Effects of time of day, water temperature, and water velocity on swimming by postlarvae of the American lobster, Homarus americanus
Date of Original Version
Mean swimming speeds ranged from c7 cm.s-1 in the "claws-apart' swimming mode to 13.2 cm.s-1 in the streamlined, "claws-together' mode. In the flume, total time spent swimming during a 30-min test period decreased as water velocity increased from 8 to 14 cm.s-1. Time spent swimming was greater during the day than at either dusk or night. Postlarvae spent very little time swimming at 15°C but significantly more at 21°C. Wild postlarvae were larger, heavier, and swam more rapidly than laboratory-reared postlarvae. Rapid, directional swimming by postlarvael lobsters may play a role in determination of distribution and recruitment to benthic populations. -from Authors
