Historical mining activities cause widespread, long-term trace metal contamination of freshwater ecosystems. However, measuring bioavailability has proven difficult, because it depends on many factors, not least concentrations in water, sediment and habitat. Simple tools are needed to assess bioavailabilities. The use biomonitors been widely advocated provide a realistic measure. To date there ...

The first Chilean species of Bogidiellid amphipod, Patagongidiella wefkoi n. sp., is described from freshwater springs in the Osorno Province, Los Lagos Region. The new taxon is characterized principally by the structure of the hypertrophied facial robust seta present on the peduncle of male uropod 1, and the modified dimorphic setae on the exopod of male pleopod 2. The new species is described...

The European lobster, Hommarus gammarus, is a commercially important species in Europe. Despite successful stock enhancement programs during the last two decades, culture methods of H. gammarus are still progress. In this study, effects pseudo-green water technique and clear with lower stocking densities on growth survival larvae stages I-IV were investigated. All reared 800 L cylindro-conical ...

The successful establishment of European lobster (Homarus gammarus) land-based production is hampered by the high mortality rate during larval development, which can be partially explained proliferation pathogens in communal tanks commonly used for rearing. Therefore, disinfection water treatment could improve low survival rates frequently recorded H. gammarus farming. In this study, we evaluat...
