“…Through filtering large quantities of water, mussels are exposed to lipophilic PAHs, which are known to bioconcentrate by 2-5 orders of magnitude within mussel tissue (Neff 2002). This exposure to hydrocarbons can decrease population (Peteiro et al, 2006) and individual growth rates (Stromgren et al, 1986;LeFloch et al, 2003), lower condition indices (Bayne and Worrall, 1980), and lower feeding rates (clearance rates) (Widdows et al, 1981;Widdows et al, 1987;Widdows et al, 1996)..…”

In September 1969, the Florida barge spilled 700,000 L of No. 2 fuel oil into the salt marsh sediments of Wild Harbor, MA. Today a substantial amount, approximately 100 kg, of moderately degraded petroleum remains within the sediment and along eroding creek banks. The ribbed mussels, Geukensia demissa, which inhabit the salt 2 marsh creek bank, are exposed to the spilled oil. Examination of short-term exposure was done with transplantation of G. demissa from a control site, Great Sippewissett marsh, into Wild Harbor. We examined the effects of long-term exposure with transplantation of mussels from Wild Harbor into Great Sippewissett. Both the short-and long-term exposure transplants exhibited slower growth rates, shorter mean shell lengths, lower condition indices, and decreased filtration rates. Our results add new knowledge about long-term consequences of spilled oil, a dimension that should be included when assessing oil-impacted areas and developing management plans designed to restore, rehabilitate, or replace impacted areas. Capsule Ribbed mussels exposed to residual petroleum in salt marsh sediments, in short-term and long-term transplant experiments, exhibited significant effects that should be considered when assessing oil-impacted areas and developing management plans.

“…Sampling surveys were carried out seasonally at two sites subjected to different fishing efforts: a free fishing area at S. Angelo (central basin) and an area licensed for clam farming at Chioggia (southern basin), where a control sub-area was established. Two SFG values were also evaluated: one was calculated with POM and AE values, in order to highlight environmental differences between S. Angelo and Chioggia, and the other with standardized POM (0.4 mg) and AE (0.45) values, to better reveal the effects of stress due to fishing, when other natural potential stressors were held constant (Widdows et al, 1997).…”

“…These results suggest that R. philippinarum is highly tolerant to environmental changes. It should also be noted that, as observed by Widdows et al (1997) in Mytilus galloprovincialis, food supply in the Lagoon of Venice is so abundant everywhere throughout the year that it counteracts the detrimental effects of both natural and anthropogenic stressors on clam physiological responses. Nevertheless, when the SFG calculated by standardized POM and AE values was considered, in July negative SFG values were observed, highlighting the negative effect of high water temperature on physiological rates, as already observed in other clam species such as R. decussatus and Chamelea gallina (Sobral and Widdows, 1997a,b;Moschino and Marin, 2006).…”

“…Among these, clearance and respiration rate, scope for growth and the survival-in-air test are known to be responsive to previously experienced stress conditions, mostly related to pollution (Eertman et al, 1993;Widdows et al, 1997;Wepener et al, 2008), and to be useful for comparing various bivalve populations (Labarta et al, 1997;Marin et al, 2001). Scope for growth (SFG) estimates the amount of energy available for growth and reproduction by measuring the organism's energy budget, and is defined as the difference between energy absorbed from food and energy lost via excretion and metabolism (Smaal and Widdows, 1994).…”

SUMMARY: The Manila clam (Ruditapes philippinarum)is an important economic resource for fisheries in the Lagoon of Venice, where this species is fished and farmed. With the aim of evaluating possible fishing-induced long-term effects undergone by clam populations subjected to fishing efforts, physiological biomarkers were measured at organism level (clearance and respiration rates, scope for growth and survival-in-air test). Clams were collected on a seasonal basis from sites characterized by various fishing management practices: a free fishing area at S. Angelo and an area licensed for clam farming at Chioggia, where a non-fishing sub-area was established. R. philippinarum collected at S. Angelo generally showed reduced filtering activity and higher oxygen consumption, revealing general worsening in clam well-being in comparison with individuals from both Chioggia areas. This condition, resulting in lower standardized scope for growth values, may be explained by both environmental and fishing effort differences. Comparing Chioggia samples, better physiological performances were exhibited by clams from the non-fishing area, though no significant differences were observed. In winter, the survival-in-air test revealed the detrimental effects of fishing on clams, whereas in the other seasons this response generally seemed to be mostly related to other exogenous and endogenous factors. Although differences among sites and seasons were always statistically significant, all physiological parameters indicate the great tolerance of R. philippinarum to changing environmental conditions. Keywords: Ruditapes philippinarum, Lagoon of Venice, physiological responses, scope for growth, fishing impact, clam culture.RESUMEN: Efectos a largo plazo de la pesca en el rendimiento fisiológico de la almeja de Manila Ruditapes philippinaRum en la laguna de Venecia. -La almeja Ruditapes philippinarum representa un recurso económico importante para la pesca en la laguna de Venecia, donde esta especie se pesca y se cría. Para evaluar los posibles efectos a largo plazo sufridos por las poblaciones de almejas expuestas al esfuerzo de pesca, se han medido algunos marcadores fisiológicos a nivel de los organismos (tasa de aclarado, tasa de respiración, energía disponible para el crecimiento y supervivencia en pruebas fuera del agua). Las almejas se recolectaron estacionalmente en lugares caracterizados por varias prácticas de gestión de la pesca: un área de pesca libre en S.Angelo y un área autorizada para la crianza de almejas en Chioggia, donde se puso una sub-área no usada para la pesca. R. philippinarum recogida en S. Angelo generalmente ha mostrado una actividad de filtración reducida y una consumición de oxígeno más alta, entonces hubo un empeoramiento en el bienestar de las almejas en comparación con los individuos de ambas área de Chioggia. Esta condición, que resulta en valores más bajos en la energía disponible para el crecimiento estandarizada, puede ser explicado por las diferencias ambientales y de la pesca.
