent such as gill arch vacuolation, excessive mucosal secretions, lifting of epithelial, and epithelium thickening, hyperplasia and telangiectasis in the gills, discolouration, change in form and consistent alterations involving hyperplasia, narrowing of the central nerve, necrosis, pkynosis, blood congestion and vacuolation of the liver, mild hyperplasia and inflammatory responses in the muscle of the fish. The severity of histological alteration was more pronounced in fish organs exposed to 5.50 ppm of glyphosate concentration. This study concluded that the toxicant (glyphosate) is highly toxic to C. gariepinus particularly at a concentration of 5.50 ppm, therefore its use near farm lands or adjacent water bodies should be discouraged.
