Morphological Variations of the Shell of the Bivalve Lucina Pectinata
I S S N 2 3 47-6 8 9 3 Volume 10 Number2 Journal of Advances in Biology Morphological variations of the shell of the bivalve Lucina pectinata (Gmelin, 1791) Emma MODESTIN PhD of Biogeography, zoology and Ecology University of the French Antilles, UMR AREA DEV ABSTRACT In Martinique, the species Lucina pectinata (Gmelin, 1791) is called "mud clam, white clam or mangrove clam" by bivalve fishermen depending on the harvesting environment. Indeed, the individuals collected have differences as regards the shape and colour of the shell. The hypothesis is that the shape of the shell of L. pectinata (P. pectinatus) shows significant variations from one population to another. This paper intends to verify this hypothesis by means of a simple morphometric study. The comparison of the shape of the shell of individuals from different populations was done based on samples taken at four different sites. The standard measurements (length (L), width or thickness (E - épaisseur) and height (H)) were taken and the morphometric indices (L/H; L/E; E/H) were established. These indices of shape differ significantly among the various populations. This intraspecific polymorphism of the shape of the shell of P. pectinatus could be related to the nature of the sediment (granulometry, density, hardness) and/or the predation. The shells are significantly more elongated in a loose muddy sediment than in a hard muddy sediment or one rich in clay. They are significantly more convex in brackish environments and this is probably due to the presence of more specialised predators or of more muddy sediments. Keywords Lucina pectinata, bivalve, polymorphism of shape of shell, ecology, mangrove swamp, French Antilles. -

FISHER* AND DAVID B. RUDDERS Virginia Institute of Marine Science, College of William and Mary, PO Box 1346, Gloucester Point, VA 23062 ABSTRACT Channeled whelks, Busycotypus canaliculatus, support commercial fisheries throughout their range along the US Atlantic seaboard. Given the modest amounts of published information available on channeled whelk, this study focuses on understanding the temporal and spatial variations in growth and reproductive biology in the Mid-Atlantic region. Channeled whelks were sampled from three inshore commercially harvested resource areas in the US Mid-Atlantic: Ocean City, MD (OC); Eastern Shore of Virginia (ES); and Virginia Beach, VA (VB). The largest whelk measured 230-mm shell length (SL) and was recorded from OC. -
