|A setting sun means another night on the water.|
By Annie Anderson and Antonia Ash
This past June, researchers, students, and volunteers from all over the world assembled in The Bahamas for the 19th Bimini Biological Field Station’s (aka Sharklab) annual PIT lemon shark tagging program. It was an international affair with this year’s 29 participants hailing from South Africa to Brazil, from the US to the UK, Belgium, and finally France. Despite the blood sucking mosquitos and lightning illuminating the skies above, the crew rallied together to make PIT 2013 a year to remember.

For the past 18 years Sharklab has monitored the juvenile lemon shark population in Bimini. Scientists assess survival, growth, and mating characteristics of the lemon sharks in two mangrove-fringed nursery areas called North Sound and Sharkland.
|PIT lasts for 12 days|
Whether at North Sound or Sharkland, it is the tagging boat’s responsibility to ensure all the nets are set at the same time. Once they go in they must be checked every 15 minutes over a 12-hour period from dusk until sunrise.

After the long and tiring 12-hour cycle and as the sun rises the net boats haul their lines and all head back to the lab for a hearty breakfast prepared by the hard working home crew. All equipment is cleaned and the team then head to bed for a 6 to 8 hour nap before they must wake to start the whole process again.
Check back here tomorrow where we will describe what goes on at North Sound.
The Bimini Biological Field Station Sharklab depends on the efforts of dedicated volunteers to accomplish our research. Since its 1990 inception, the BBFS Sharklab has been host to thousands of volunteers from all over the globe. Annie Anderson blogs at Sharks Need Love.
