General Movement Patterns

Dolphin Movements by Geographic Location

In 2019, 51 dolphin movements have been archived for the Dolphinfish Research Program (DRP).  This is the third highest amount of movements ever recorded in one year for the program.  The top two years in terms of movements recorded were in 2007 and 2009, when 68 and 56, movements were logged, respectively.  Our most recent dolphin recovery was reported at the end of September by Lee Rose of Frankford, DE.  He recaptured a dolphin near Poor Man’s Canyon aboard the charter vessel Stalker 14 days after the fish was tagged and released by Captains Chris and David Jobes of the Pair of Docs fishing team.  Youth angler Will Jobes caught and tagged the fish.  This is the only in-region MAB movement logged this year and represents the longest southwesterly movement ever logged for the program in the MAB (see figure below).  The greatest observed time at large for a dolphin recovery in the MAB region is 56 days and no movements have ever been generated outside of the waters near Maryland or New Jersey.  With the DRP now based in Newport, Rhode Island, we aspire to change this next summer with the deployment of a few satellite tags.  Check out the information below to learn about more general movement patterns observed throughout the history of the DRP.

In an ongoing review of data collected with Dolphinfish Research Program (DRP) from 2002-2017, dolphin movement linkages between geographic locations are beginning to emerge.  This brief article is to serve as a visual review of some of the main movement linkages observed since the DRP started.

With more than 23,000 fish tagged by the end of 2017 the 571 recoveries generated from that 16-year effort has led to the world’s first look at dolphin movement linkages within the WCA by location.  In Florida alone, more than 236 in-state movements stand to reveal detailed movement dynamics by season and location, an analysis that is ongoing.  Below is a slideshow of some of the movement linkages observed to date.
