A potential new estuarine amphipod test species from Europe
- Univ. de Aveiro (Portugal). Dept. Biologia
Sediment toxicity testing is of recognized value, however tests do not exist for all ecoregions. In particular, there is a paucity of test species for estuarine conditions. To date such testing has been conducted using either Microtox or the Pacific amphipod, Eohaustorius estuarius. There are no other test species for which developed tests exist, which can tolerate the full range of estuarine salinities (0 to 35 ppt). The authors report testing with the Atlantic amphipod, Corophium multisetosum, which can survive well from 0 to 35 ppt. At the time of writing this abstract, initial testing has indicated appropriate dose-response relationships with the reference toxicant cadmium chloride, and an acute 10-day protocol has been successfully conducted at a range of test temperatures (15--22 C) and with salinities of 0.0, 0.2, 0.4, 0.8, 1.6, 3.2, 6.5, 12.5, 25.0, 50.0 and 100.0%. Work presently underway and expected to be reported at the World Congress includes finalization of methods development for acute (10-d static) testing, namely the sensitivity to a range of fines content in the sediment, and initiation of chronic (growth, reproduction success) testing.
