“…In addition, expousure of Tilapia mossambica to organophosphate insecticides resulted in the inhibition of oxydative enzymes such as succinate dehydrogenase, lactate dehydrogenase, malate deydrogenase, and cytochrome c oxidase in gill, brain, and striated muscle tissues (Rao and Rao, 1979; Basha et al, 1984). However, Rao and Rao (1979) also found total protein and free amino acids levels to significantly increase in muscle and gill of fish exposed to sublethal concentrations of methyl parathion.…”

“…In fish, this toxicant has been shown to inhibit oxygen consumption and oxidative enzymes (Rao and Rao, 1979;Vijayalakshmi, 1980;Basha et al, 1984). For example, the maximum temperature at which the whole organism can survive is usually lower than the maximum temperature at which many of its constituent tissues and cells can function (Ushakov, 1964;Roberts, 1973;Lagerspetz, 1987).…”

“…Therefore, elicitation of the SPR by either of these chemicals, most likely, would not be able to be explained by classical SPR and mode of action definitions but through other mechanisms, such as disruption of the membrane lipidic matrix (Demael et al, 1987) or inhibition of oxidative processes (Rao and Rao, 1979; Vijayalakshmi, 1980;Basha et al, 1984).…”

To evaluate the potential use of the SPR as a biomonitoring tool, a stepwise plan was utilized that proceeded through various physical and chemical laboratory exposures and culminated with a field validation study. The goals of the laboratory exposures were threefold: 1) determine the time required for induction of the SPR; 2) determine the dose-responsiveness of the SPR; and 3) compare the increased syntheses and accumulations of stress proteins to classical toxicological endpoints (i.e. percent mortality, LC50, LC1, etc).Brain, gill, and striated muscle tissues of fathead minnows (Pimephales promelas) exposed to heat shock, sodium arsenite, sodium chromate, lindane, and diazinon elicited tissue and stressor specific translation patterns. Increased syntheses and accumulations of several proteins were found to be concentration dependent at environmentally relevant levels. All tissues under all exposure regimes elicited a 70 kD protein. This protein was determined to be indicative of general stress. Two proteins of 20 and 30 kD were only found in fish exposed to arsenite and chromate. Thus, these two proteins may serve as metal indicators.Gill of fathead minnows exposed in situ to a toxicity gradient in Soldier Creek, Midwest City, Oklahoma were found to accumulate stress protein 70 in a manner that reflected in stream fish species richness.The results of this research demonstrates that the stress protein response has potential as a rapid and environmentally relevant biomonitoring method for assessing both general and stressor specific perturbations in fish. Figure 3. A. A fluorogram of striated muscle protein from fathead minnows exposed to 34 0 C for 1-hour and then transferred to 25 0 C for 11 hours and sampled at 0, 1, 3, 7, and 11 hours post heat shock exposure. Molecular weight markers of 97, 66, 42, 31, 21, and 14 kD, respectively, are designated on the left. Arrows on the right denote heat shock proteins of 90, 78 and 70 kD. B. Median intensities of 90, 78, and 70 kD proteins in fluorograms from replicate samples (n = 3) of experiment described in A. Intensities were determined densito metrically and are presented as arbitrary units (see Materials and methods Unfortunately, their clinical use is lacking (Bouk, 1984). Clinical use implies that the method has been validated by extensive testing-both to identify the biological significance of the parameter and the limitations in applying the test to the species in question.Much of the early biomarker work involved measurements of blood and enzyme activity as well as biochemical composition of blood and tissues (Mazeud and Mazeud, 1981;Neff, 1985), methods primarily transplanted from human and veterinary medicine. Unfortunately, many of these parameters were not applicable across phyla and measured secondary effects, symptoms, of an underlying problem rather than highly conserved parameters intimately involved in the protection and/or defense of the cell. Thus, biomarkers that correspond to events that are coupled to cellular protection and defens...

“…An important physiological parameter to assess toxic stress of an animal is the respiration rate, because it is a valuable indicator of energy expenditure in particular and metabolism in general (e.g. Basha et al 1984). Toxicant exposure can either increase and/or decrease oxygen uptake of aquatic animals (Widdows & Donkin 1991, Widdows & Page 1993.…”

The successful persistence of Capjtella spp. in disturbed and/or oil-polluted habitats is widely known, but demographic adaptations might be only part of the explanation and little is known about differences among species. The present study investigates ecophysiological effects of the common PAH (polycyclic aromatic hydrocarbon) fluoranthene (FLU) on juvenile and adult survival, comparing 3 sibling species of CapiteUa (Polychaeta; Capitellidae). Subsequently, the influence of FLU on the aerobic and anaerobic metabolism in the most 'sensitive' species, CapiteUa sp. S, and most 'tolerant' species, Capitella sp. I, was assessed. Oxygen uptake and internal succinate concentrahon (an indicator of anaerobic metabolism) were measured after short-term (7 h) and long-term (2 wk) FLU pre-exposure (100 pg g-'). FLU exposure reduced mean survival times of juveniles (4 d old) of all sibling species, but tolerance varied among the 3 species of Capitella adults. Capitella sp. S, originally collected from 'clean' oxygen-nch North Sea intertidal sedments, was most sensit~ve and CaplteUa sp. M, and Capitella sp. I, which is the most opportunistic of the sibling species described to date, were most tolerant. In Cap~tella sp. S, O2 uptake decreased at lower ambient oxygen levels and increasing FLU concentrations increased oxygen consumption. Similarly, O2 uptake decreased at lower ambient oxygen levels in Capitella sp-I; however, FLU concentrations had no effect on oxygen uptake. For both species, anaerobic metabolism increased with declining ambient oxygen levels, and was influenced by FLU exposure in CapiteUa sp.S, but not m Capjtella sp. I. Part of the explanation for the success of Capitella sp. I in oil-polluted habitats may be that this species is able to channel energy into vital processes without a measurable increase in energy expenditure. We conclude that these 3 CapiteUa species are ecophysiologically diverse in their responses to toxicant exposure. Our results suggest that toxicant tolerance differences among sibhng species have a genetic basis and that increased aerobic and anaerobic metabolic rates in response to toxicant exposure can have negative survival consequences. This has to be considered when using these species as pollution indicators or to improve sediment quality.
