“…Stress factors influence the composition of membrane lipids and, hence, the physical properties of the membrane, mainly microviscosity, so as to support its optimal structure (Nechev et al 2006). Changes in some lipids indices under the effect of pollutants have been demonstrated for blue mussels (Capuzzo and Leavitt 1988;Leavitt et al 1990), but these studies were made with whole animals. Yet, the response of a whole organism to different pollutants is integral, representing a sum of responses of different organs.…”

Bivalves have a known ability to accumulate different contaminants from ambient water and can therefore serve as bioindicators. The paper analyses certain biochemical and physiological parameters of blue mussels in response to varying oil product concentrations. The heart rate (HR) of blue mussels from the sublittoral zone exposed to different levels of oil products was investigated in a long-term experiment using non-invasive monitoring. A sharp rise in HR was observed at oil concentrations of 8.0 and 38.0 mg/l. A decreasing in mussel HR under the effect of lower concentrations (0.4 and 1.9 mg/l) was significant on the fourth day. Strong fluctuations of the cardiac activity were noted under all concentrations. After 6 days of oil treatment, tissues of the mussels were sampled to determine the total lipid composition. Low concentrations of oil products produced no reliable changes in the lipid composition whereas high concentrations induced significant changes in the ratio of lipid components (cholesterol and phospholipids).

“…Glycogen is a primary energy reserve in adult bivalves (De Zwaan and Zandee 1972;Gabbott 1983;Hummel et al 1989;Leavitt et al 1990) and is considered an appropriate indicator of condition for this group (Naimo and Monroe 1999;Patterson et al 1999;Gatenby 2000;Boyles 2004;Liberty 2004). Environmental changes can stress bivalves, evident by reduction in glycogen content (Hummel et al 1989;Naimo and Monroe 1999).…”

Pink heelsplitter mussels Potamilus alatus were held at two bottom locations and suspended in pocket nets in a pond at the Freshwater Mollusk Conservation Center, Virginia Polytechnic Institute and State University, for 1 year to evaluate survival in captivity. Survival after 1 year differed significantly; the poorest survival (30.0%) was at the bottom of the deep end (2.5 m), and there was no difference in survival) at the shallow end (83.3%; 0.6 m) and in pocket nets (63.3%; 1-1.5 m). Monthly survival was inversely related to water temperature (R ¼ À0.72); the lowest monthly survival occurred in summer, resulting in a significant difference among the three locations. Differences in the mean glycogen content of mussels among the three containment locations and wild-sampled pink heelsplitter mussels were significant (P ¼ 0.001); the highest value was in mussels at the shallow end and the lowest value was in mussels at the deep end. We used pocket nets to hold surgically implanted mussels and measured glycogen reserves to monitor body condition and assess the potential of the pink heelsplitter mussel to produce nonnucleated and image pearls. Results of the pearl culture experiment in two ponds showed that nonnucleated pearls and image pearls with purple or purplish luster were successfully produced. There was no significant difference in pearl weight in mussels held in the two experimental ponds under different environmental conditions. Similarly, no differences in monthly survival rates of mussels were observed in either pond or among mussels with surgical implants and the no-surgery control mussels. Therefore, pink heelsplitter mussels can be considered a potentially suitable species for producing purple pearls in farm pond environments.
