“…from Pindo showed significantly less growth than the other populations (Miranda and Redes). Slow growth has also been reported in other studies when different species of bivalves have been exposed to pollutants (Strömgren, 1982;Strömgren and Bongard, 1987;Salazar and Salazar, 1991;Guolan and Yong, 1995;Soto et al, 2000), specifically hydrocarbons (Strömgren et al, 1986;Le Floch et al, 2003). Growth in weight was significantly less in the Pindo mussels than in the other populations, so because growth in weight has been reported as more sensitive than growth in length as a response to environmental change Salazar, 1991, 1995), this is the likely reason for the differences in growth rates measured here.…”

“…Both natural stress and that related to pollution have been linked to reduced growth rates in terms of both shell length and weight, although both these growth metrics may be influenced by different factors (Salazar and Salazar, 1995;Dame, 1996). Such patterns have been reported in several studies in which growth rates declined as a consequence of exposure of mussels to chemicals such as hydrocarbons, TBT, or heavy metals (Strömgren, 1982;Strömgren et al, 1986;Strömgren and Bongard, 1987;Salazar and Salazar, 1991;Guolan and Yong, 1995;Soto et al, 2000;Le Floch et al, 2003).…”

Growth of mussel Mytilus galloprovincialis using raft culture was investigated for the first cultured generation following the Prestige oil spill off northwestern Spain. Seed from three natural populations along the Galician coastline, Pindo, Miranda, and Redes, was transplanted to a raft culture system in Ría de Ares-Betanzos. The physiological and biochemical status of mussels at the onset of culture and the degree of oil exposure three months after the spill (February 2003) have been described already, but here growth patterns of three populations sampled monthly from seeding to thinning-out (March/August 2003) and from thinning-out to harvest (August 2003/February 2004) were assessed. Mussels from Pindo (the area most affected by the oil spill) showed significantly less growth by weight than the other populations, resulting in a lower yield at harvest. The percentage of mussels classified as “large” in the Pindo population at harvest was also significantly less than that of the other two mussel populations.

“…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.

“…The vehicle control, 20 mL of corn oil, was also microencapsulated as described above. This procedure reportedly gives microcapsules with a diameter of 1-10 µm, with most of the capsules around 5 µm, and stable with respect to particle dispersion and size (Stromgren et al, 1986). …”

The relationship between hemic neoplasia, a blood cell disorder in bivalve molluscs, and chemical contaminants was evaluated in the common mussel (Mytilus edulis complex). Hemic neoplasia (HN) is endemic to mussel populations in Puget Sound. The prevalence of hemic neoplasia ranged from 0 to 30% in mussels from nine sites in Puget Sound, Washington. Organic chemical contamination in sediment from these sites range from 0.1 to 64.0 ppm of polycyclic aromatic hydrocarbons (PAHs) and 0.07 to 0.50 ppm chlorinated hydrocarbons. No relationship between the body burden of environmental contaminants and the prevalence of HN in mussels was identified. To evaluate the shortterm ability of chemical contaminants to induce HN in mussels, mussels, from a site where mussels were previously determined to be HN free, were fed microencapsulated PAHs (composed of a mixture of phenanthrene, flouranthene, and benzo[a]pyrene) or PCBs (Aroclor 1254) and the prevalence of HN was assessed after 30 days of exposure. Although an apparent increase in HN prevalence (20 to 30%) was observed in all treatments groups except the untreated controls, no significant difference in the prevalence of HN was observed between the control group of mussels fed corn oil (vehicle) and mussels fed either PAHs or PCBs in corn oil. A long-term (180-day) exposure study was conducted to evaluate the influence of PAHs or PCBs in modulating the prevalence of HN in a mussel population already exhibiting a moderate HN prevalence. Mussels, from a site where mussels were previously determined to exhibit a background prevalence of HN, fed microencapsulated PAHs, PCBs, and corn oil (vehicle) over a long time period (180 days), revealed an apparent increased prevalence of HN (30 to 40%) above the low levels (20%) initially present. However, no significant difference in the prevalence of HN was observed between the control group of mussels fed corn oil (vehicle) and mussels fed either PAHs or PCBs in corn oil. Although chemical contaminants have been proposed as a modulating factor in the development and promotion of HN in bivalve molluscs from environmentally stressed and degraded habitats, we find no evidence that chemical contaminants induce or promote the development of HN in the mussel M. edulis complex.
