Bottlenose Dolphin (Tursiops Truncatus) Behaviors In The Presence Of Active And Non-Active Shrimp Trawlers In The Mississippi Sound, Crysta M. Lorenz
Honors Theses
Bottlenose dolphins, Tursiops truncatus, are reported to have close associations with shrimp trawlers worldwide. The goal of this study was to assess differences in the behavior for bottlenose dolphins between activity states of shrimp trawlers in the Mississippi Sound. During active trawling, nets are actively gathering the catch closely behind the trawler, which provide feeding opportunities for bottlenose dolphins. Non-active groups are not able to take advantage of feeding prospects and display fewer feeding behaviors and maintain a farther distance than active trawler groups. Video of trawlers were collected from the Mississippi Wild Dolphin Project and analyzed for feeding …
