“…Haphazard response and cessation of TBF before OBF, and subsequent death may indicate the trend in available metabolic energy. This appears to be the usual trend in the responses of C. gariepinus to acute concentrations of toxicants [33].…”

One hundred and eighty (180) mudskipper (Periophthalmus papilio) of equal size (mean length 18.74 ± 2.64cm and mean weight 156.68 ± 1.81g) were exposed to different concentrations (0.0mg/l-control, 5.0, 10.0, 15.0, 20.0 and 25.0mg/l) of sodium bromide a biocide, to determine the Behavioural responses of opercula beat frequency (OBF), tail beat frequency (TBF), 96 hour lethal concentration (96h.LC 50 and median lethal time (MLT 50). The result obtained indicated that P. papilio showed initial stress responses such as increased opercula ventilator rate, erratic swimming and gasping for air. The pattern of response of TBF to time and concentrations of the biocide was irregular, whereas that of OBF tended to decrease with increase in time, but increased with increase in concentrations. Also cumulative mortality values increased with exposure time and concentrations.

“…Protein attributes the general metabolism and good health of fish; so, enhancement of protein (PRO) in different tissues of animals is clearly determined by the process of balancing between synthesis of protein and its gradual degradation [28] . Total protein content (mgg -1 ) in different tissues under two different experimental sets, such as control, treatment in breeding and dry season (CB & CD and TB & TD) varied significantly in the present study with the higher elevation in TB than in TD compared to CB & CD, specifically, it showed highest value in TB and lowest in CD in intestine, liver, muscle and brain of C. catla, L. rohita, A. testudineus and C. batracus.…”

The present study deals with the impact of choline chloride supplementation, applied directly into the pond water in a semi-intensive farm culture system for 90 d on two Indian Major Carps (IMCs) (Catla catla, Labeo rohita) and two air-breathing teleostean fishes (Anabas testudineus, Clarias batracus).The experiment was conducted in two seasons (breeding and dry) under choline (treated) and non-choline (control) exposure. Biochemical parameters, viz., PRO (total protein) content gained maximum significantly (p< 0.01) in treated-breeding with the lowest in control-dry in intestine, liver, muscle, brain. IMCs showed significant (p< 0.01) increased amylase activity in the liver and intestine in treated-dry and treatment-breeding conditions, while liver amylase activity in both the seasons increased manifolds significantly (p< 0.01) in air-breathing fishes, showing a sharp decline only in the intestine. Protease and lipase activity in the intestine and liver of choline-fed fishes disclosed declining trend in the breeding season significantly (p< 0.01), but treated (choline-fed) IMCs under dry revealed the significant (p< 0.01) increasing and decreasing trend of protease and lipase activity respectively; the reverse trend at dry season was found in air-breathing fishes under choline-fed condition. ALP (alkaline phosphatase) in intestine indicated significant (p< 0.01) lowest activity in treatment-breeding, highest in treatment-dry. This study explored the higher activity towards total protein generation, especially muscle; higher carbohydrate digestion; elevated lipid digestion in choline-fed fishes. So, the fishes from this farm-based pisciculture system are healthy and its yield can be prescribed as a rich source of quality fish food for human health.

Urban effluent discharges as causes of public and environmental health concerns in South Africa’s aquatic milieu

The water quality in South Africa's river systems is rapidly deteriorating as a consequence of increased discharge of wastewater effluents. The natural ability of rivers and reservoirs to trap toxic chemicals and nutrients in their sediments enables these systems to accumulate contaminants, altering the natural balance in environmental water quality, thereby raising a plethora of public and environmental health concerns. Impaired water quality has been linked to an array of problems in South Africa including massive fish mortalities, altered habitat template leading to the thinning of riverine macroinvertebrate diversity, shifts in microbial community structures with drastic ecological consequences and evolvement of antibiotic resistance genes that, under natural conditions, can be transferred to waterborne pathogens. Urban wastewater discharge has also been implicated in increased bioaccumulation of metals in edible plant parts, elevated concentrations of endocrine-disrupting compounds (EDCs), which are blamed for reduced fertility and increased cancer risk, excessive growth of toxic cyanobacteria and an increase in concentrations of pathogenic microorganisms which constitute a potential health threat to humans. However, despite the ecotoxicological hazards posed by wastewater effluents, ecotoxicological studies are currently underutilised in South African aquatic ecosystem assessments, and where they have been done, the observation is that ecotoxicological studies are mostly experimental and restricted to small study areas. More research is still needed to fully assess especially the ecotoxicological consequences of surface water pollution by urban wastewater effluents in South Africa. A review of the effects of urban effluent discharges that include domestic effluent mixed with industrial effluent and/or urban stormwater runoff is hereby presented.
