Copper is more toxic to all life stages of the copepod Tisbe than cadmium. The most sensitive life stage of Tisbe to both copper and cadmium is the one-day-old nauplius. The resistance of larval stages of Tisbe increases with age (one-day-old nauplii 48h mg Cu l−1. and 0.5384 mg Cd l−1, 0.3415 mg Cu l−1. and 0.645 mg Cd l−1. for five-days-old nauplii and 0.5289 mg Cu l−1. and 0.9061 mg Cd l−1. for ten-days-old nauplii. The two reproductive stages of Tisbe tested (females with ovigerous bands and females bearing the first ovigerous sac) demonstrated an increased sensitivity to metals and proved more sensitive than the ten-days-old copepodids (only females with ovigerous bands had a similar sensitivity to copper with the ten-days-old copepodids).
