    Abstract

    The routine static toxicity test method for molluscan larvae is outlined. A new flow-through test method for molluscan larvae is presented with data from studies of halogen toxicity. The test involves containment of larvae in a mesh-covered chamber suspended in a small aquarium. The water in the basket is replenished every 7 min by raising and lowering the water level in the tank by means of an automatic tidal siphon. Improvements in the test system are under development.
