Research has been carried out over a 10 month period with the aim of identifying potential sources of Salmonella contamination in a Mediterranean lagoon (the Thau Lagoon). Two types of source have been sampled, permanent ones which are checked monthly, and incidental ones. The highest occurrence of Salmonella is linked to episodic events brought on by rainfall. After summer low water levels, the rising of river water brings back into circulation water from pools previously formed by waste water from sewage treatment plants and sediments, thus creating a significant source of bacteria. The sewer system can also supply the Thau Lagoon with varying quantities of Salmonella when the system breaks down, and also when it is overloaded by an excess of rainwater following a storm. Monthly checks reveal that discharges of Salmonella occurred occasionally in permanent inputs, whereas the outflow from the Mèze pond provides a quasi-permanent, but negligible, source of contamination. The major risk of shellfish breeding contamination is thus associated with rainfall, and the occasional overflow of raw wastewater.The survival of Salmonella in the lagoon waters varies in function with the seasons, and the risk is greatest at those times of the year when autopurification can be affected.

Eriocheir sinensis, the Chinese mitten crab, is a native of east Asia and predominantly lives in freshwater but migrates seawards to breed. In 1912 a specimen was collected in the River Aller, a tributary of the Weser, Germany and now this exotic species has a European distribution from Finland to the Atlantic coast of southern France. In the UK, the mitten crab has been reported from the Humber, Medway and Thames catchments. Although the population in Thames had remained low, recent evidence suggests it is increasing, which has potential environmental implications.

The drainage of the Negro River is the most important watercourse in the Patagonia ecoregion and, together with the Colorado river basin, define an ecotone, i.e., a zoogeographic transition, where coexist the Brazilian and Patagonian lineages of freshwater fishes. The Patagonia ecoregion has 29 fish species, 15 native and the remaining introduced. For this study, the ichthyofauna of seven locations in the lower course of the Negro river drainage were sampled along two years. Gillnets, coastal trawls, cast nets, river trammel nets and fishing rods were used to catch specimens. A total of 13 species belonging to nine orders and 11 families were collected. The families Atherinopsidae and Characidae show the highest species richness and one exotic species, Cyprinus carpio Linnaeus, 1758, was recorded. The origin and distribution of some species is discussed, considering the role of human action and certain environmental factors.
