Abstract:

Species profiles are literature summaries of taxonomy, morphology, distribution, life history, and environmental requirements of coastal aquatic species. These are designed to assist in environmental impact assessment. The American lobster is a valuable commercial shellfish. After spawning, lobsters undergo a series of molts as adults they live in coastal and offshore waters. Lobsters are captured in baited traps and incidentally in trawls. About 5-6 million pounds were captured commercially in 1983, a downward trend from 1971. Major environmental factors affecting reproduction, growth, and survival are water temperature, oxygen concentration, salinity, and substrate. Author
