Report ; RM/33 Issued also in French under title: Méthode d’essai biologique : essai de survie, de croissance et de reproduction de l’amphipode dulcicole Hyalella azteca dans les sédiments et l’eau. Prepared by: Lesley Novak and Lisa Taylor. Cf. Acknowledgements. Includes bibliographical references (p. 116-136). "Revised methods now recommended by Environment and Climate Change Canada for performing sediment and water-only toxicity tests using the freshwater amphipod Hyalella azteca are described in this report. The endpoints for these tests are survival and dry weight of amphipods at the end of a 14-day test. This method also includes a reproduction endpoint over a longer term exposure (42 days). Key to successfully conducting the longer-term test is the recovery from sediment and accurate counting of the young of the adults at the end of the 42 day test, and as such, the 42-d methods include a performance criterion that requires laboratories to meet a specified % recovery. This revised version of Report RM/33 supersedes Environment and Climate Change Canada’s test for survival and growth in sediment using Hyalella azteca, which was published as Report EPS 1/RM/33 in January 2013. The sediment test is intended primarily for measuring the adverse effect(s) of freshwater sediments, although procedures for testing estuarine sediments (≤15‰ salinity) are also described”--Abstract, p. ii.
