Officially law last year (see here), Nassau grouper fishing season is closed in The Bahamas from December 1st to February 28th. This is to help populations recover and stop unsustainable fishing practices on their spawning aggregations. Let us all do our part and help spread the word.
An exciting new publication just came out helping us better understand Nassau grouper populations in The Bahamas (article here). Using acoustic telemetry data, Dr. Craig Dahlgren and others recorded the movements of different sized Nassau grouper to examine when and where individuals would migrate to spawning aggregations. They found that individuals did not migrate to aggregation sites until they were 54 cm in total body length, suggesting a new and increased minimum size limit for fishing regulations on Nassau grouper. To illustrate, current Bahamian regulation permits a minimum catch size of 3 lbs (1.36 kg), which in our own work on Nassau grouper, we have found individuals to weigh over this amount at 43 cm, ~10 cm less than their potential size of maturation. Furthermore, their movement data also suggests that individuals migrating for the first time were slower than ‘seasoned’ individuals but their swimming speeds were similar on their return home suggesting migration movement behaviors may be learned.
A recent article from The Tribune 242 (Click HERE) discusses how Nassau grouper populations in The Bahamas are still under threat due to high levels of poaching on spawning aggregations despite a closed season that was established in 2004. A definite highlight in this article is how much effort The Bahamas is currently putting forth to reverse this situation, and […]
A substantially revised version of the fishing regulations app Fish Rules is out. It is really cool – check it out.
Here are some photos of our recent course we did with Friends of the Environment focused on shark ecology and conservation. This two day course was inspired to help educate students on the importance of the recent shark ban that prohibits commercial shark fishing and promotes a catch and release recreational program nationwide here in The Bahamas. Further, the course went […]
Check out this article summarizing the latest research regarding Clifton Bay’s impact on its nearby environment. Above are some photos from the garden during my visit in late April where I was impressed by the density and size of fish that use the garden and nearby patch reefs.

Good news! The Bahamian government has established a closed season (no fishing or possession allowed) for Nassau grouper from December 1st- February 28 this year and EVERY YEAR from here on out. You can read more about this closure here and here. This is great news for Bahamian coral reefs! We have posted about Nassau grouper before and you […]
