Abstract
    A bioassay with the hydroid Hydractinia echinata was developed in order to assess the toxicity and environmental impact of low-reacting compounds like organosilicons or hydrocarbons. The hydroid's response to the toxicant was measured by the changes in its feeding rate. This technique is relatively easy to undertake, rapid, accurate, and not expensive.
