The relationship between growth rate, rate of morphological development, and length of larval life, was examined for larvae of the blue mussel Mvtilus edulir L. The larvae were reared at phytoplankton (Isochrysis galbana, clone T-ISO) concentrations between 0.5 x 10“ and 30 x 104 cells. ml’ at either 12 or 16 “C. Growth rates generally increased with increasing food concentration and were highe...

We used the combination of preparative electrophoresis and immunological detection to isolate two new proteins from the shell calcitic prisms of Pinna nobilis, the Mediterranean fan mussel. The amino acid composition of these proteins was determined. Both proteins are soluble, intracrystalline, and acidic. The 38-kDa protein is glycosylated; the 17-kDa one is not. Ala, Asx, Thr, and Pro represe...

. Abstract: Mussel culture is an expanding activity in shalIow and sheltered bays along the coast of Santa Catarina, southern Brazil. Although mussel culture generates benefits, several environmental impacts are associated with this kind of activity. Its success depends on. factors which include the environmental impact and the carrying capacity of the system. One conspicuous effect of mussel c...

As more ecological work is being conducted on freshwater mussels, we are coming to appreciate the importance of this secretive fauna to ecosystem function and structure. Yet we still lack an understanding of the factors that control the distributions of this group, their reproductive strategies, the fish hosts they use, and the factors causing their decline. This book provides a thorough litera...

Aiming to investigate the efficacy of different materials as bio-sorbents for the purification of As-polluted waters, batch-type experiments were employed to study As(V) sorption and desorption on oak ash, pine bark, hemp waste, mussel shell, pyritic material, and soil samples, as a function of the As(V) concentration added. Pyritic material and oak ash showed high sorption (90% and >87%) and l...

1. The ligament of Mytilus edulis is situated between the valves of the shell imme diately below the dorsal margin and may be divided into two main layers, the inner and the outer, the principal features of which appear to correspond with those of other bivalves. 2. The outer layer is subjected to a tensile strain transverse to the longitudinal plane of the shell, which is imposed by the additi...

The ecology and biogeography of meiofauna at deep-sea hydrothermal vents have historically received less attention than those of megaand macrofauna. This study examines the composition of major meiofaunal taxa in beds of the mussel Bathymodiolus thermophilus at hydrothermal vents on the northern and southern East Pacific Rise (EPR) and presents the first comparison of species assemblages of the...
