Effects of drilling muds on behavior of the American lobster, Homarus americanus, in water column and substrate exposures

Abstract

Studies were conducted to explore the effects of drilling muds on various aspects of lobster behavior directly related to survival in the field. Toxicity of different drilling muds varied from immediately lethal to adult lobsters to apparently harmless to postlarval stages, with a variety of intermediate effects. Both the chemical toxicity in the water column and the physical effects of covering the substrate with drilling mud were studied, and both interfered with normal lobster behavior. The studies are mainly concerned with postlarval lobsters (stages IV and V), just after settling on the bottom. They were tested in 36-d chronic exposures (7 mg/L) and in seminatural aquaria with 1-mm layers of drilling mud covering the substrate. Toxicity in the water column manifested itself in feeding and molting delays, severe delays in shelter construction, increased walking and swimming, unprovoked tail flipping, and lethargy. A natural bay mud used as a control caused no such effects. Physical effects of substrate cover were apparent in experiments with 1-, 2-, and 4-mm layers of drilling mud and similar layers of a mixture of bentonite and barite covering a natural mud substrate. In depths of 4mm both kinds of substrate cover caused severe delays in shelter  More>>

Thus, substrates with 4-mm to perhaps as little as 1-mm covering of drilling mud may cause increased exposure of lobsters to predators and currents, resulting in the substrate becoming unsuitable for lobster settling and survival.}
