“…All other bivalves are infaunal, either living buried in the sediments or living at the mud-water interface partially buried in the sediments . Musculium transversum (Gale, 1969)), but most occur in a variety of substrate types, the particle sizes ranging from mud to coarse gravel . Typically, only the posterior third to half of the unionid shell projects above the surface of the substrate while it is siphoning for respiratory and feeding purposes .…”

The zebra mussel, Dreissena polymorpha, is a new exotic species that was introduced into the Great Lakes as early as the fall of 1985 . It differs markedly from native species of bivalves in its : (i) shell form ;(ii) mode of life ; (iii) reproductive potential ; (iv) larval life cycle ; (v) population dynamics ; (vi) distribution, (vii) dispersal mechanisms ; (viii) physiology ; (ix) potential impact on the ecosystem ; and (x) impact on society and the economy . In body form, it has an anterior umbone, a flat ventral surface with permanent aperature for the byssal apparatus and a shape that together make the animal well adapted for life on a hard surface . The shell has a zebra-stripe pattern, a heteromyarian muscle condition and lacks hinge teeth which make it easily identifiable from native bivalves . The zebra mussel is strongly byssate and has an epifaunal mode of life not seen in native bivalves . The species is dioecious and has external fertilization, the eggs developing into pelagic veligers which remains planktonic for approximately 4 weeks . Gametogenesis begins in late winter to early spring, veligers appear in the water column in late May to early June and disappear in mid to late October in Lake St . Clair . Adults live for about 2 years and have very rapid growth rates . Maximum shell lengths average 2 .3 to 2 .5 cm . Standing crops as high as 200 000 m-2 are present in the 1-m depths of the Ontario shores . Infestations may be interfering with the normal metabolism of native unionid clams and there is potential of the unionid clam populations being reduced or even eliminated from Lake St . Clair .

“…From the above, it is clear that life history characters of the Pisidiidae are potentially highly variable, making inter-population comparisons difficult to interpret, but also raising the probability that the reproductive strategies of many other species might be more variable than is at present appreciated. However, Table I Gale, 1969Mitropolskji, 1965Way et al, 1980Mackie, 19786, 1979Mackie & Huggins, 1983 This study intra-specific variability, as discussed above.

“…Pisidiids are hermaphroditic, ovoviviparous (Mackie, 1978a) and typically semelparous, e.g. Sphaerium striatinum (Avolizi, 1976;Hornbach & Wissing, 1982) and the majority are species of Musculium (Mitropolskji, 1965;Gale, 1969;Mackie, 19786, 1979;Mackie & Huggins, 1983). Other species of Sphaerium, e.g.…”

The population dynamics, reproductive strategy and life history tactics of Musculium lacusfre (Bivalvia: Pisidiidae) in Hong Kong

With 1 plate and 9 figures in the text)Hitherto uninvestigated in Hong Kong are the population dynamics, reproductive strategies and life history tactics of the Pisidiidae of which three species are known to occur locally. This study is of Musculium lacustre inhabiting a drainage ditch of the Lam Tsuen River in the New Territories of Hong Kong and extended over 15 months during 1983-84.In Hong Kong, M. lacustre is a protandric, simultaneous hermaphrodite that matures at a length of 2 mm; the majority of each generation is, however, not mature until a length of between 4-6 mm is attained. Fertilized eggs are brooded in the inner demibranchs until they reach a length of 1.5 mm when they are released as post-foetal larvae. Musculium lacustre is univoltine. Reproduction occurs twice a year but, since M . lacustve is semelparous, the population contains, at any one time, two overstepping generations. Thus, a spring generation is recruited and grows rapidly to generate a second, smaller, autumn generation. This in turn grows rapidly and matures to produce the spring generation of the succeeding year. Adult mortality occurs in late summer and winter. A few of the late-born spring generation may overwinter to contribute to the spring generation of the succeeding year. This is not so with the autumn generation.Such sexual and life history tactics can be related to the climate and hydrology of Hong Kong and its freshwater habitats. Reproduction takes place in spring and autumn when temperatures are moderate. Mortality is high in summer and winter when the habitat is either, respectively, hot and flushed out by summer rains or cold and dry. As M . larustre is able to overwinter but not aestivate at these latitudes (22' N), it is postulated that this holarctic species is approaching the southern limit of its asiatic range. Musculium larustre is compared with the other bivalves inhabiting fresh and brackish-water habitats in southern China.

In substrate preference experiments, the fingernail clam, Sphaerium transverum, preferred mud (about 90% clay and slit). Sandy mud and sand ranked second and third, respectively. Clam movement during experimentation appeared random, with no detected differences due to current or innate dispersal tendencies. Experiments were conducted by using a circular substrate apparatus and a novel application of Latin—square statistical design.
