“…Complex biochemical and physiological mechanisms enable this organism to survive under these extreme conditions and to recover from hypoxia resulting from exposure at low tide (de Zwaan and Wijsman, 1976;Shick et al, 1986;Zange et al, 1989). On the other hand, behavioral mechanisms, such as shell gapping, may also enhance survival at low tides, where small shell movements can assist both in the maintenance of aerobic metabolism (Kennedy, 1976;Widdows et al, 1979;Guderley et al, 1994) and the removal of anaerobic waste products . One strategy commonly used by intertidal bivalves during tidal exposure is a reduction in oxygen consumption.…”

“…One strategy commonly used by intertidal bivalves during tidal exposure is a reduction in oxygen consumption. Some bivalves, including Mytilus edulis, Mytilus galloprovincialis (Widdows et al, 1979), Choromytilus meridionalis (Griffiths and Buffestein, 1981) and Perna canaliculus (Marsden and Weatherhead, 1998) show reductions of up to 80% in their oxygen uptake under these conditions. Willson and Burnett (2000) observed that the oxygen uptake of the oyster Crassostrea virginica exposed to air was less than 0.1% of their oxygen uptake in well-aerated seawater.…”

Investigations were carried out to evaluate the antioxidant defenses in digestive gland of mussels Perna perna held in air for 4 hours, exposed to air for 4 hours followed by submersion in water for 30 minutes, and constantly submerged for 4.5 hours. No differences were observed in CAT and GPx activities and in the levels of total GSH. Mussels exposed to air had significantly higher SOD activity, possibly related to a preparative mechanism of defense against oxidative stress during reoxygenation.

“…However, Seed (1969b) reported that some mussels in the mid intertidal zone in Yorkshire, England, grow to 30 mm SL in -10 yr, although the majority of the mussels are more slow growing. More rapid growth on emergent substrata may be related to a reduced metabolic rate during exposure to air (Widdows et al 1979, Clarke & Griffiths 1990). …”

The distribution, size structure, and dynamics of mussel (A4ytllus trossulus, Ad edulis) patches in tidepools were studied on an exposed rocky shore near Halifax. Nova Scotia, Canada. The mussel patches were dynamic, frequently coalescing with one another or disappearing, but mean change in patch area did not vary significantly among seasons or years. Recolonization of areas from which patches were removed occurred slowly, usually by recruitment. Both established and recolonized patches were generally associated with macroalgae. Mussel patches were primarily composed of individuals < S mm in shell length (SL) which appeared to be very slow growing. The percentage of new recruits in a patch varied among pools and between years. Predation by the dogwhelk Nucella lapillus was a major cause of mussel mortality. The size distributions of live and dead mussels in the patches differed significantly: the frequency of dead mussels <5 mm SL was less than that of live mussels, and the frequency of dead mussels 5 to 10 mm SL was greater than that of live mussels. Dead mussels (not lulled by whelks) were more frequent in October 1992 than in June 1992, while no clear temporal patterns were found in the frequency of mussels killed by whelks.

“…In the latter condition normally aerobic activities as filtration may continue. On the other hand some oxygen consumption in air as observed by Widdows et aL (1979) could influence the extent to which anaerobic end products are formed.…”

“…Recently it was demonstrated by Widdows et al (1979) that M. edulis is able to consume some oxygen from the air when exposed, but anaerobic end products still accumulate in the tissues. In our investigation two experimental conditions were compared: exposure to air and incubation in oxygen-free seawater to investigate to what extent the oxygen consumption in air influences formation of anaerobic end products.…”

1. Anaerobic energy metabolism was investigated in different organs of Mytilus edulis and the whole animal.2. Succinate accumulates to high levels in most organs but remains low in the hemolymph. 3. After 16 hours propionate accumulation is observed in all organs. Experimental evidence is not sufficient yet to point out organs that produce more propionate than others.4. Acetate is a minor end product. 5. Acetate and propionate are found in the hemolymph in amounts equal to those in the organs. 6. Animals incubated in oxygen-free seawater accumulate more end products than animals exposed to air, in the form of volatile fatty acids that are excreted into the incubation water.7. Alanine and glutamate increase in the posterior adductor muscle. Aspartate decreases in the total animal, posterior adductor muscle and gills, while in the hemolymph decreases in alanine, asparagine, serine, threonine and proline are observed.
