| The clam fishing and aquaculture system in the Venice Lagoon still appears insufficiently resilient to buffer external and internal perturbations, such as productivity fluctuations, unregulated fishing, and market related dynamics, despite the efforts of regional and local authorities to achieve the sustainable development. According to the System Approach Framework (SAF), based on previous studies and stakeholder interactions, we developed a model integrating ecological, social, and economic (ESE) aspects. We chose the aspects necessary to represent the essential dynamics of major ecological, social, and economic clam farming system components to project the consequences of implementing alternative management policies and to address the ecological and... |

| As part of a larger project financed by the European Union programme "Community initiative PESCA" on the study of "small scale fisheries" in Aquitaine (France), an estimation of the stock of clams in the Bassin d'Arcachon has been conducted. A two-stage stratified random sampling survey has been designed. Samples have been collected using a Hamon bottom sampler in 237 locations distributed over 24 km2. The clam Tapes philippinarum, which appeared in the basin following a series of aquaculture experiments in the mid eighties, is now the main species accounting for more than 90% of the abundance and the biomass, largely overcoming the European species Tapes decussata. The mean abundance and biomass (26 clams / m2 et l28g / m2) are above those estimated in... |

| A bibliography of over 1,400 papers on reproduction, recruitment, genetic, pathology, basic biology, and the geographic distribution of the Manila clam Tapes philippinarum is compiled to provide a guide to scientists. This review aims to facilitate access and diffusion of scientific works carried out on this species to the international scientific community concerned by Tapes philippinarum. The bibliography includes publications as well as grey literature published around the world since the early century. Moreover, the large synonymy of Tapes philippinarum and the species geographic distribution are reviewed and updated. The species importance is assessed through public fishery landings and aquaculture production per country. The D'v'eral1 worldwide... |

| The Pacific Mani la clam (Tapes philippinamm) was introduccd in France be tween 1972 and 1975 by the SATMAR Corporation , and in England through the Conwy Laboratory in 1980. Initially. spat were introduced and later adults, both from the west coast of North America (Puget Sound area). Aquaculture production in France started from adults. Until 1975, experiments with the spat were conducted at half-industrial scale and research activities and plans to transfer the knowledge were set up. The breeding began at first on the French Atlantic coast in intertidal areas and at the same time in oyster ponds. Characteristics of the new cu lture are presented in th is paper. The diseases met wilh in larval production and growout are also discussed . Nalural... |

| Different treatments aiming to cure the grounds, which bad been contaminated by the vibrio P1 "brown-ring", have been carried out on some sites of on-growing, taking place in the Aber Benoit, in Brittany. The tested products were Lime, and an antiseptic "Agroseptil" which positive effects are admitted in pisciculture. The results (growth, survival and the presence of brown-ring), do not point out any difference between the various treatments. However, it looks as if the brownring has appeared latter than on other clam-fields located in the same area.This effect does not seem to be due to the various treatments of the soils, but to the antibiotic bath of the clams bef ore seeding. |

| A bacterial strain belonging to the genus Vibrio was involved in a recurrent outbreak of disease in Manila clam Tapes philippinarum larvae at a commercial hatchery, This vibrio, named VTP for convenience, was not related to the known pathogenic vibrios and possessed unusual characteristics, Only Manila clam larvae and postlarvae were affected by the disease, Oyster and scallop larvae were not affected by vrp, Survival of vrp was found to be of short duration in seawater but even a very small number of cells (1 cell per 5 ml) could initiate the disease, VTP did not grow on thiosulfate-citratebile-sucrose agar and was resistant to chloramphenicol. An epidemiological study utilizing bioassays revealed the presence of VTP in adult bivalves and in the... |

| During the last 20, years, intensive mollusk farming has been developed in coastal waters, mostly in sheltered bays and lagoons. Often, mollusk stocks are threatened by frequent anoxic events from macroalgal blooms. Here, a decision support tool is described to select the optimal short-term strategy to control algal biomasses. Even though long-term and detailed studies of the lagoon systems are required to provide reliable, biologically based policies, we have here developed a simplified analysis that overlooks most of the ecological complexity, but explicitly includes environmental variability and uncertainty in parameter estimation in the economic assessment of the performances of different management strategies. The aim is to quickly screen management... |
