Wow! Is that at the aggregation site? It must take a lot of patience to count, measure, and tag all of those Nassau Grouper!!
All those grouper are amazing! To count, tag, and measure all of them must be hard, it does help that we have tons of cool tech though. I saw your post for the hawksbill turtle. You should see mine and try to count, tag, and measure all my words!
I noticed when the turtle was swimming it didn’t use its back find much, anyways does the hawksbill turtle use its back fins when it swims?
Good question. I’m not exactly sure about that. You could certainly ask one of the scientists today, though!
Why do some of the Nassaus’ have black tops and white bellies and others have the common brown vertical stripes?
Only some of them have black tops and white bellies because it isn’t the big “Grouper Moon.” Also if they all wore the same thing they would be kind of boring right?
Good question, Jade. Remember, they use their different color phases both for camouflage and communication. The trend seems to be, that the closer they get to the actual spawning night, the more we see of that bi-color phase.
Was the hula hoop grouper here this season?
We have not seen Hula this year. But we are keeping a look out!
There are so many fish!!!! It must be very difficult to count them all.
when you are diving do you ever have to catch the fish and if you do how?
Not typically. There have been years where they have caught and released several Nassau to tag the fish with acoustical tags. You can see video of Dr. Brice Semmens actually doing this in the Changing Seas documentary. Check it out!
Wow! That’s super cool. If there is a one of a kind Grouper do you examine it or bring it to a lab or do you just look at it when diving. Have there been times when you have seen unique fish that keep coming back to one place all the time?
Great questions, Namratha! Ask them during our live video conference this week!
