Statement of Problem: A series of consecutive 96-hour acute toxicity tests will be conducted with early life stages of white sturgeon and rainbow trout starting with about 1 dph fish to about 90 dph fish (Table 3). The toxicity tests will be conducted in accordance with guidance provided in ASTM (2009a). Test conditions for conducting the acute toxicity tests are summarized in Table 4. Table 5 provides a listing of daily activities for conducting the acute toxicity tests. Tables 7, 8 and 9 provide a summary of measures of water quality and metal chemistry for water samples collected from the acute toxicity tests. Table 10 provides a summary of test acceptability requirements for the acute toxicity tests.
Objectives: Conduct acute toxicity tests with sturgeon and trout.
