Recent Grouper Spawning Aggregation Research

A recent post on the Shedd Aquarium website regarding Nassau Grouper spawning
.  These are truly spectacular events (here is one You Tube video).  I was
fortunate enough to  dive on one of the aggregations off of Andros in 1999, and it was
one of the most impressive things I have seen.  Grouper return to the exact
same places, year after year, on winter full moons, to spawn in these large groups.  It
remains a mystery why these particular sites are chosen.

The Bahamas should be commended for their repeated seasonal closures of the
Nassau Grouper fishery
.   An absolutely necessary step in maintaining the long term
viability of the Nassau Grouper fishery in The Bahamas.

Chuck Knapp, the expert on iguanas in The Bahamas, actually wrote the
grouper post.  Here is one of his recent papers from his iguana research on Andros.

Craig Layman
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.
