We have several research projects focusing on greater amberjack (Seriola dumerili) (“AJs”) in the Gulf of Mexico that rely on tagged AJs being recaptured and reported by recreational and commercial fishers.  These include:

 

Seasonal Movement and Mixing Rates of Greater Amberjack in the Gulf of Mexico and Assessment of Exchange with the South Atlantic Spawning Stock

 

Our overall goal in this project is to examine the seasonal pattern and rates of movement of greater amberjack in the Gulf of Mexico (GOM) and to determine the potential mixing rate of the Gulf of Mexico greater amberjack stock with the South Atlantic greater amberjack stock, especially in known spawning areas off southern Florida. 

 

To do this, we have captured and tagged AJs with yellow dart tags and then released them.  Fish have been tagged from Louisiana to the Florida Keys. We record the specific location and fork length of all fish released, along with capture information (depth, hook type, hook position, injuries, etc.).  When time permits, we also non-lethally sex the fish and collect some finrays from its pectoral fin for later aging and genetic analysis.

 

To determine the timing of any seasonal dispersal or migration patterns of GOM greater amberjack, it is important to get the tags from recaptured fish back.  It is also critical that the specific location of any recapture AJ is given so that we can determine its movement rate and distance moved.  This also allows us to determine if male and female AJs, and the different ages of fish, are moving in different areas or during different times of the year.
