The cultivation of the Mediterranean mussel, Mytilus galloprovincialis Lamarck, 1819, has been tested in an innovative Integrated Multitrophic Aquaculture system (IMTA) Mar Grande Taranto, as part EU-funded Remedialife project. This farming method could solve several problems including low growth rate mesotrophic environments while reducing environmental impact fish mariculture. Three productiv...

The nitrogen and carbon stable isotope ratios (dN and dC) of the pygmy mussel, Xenostrobus securis, were determined for three estuaries with varying levels of catchment disturbance in northern New South Wales, Australia. The lower Manning River catchment supported the highest human population densities and 3% residential development with some livestock agriculture (41%); the Wallamba River catc...

With the aim of developing biomarkers of polycyclic aromatic hydrocarbon (PAH) genotoxicity for biomonitoring of the marine environment, the formation of DNA adducts and oxidative DNA damage was studied in the sentinel organism Mytilus. Mussels M. galloprovincialis were exposed for 21 d to different doses of benzo[a]pyrene (B[a]P) (50 and 100 mg B[a]P kg–1 dry wt mussel d–1) via trophic intake....

Japan's rice sector is supported by high prices paid by consumers that allow many farm households to maintain small rice farms. Japan's government controls trade within a tariff-rate quota and imposes a prohibitively high tariff on imports outside the quota. Within Japan, diversion programs pay farmers to substitute other crops for rice since, without government-mandated diversion, supply would...

Successes • Many people showed up at the public meeting. • The citizen group wants to continue beyond the MERIT project. • Increased level of knowledge on both sides of the table. • A deeper understanding of pesticide sources and precautionary actions. • Implementation of cooperative farming contracts is not only a question of money. • There are new opportunities to establish waterworks coopera...

1. The structure of a community is governed by a complex combination of processes whose relative importance varies over time and space. Larval dynamics, settlement and recruitment are thought to be important processes limiting adult abundance and distribution of benthic invertebrates with planktonic larvae. 2. Two invasive molluscs with similar morphology and resource needs, the Eurasian zebra ...

Hiroshima Bays is top production approximately 60% of oyster in Japan. For cultivate oyster, fishermen use hanging rafts. A thousand raft during 2-3 years the bay. Large-scale culture may change ecosystem structure and material cycles bay through filtration particulate matter by oysters other associated animals. This study described community marine organisme terms fishes surrounding animal att...

Microplastics with particle size less than 5 mm are becoming a raising global environmental crisis. These pollutants were found from the poles to equator, in continental shelves, coasts and oceans, moreover, they have also been identified water columns, sediments even variety of organisms. The majority microplastics that ended up oceans originate land. Due their small size, easily accumulated f...

Methods Lethal temperatures for M. californianus were determined using temperature-controlled chambers in which both the magnitude and duration of exposure were manipulated. Field surveys of the shore level and solar exposure of upper zonation limits of mussel beds were conducted at 15 sites. Measurements from the lethal temperature studies and field surveys were used with a biophysical model o...
