JOURNAL OF AQUACULTURE - 2017 - About Through-Cultivation of Two Commercial Bivalve Molluscs. Appl. Environ. Microbiol. September 2005 Artificial Neural Network Prediction of Viruses in Shellfish. ANN versus MLR modeling.Predictions of viral presence in shellfish require models and indicator system that are capable of precision and accuracy in predicting viral presence for the protection of public health without undue burden on the shellfish industry.
The large amount of uncertainty that exists around simple linear regressions obtained from single indicator systems cannot be tolerated for these types of public health policy decisions. The degree of uncertainty must be reduced, and MLR modeling has been a large step forward in this goal. However, the underlying patterns between multiple, often interrelated indicators and pathogen risk are very complex and require a modeling system that can correctly capture this complexity without losing precision, precisely the attributes ANN models have been designed for. There are several things to consider when comparing conceptually dichotomous classification models.

Ocean & Coastal Management Volume 130, October 2016, Measuring the impact of pollution closures on commercial shellfish harvest: The case of soft-shell clams in Machias Bay, Maine. Open Access Abstract Temporary closures of polluted coastal waters to shellfish harvesting protect human health but also generate broad socioeconomic impacts on rural, fishing-dependent communities.
Improved understanding of these impacts could help coastal managers prioritize investments to protect water quality and mitigate the effects of coastal pollution. Using a regression model of monthly landings, we explore the impact of temporary closures on the commercial harvest of soft-shell clams (Mya arenaria) in the Machias Bay region of Maine (USA). We find that economic losses are significant and depend heavily on tidal activity, and the size, frequency and timing of closures.

NATURE 22/06/16 Infectious shellfish cancers may jump across species The parasitic tumours showed up in clams, mussels and other bivalves.
David Iglesias Transmissible cancers have been found in shellfish, including cockles (Cerastoderma edule) collected in Galicia, Spain.
Some clams, mussels and other bivalve molluscs carry infectious cancer cells that can leap between individuals — and that may even have jumped between species. The discovery, reported on 22 June in Nature1, means that transmissible tumours have now been found in six organisms. Two are well known in mammals: a facial tumour that threatens to wipe out Tasmanian devils (Sarcophilus harrisii) and a venereal cancer found in dogs all over the world. Nature Podcast Reporter Ewen Callaway finds out about the first case of transmissible cancer between species. “We thought these things happen now and then in nature, but that this was a fluke. Shell shock After the discovery, Goff’s team reached out to marine biologists to see whether transmissible cancers were prevalent in other molluscs. Barriers to entry “This is the first time that’s ever been seen,” says Goff.

PLOS 21/05/13 Food-Borne Disease Outbreak of Diarrhetic Shellfish Poisoning Due to Toxic Mussel Consumption: The First Recorded Outbreak in China. Abstract Objectives This investigation was undertaken in response to an outbreak of suspected shellfish poisoning in Zhejiang Province, China.
The objectives of this project were to confirm the outbreak and to identify the aetiology, source and mode of transmission. Methods A probable case was defined as an individual with diarrhea (≥3 times/day) plus at least one of the following symptoms: fever (≥37.5°C), vomiting, or abdominal pain after consuming seafood between May 23rd and May 28th, 2011. SpringerPlus 2014, 3:265 Occurrence of Vibrio and Salmonella species in mussels (Mytilus galloprovincialis) collected along the Moroccan Atlantic coast.
The major objective of this study was to determine the prevalence of potentially pathogenic Vibrio spp., Salmonella spp. and E. coli in mussel (M. galloprovincialis), collected from Agadir and Essaouira coastal areas that vary in water temperature and salinity.
Vibrio spp. was found in all the sites, with percentages ranging from 7.7% to 100%. Compared to the other reports which investigated the mussels (M. edulis and M. galloprovincialis), the percentage of Vibrio-positive samples in the present study was higher than the occurrence found in previous studies carried out in Germany (Wadden Sea: 74.4%), Ionian (Mar Piccolo of Taranto Sea: 60%) and Italy (Adriatic Sea: 48.4%) (Lhafi and Kuhne 2007; Cavallo and Stabili 2002; Ripabelli et al. 1999). The difference obtained between our results and these reports may be associated with the existence of different climate conditions in the different areas.
Except Cap Ghir site, Salmonella spp. was found in all sites.
