TOXICITY EXPERIMENTS ON BARNACLE AND BRINE SHRIMP LARVAE

The investigation was designed to evaluate the toxicity of mercuric chloride for Balanus amphitrite niveus under standardized, controlled conditions, as a part of a worldwide investigation of the resistance of a variety of fouling organisms to this toxicant. 300 Balanus cyprids and 900 control Artemia salina larvae were exposed to mercuric chloride concentrations of 10, 100, and 1000 mg/1 in 2.1% C1-sea water. The LD sub 50t for Balanus at 1000 mg/1 was 120 minutes; at 100 mg/1 it was 225 minutes; and at 10 mg/1 it was more than 500 minutes. Artemia larvae at the same mercuric chloride concentrations showed LD sub 50t's of 135 minutes, 285 minutes, and more than 500 minutes. Artemia larvae were significantly more sensitive to mercuric chloride when the chlorinity was reduced to 1.8%.(Author)
