Population Dynamics of the Freshwater Clam Galatea Paradoxa from the Volta River, Ghana
Knowledge and Management of Aquatic Ecosystems (2012) 405, 09 http://www.kmae-journal.org c ONEMA, 2012 DOI: 10.1051/kmae/2012017 Population dynamics of the freshwater clam Galatea paradoxa from the Volta River, Ghana D. Adjei-Boateng(1),,J.G.Wilson(2) Received February 6, 2012 Revised April 25, 2012 Accepted May 7, 2012 ABSTRACT Key-words: Population parameters such as asymptotic (L∞), growth coefficient (K), recruitment, mortality rates (Z, F and M), exploitation level (E) and recruitment pattern mortality, of the freshwater clam Galatea paradoxa were estimated using length- growth frequency data from the Volta River estuary, Ghana. The L∞ for G. para- parameters, doxa at the Volta estuary was 105.7 mm, the growth coefficient (K)and Volta River, the growth performance index (Ø)´ ranged between 0.14–0.18 year−1 and Bivalvia 3.108–3.192, respectively. Total mortality (Z) was 0.65–0.82 year−1, while natural mortality (M) and fishing mortality (F) were 0.35–0.44 year−1 and 0.21–0.47 year−1, respectively, with an exploitation level of 0.32–0.57. The recruitment pattern suggested that G. paradoxa has year-round recruit- ment with a single pulse over an extended period (October–March) in the Volta River. The Volta River stock of G. paradoxa is overfished and requires immediate action to conserve it. This can be achieved by implementing a minimum landing size restriction and intensifying the culture of smaller clams which is a traditional activity at the estuary.

Molluscs: Bivalvia Laura A
I Molluscs: Bivalvia Laura A. Brink The bivalves (also known as lamellibranchs or pelecypods) include such groups as the clams, mussels, scallops, and oysters. The class Bivalvia is one of the largest groups of invertebrates on the Pacific Northwest coast, with well over 150 species encompassing nine orders and 42 families (Table 1).Despite the fact that this class of mollusc is well represented in the Pacific Northwest, the larvae of only a few species have been identified and described in the scientific literature. The larvae of only 15 of the more common bivalves are described in this chapter. Six of these are introductions from the East Coast. There has been quite a bit of work aimed at rearing West Coast bivalve larvae in the lab, but this has lead to few larval descriptions. Reproduction and Development Most marine bivalves, like many marine invertebrates, are broadcast spawners (e.g., Crassostrea gigas, Macoma balthica, and Mya arenaria,); the males expel sperm into the seawater while females expel their eggs (Fig. 1).Fertilization of an egg by a sperm occurs within the water column. In some species, fertilization occurs within the female, with the zygotes then text continues on page 134 Fig. I.

Abstract: The factors involved in promoting long life are extremely intriguing from a human perspective. In part by confronting our own mortality, we have a desire to understand why some organisms live for centuries and others only a matter of days or weeks. What are the factors involved in promoting long life? Not only are questions of lifespan significant from a human perspective, but they are also important from a paleontological one. Most studies of evolution in the fossil record examine changes in the size and the shape of organisms through time. Size and shape are in part a function of life history parameters like lifespan and growth rate, but so far little work has been done on either in the fossil record. The shells of bivavled mollusks may provide an avenue to do just that. Bivalves, much like trees, record their size at each year of life in their shells. In other words, bivalve shells record not only lifespan, but also growth rate. -

ANNOTATED CHECKLIST OF MOLLUSKS OF CHESAPEAKE BAY (Revised April 1956) J. D. Andrews Virginia Fisheries Laboratory Gloucester Point This preliminary checklist has been prepared for the use of students and biologists working in the Chesapeake Bay area. The list is conservative and probably omits a number of species, especially small snails and parasitic groups like the pyrams. All species listed, with one or two exceptions, have been collected as live specimens by the author, and collections of each have been deposited in the U. S. National Museum. Species given in the literature but not yet confirmed by specimens in the National Museum have been purposely omitted. The checklist includes all species collected in the brackish waters of Chesapeake Bay except certain fresh-water groups, e.g. the hydrobiids, which invade salty waters a short distance. The ocean shore of Virginia, both on Eastern Shore and the mainland, has been excluded. The families are arranged in the order found in Johnson's checklist and the nomenclature follows Johnson except where Abbott or Johnsonia give changes. -
