C. The occurrence of the thaidid gastropod genus Concholepas is recorded from presumed Late Pleistocene coastal deposits in southern South West Africa-Namibia. The material is indistinguishable from C. concholepas, a species known from the Pliocene to Recent on the west coast of South America. The living species characteristically occurs in cold-temperate waters from the intertidal to depths of 40 m. It is suggested that the southern African fossils represent a short-lived pioneer population, established by larvae drifting from South America. -

Genetic Structure and Diversity of Squids with Contrasting Life Histories in the Humboldt Current System Estructura Y Diversidad

Las Palmeras # 3425, Ñuñoa. Chile e-mail: [email protected] Ibáñez C. M and Elie Poulin. 204. Genetic structure and diversity of squids with contrasting life histories in the Humboldt Current System. Hidrobiológica 24 (): -0. ABSTRACT Dosidiscus gigas and Doryteuthis gahi are the most abundant squids in the Humboldt Current System (HCS). These species have contrasting life histories. To determine the genetic structure and diversity of these species, we collected samples from different places in the HCS and amplified a fragment of the mitochondrial cytochrome C oxidase I gene. The molecular analysis of D. gigas revealed low genetic diversity, absence of population structure and evidence for a demographic expansion during the transition from the last glacial period to the current interglacial. These results sug- gest that D. gigas is composed of one large population with high levels of gene flow throughout the HCS. In the case of D. gahi, the sequences indicated the presence of two population units in the HCS, one in south-central Chile and one in Peru. The Chilean unit had greater genetic diversity, suggesting that it is an old, relatively stable population. In the Peruvian unit there was less genetic diversity and evidence of a recent demographic expansion. -
Shelled Molluscs
Encyclopedia of Life Support Systems (EOLSS) Archimer http://www.ifremer.fr/docelec/ ©UNESCO-EOLSS Archive Institutionnelle de l’Ifremer Shelled Molluscs Berthou P.1, Poutiers J.M.2, Goulletquer P.1, Dao J.C.1 1 : Institut Français de Recherche pour l'Exploitation de la Mer, Plouzané, France 2 : Muséum National d’Histoire Naturelle, Paris, France Abstract: Shelled molluscs are comprised of bivalves and gastropods. They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric tons landed worldwide in 1996. Aquaculture, which mainly concerns bivalves (oysters, scallops, and mussels) relies on the simple techniques of producing juveniles, natural spat collection, and hatchery, and the fact that many species are planktivores.

MARINE ECOLOGY PROGRESS SERIES Published July 20 Mar Ecol Prog Ser 1 Effects of human activities on long-term trends in sandy beach populations: the wedge clam Donax hanleyanus in Uruguay Omar Defeo*, Anita de Alava Instituto Nacional de Pesca, Casilla de Correo 1612, 11200 Montevideo, Uruguay ABSTRACT: A long-term analysis of the structure of a bivalve population consisting of the wedge clam Donax hanleyanus is described for an exposed temperate sandy beach of Uruguay. The potential effects of human harvesting on the sympatric bivalve Mesodesma mactroides (yellow clam) and of salinity were analyzed through time and space (longshore variation). Inter- and intra-annual fluctua- tions of the different population components (recruits, juveniles and adults) were detected. D. han- leyanus showed uneven periods of abundance, with the occurrence of peaks of different magnitude that appeared related to fluctuations in the fishing effort targeting on the yellow clam. D. hanlepanus showed a marked longshore variability in population structure and abundance along the 22 km of sandy beach sampled Spatial variations in salinity and also in the amount of fishing effort exerted on Ad. mactroides seem to be key factors in explaining th~svariation. This study suggests that further research on sandy beach populations should include human activities as important factors affecting long-term trends. KEY WORDS: Donax - Bivalves . Sandy beach.

This study investigates food consumption and assimilation by the juvenile conch at different temperature regimes (22, 26, 30 and 34°C). Live samples of the juvenile conch were collected on several occasions between December 2013 to May 2105 at Merambong shoal, Johor Straits, Malaysia. They were acclimatized for one week in stocking aquaria with well-aerated seawater at 30 PSU, 26°C and fed with commercial marine sinking pellets. Prior to experimentation, the gastric emptying levels of the samples were standardized by allowing them to feed until satiation, followed by 24 hrs starvation. All treatments were carried out in ten replicates of similar sized aquarium (20 x 15 x 15 cm) containing 4L of aerated seawater. The conch food consumption rate was significantly different (p<0.05) between different temperature regimes. -

Fatty acids were quantified using gas-chromatography coupled with flame ionization detection (GC-FID), and the distribution of different fatty acids within lipid classes (neutral and polar lipids) was achieved after oil extraction using the Folch method and separation of lipid classes via solid-phase extraction for further GC-FID analysis. Red cusk-eel was the fish species with the lowest content of both EPA and DHA (40.8 and 74.4 mg/100 g, respectively) whereas mackerel contained the highest amount (414.7 and 956.0 mg/100 g for EPA and DHA, respectively). -
