Experimental assessment of oyster transfers as a vector for macroalgal introductions 5
Mineur, Frederic; Belsher, Thomas; Johnson, Mark P.; Maggs, Christine A.; Verlaque, Marc.
Introduction of non-indigenous species can alter marine communities and ecosystems. In shellfish farming, transfer of livestock, especially oysters, is a common practice and potentially constitutes a pathway for non-indigenous introductions. Many species of seaweeds are believed to have been accidentally introduced in association with these transfers, but there is little direct evidence. We experimentally simulated the transfer of oysters from the Thau Lagoon (France). These transfers involved increasing periods of aerial emersion and additional brine and hot water treatments. The brine and hot water treatments were evaluated as a means of reducing the probability of algal introductions with oyster transfers. Shells were cultured for 40 days in...

Native species exploited by marine aquarium trade in Brazil 49
Gurjão,Lívio Moreira de; Lotufo,Tito Monteiro da Cruz.
Abstract: Brazil has an important role in marine ornamental trade, exploiting native species for both international and domestic market. A few works have previously assessed wild species exploited by the Brazilian marine aquarium industry and most of them focused solely on fish. Hence, the present paper intends to address an information gap regarding the species currently traded in the country, as well as concerning their conservation statuses. Thus, different sources of information were investigated and each species was categorized in accordance with existing lists of threatened species. A wide variety of native species was identified in Brazilian marine aquarium trade, including not only fish but also invertebrates, seaweeds and macrophytes. Some of...
