Juvenile Nassau Grouper Everywhere on Artificial Reefs

This short video is of one of our first reefs we built back in March 2009.  Please excuse the mess – crawfishers don’t seem to reassemble the reefs after their haul.  What was noticeable was the abundance of small Nassau grouper (5-24 inches).  Some of the reefs (just 40 cinder blocks) had as more than 20!  I can’t help but think this is related to the ban on Nassau grouper fishing in the winter.  Here is a video of another reef as well.

My lab’s interdisciplinary pursuits provide for a multi-faceted understanding of environmental change in the coastal realm. We are ecologists, asking questions that span population, community, ecosystem and evolutionary sub-disciplines. We often use a food web based perspective, exploring top-down (e.g., predation) and bottom-up (e.g., nutrient excretion) mechanisms by which animals affect ecosystem processes. All of our efforts are framed within a broader outreach framework, directly integrating science and education, using approaches such as this website.

    I shared this report, and someone on Tilloo Cay contacted me to say that in their bay – not one with artificial reefs – they had noticed the same thing, a notable increase in the number of NG juveniles. RH
