“…Scope for growth showed the pattern similar to that of clearance rate; therefore measuring SFG is occasionally simplified to measuring clearance (Ostroumov & Widdows, 2006;Donkin et al, 1989;Donkin et al, 1997). However, the determination of clearance rate as a single physiological parameter does not have the same power of discrimination as the more complete and integrated measure termed SFG.…”

This experiment was conducted to assess the effects of pollution on both the physiological and energetic characteristics (SFG) of Pteria aegyptiaca in the Gulf of Aqaba, Jordan. Four locations were chosen to represent both contaminated and uncontaminated locations. Phosphate Loading Berth (P) and the Industrial Area (I), represent contaminated locations, whilst the Hotels Area (H) and Marine Science Station (M) represent uncontaminated locations. The results of this experiment showed that contaminated regions had significant effects (P < 0.05) on respiration rate, clearance rate and absorption efficiency. A significant difference (P < 0.05) was identified between the scopes for growth of animals transplanted in contaminated regions compared with animals from uncontaminated locations. The Phosphate Loading Berth (P) and Industrial Area (I), showed the lowest SFG (18.7 ± 4.591 and 35.94 ± 7.412 Jh -1 respectively), reduced to only a half of SFG compared to uncontaminated locations. Results from our study indicate that oysters exposed to contaminated regions are highly compromised in both their energetics and physiology. Failure to improve the environmental conditions in these regions may have catastrophic effects on the micro and macro fauna.

“…Recovery of mussels following longterm exposure to low concentrations of diesel oil coincided with depuration of aromatic hydrocarbons (Widdows et al 1987). Donkin et al (1990) suggested that reductions in scope for growth in M. edulis were related to the accumulation of 2-and 3-ring aromatic hydrocarbons, as these compounds induced a narcotizing effect on ciliary feeding mechanisms.…”

“…Reductions in physiological measurements (e.g., respiration rates, carbon turnover, and scope for growth) have correlated with reduced growth rates measured for bivalve populations from oil-contaminated habitats (Gilfillan et al 1976;Gilfillan and Vandermeulen 1978). Alterations in bioenergetics and growth of bivalve molluscs appear to be related to tissue burdens of aromatic hydrocarbons (Gilfillan et al 1977;Widdows et al 1982Widdows et al , 1987Donkin et al 1990). Widdows et al (1982) demonstrated a negative correlation between cellular and physiological stress indices (lysosomal properties and scope for growth) and tissue concentrations of aromatic hydrocarbons with long-term exposure of M. edulis to low concentrations of North Sea crude oil.…”

“…Responses of M. edulis collected along a contaminant gradient in Langesundsfjord, Norway, showed alterations in lipid distribution, reductions in scope for growth, and increased occurrence of histopathological responses coincident with accumulation of PAHs and PCBs (Moore 1988;Capuzzo and Leavitt 1988;Widdows and Johnson 1988;Lowe 1988). Widdows et al (1990) examined changes in scope for growth in the turkey wing mussel (Arca zebra) collected along contaminant gradients in the waters surrounding Bermuda. Reduction in scope for growth as a result of both reductions in feeding rates and increases in metabolic expenditures correlated with significant accumulation of lead, tri-and di-butyltin, petroleum hydrocarbons and their polar oxygenated derivatives, and PCBs.…”

Marine bivalve molluscs such as the blue mussel (Mytilus edulis) and the soft shell clam (Mya arenaria) have been used as sentinel organisms of contaminant bioavailability and the biological consequences of contaminant exposure. Biological responses that may contribute to the impairment of reproductive and developmental processes include responses that can be categorized as interfering with bioenergetic processes such as feeding and nutrient allocation; biosynthetic processes, such as the synthesis of energy stores; and morphogenic processes, such as those involved in structural development. Case studies within New Bedford and Boston Harbors (Massachusetts) are used to examine the relationship between contaminant uptake and effects on the reproductive cycle and bioenergetics of mussels and soft shell clams. The results observed illustrate that disruption in bioenergetics in bivalve molluscs exposed to chemical contaminants can result in loss of reproductive output and increased susceptibility to disease. Differences in the extent of reproductive impairment may be linked specifically to energetic strategies of individual species.Natural and managed ecosystems are exposed continually to natural and anthropogenic perturbations. Physical destruction of habitats, input of toxic chemicals, and nutrient enrichment leading to eutrophication are among the stressors that result in alterations in the sustainability of coastal ecosystems and a reduction in biodiversity and harvestable yields. Ecological consequences of such stressors in coastal marine ecosystems include changes in parasitic infections (Lafferty and Kuris 1999; Lenihan et al. 1999), species distributions and abundance, degradation of habitats, and changes in energy flow and biogeochemical cycles. Inputs of toxic chemical contaminants can lead to impairment of feeding, growth, development, and recruitment of fish and shellfish populations that may result in alterations in reproductive and developmental success and changes in population structure and dynamics (Capuzzo 1987). Although contaminant exposure is often viewed as a single stressor, it is only one of many stressors that all populations of marine animals experience during their life cycles. The interactive effects of contaminant exposure and natural stressors, however, are not well understood, making it difficult to establish the relationship between responses of organisms to contaminated habitats and large-scale alterations in the functioning of marine ecosystems as well as large-scale contamination of fish and shellfish resources.Although general trends in the distribution of lipophilic organic contaminants in coastal ecosystems have been defined (e.g., NOAA 1989defined (e.g., NOAA , 1991, critical information on the biological effects of contaminants, specifically on population processes, is lacking. Recent studies of the incidence of tu-

“…The fact that the tissue residues were measured in tissues of free-ranging natural populations of marine animals indicates that the concentrations observed are not acutely lethal or debilitating to the marine animals. However, sublethal concentrations of the chemicals in tissues could lead to chronic sublethal effects on growth and reproduction, and thereby pose a risk to the long-term survival and success of the local populations (Donkin et al, 1989(Donkin et al, , 1991Widdows et al, 1995).…”
