Not sure, and haven't researched it, but I'd guess that the reason there seems to be a 'dead zone' surrounding the Bahamas has more to do with the lack of nutrients washed from land, combined with wave action, than it does UV sterilization.

I had a boat on a lake in TX and carp would munch on the algae on the hull. It was a very strange sound at first until I figured it out.

My understanding is that the warmer waters of the Caribbean can’t hold as much oxygen as more northern, thus less life overall, and less biomass in the water.

This as opposed to the North Atlantic, which teamed with fish before we overfished everything. Nutrients flowing from rivers and estuaries help too no doubt, whereas Carribean isn’t as fertile overall (more volcanic/coral islands)

It’s said New York was paved with oyster shells, and the Connecticut river teamed with fish so thick you could walk across without getting wet. There was a law on the books allowing only ONE fish to be placed in each hole when planting corn. Can you imagine? Fish averaging over $10 per pound these days, and they used them as fertilizer.....

Lobster was used as fertilizer and to feed to animals

Tilapia eat the weed, and sea bream and snapper dine on the barnacles--as well as some other species--but without a picture it is hard to tell what they are. Tilapia and snapper are both edible. Some other species such as Bream are also--but there are some species I would not eat because of Ciguatera.

Photosynthesis is the base fuel for life

Any Ariel photo will show this
From Zero to two meters grass can’t grow , sun burn

the dark green in the picture , plus two meter depth , is an intense forest of grass

Probably more to do with sand mobility and the lack of nutrients than too much UV. Photosynthesis has to have sunlight.

Let's just look at these two main points of your observations. Certainly the intensity of light increases at lower latitudes; therefore by your explanation, we would have less growth in the tropics. The water moderates these higher temperatures, so that "prevents growth by burning" would be more prevalent on the land, yet look at the Florida Everglades at the same latitude as much of the Bahamas. There's less water depth and higher water temperatures and no dead zone. Store an open bucket of fresh water on your deck in low latitudes and within a week it will be green with thriving chlorella algae.

Let's look at grass growing in water depths from zero to two meters. Examples would be Card Sound, Barnes Sound, Blackwater Sound, and Buttonwood Sound. All these areas abound with Turtle grass in areas from 1 to 6 feet depths, but they are on the Bayside of the Florida Keys and are protected from wave action. 'and back to all that life on land that is not cooled by the water. If life can't survive light intensity of the tropics how can we have all this tropical growth?

I still see these zones of succession from the deeper water to the shore, but light killing off the organisms just doesn't work as an explanation

For all you eating Mullet, heres the trick to making them taste good all the time. When you catch them imediatly stick your fingers in there gills and break there neck so they bleed out. Guess you could cut there throat but snapping the neck is easy and quick. The bad flavors are in the blood. I am a 65 year old Florida cracker, born into a cracker family of mullet fisherman spending much of my life on a bayou were Mullet were a staple food. In my family any mullet that wasn't bled when cought was fertilizer or bait not suitable for the table. Try it you may be surprised how much better it taste, like bleeding out a shark and removing the cartlidge rings.

this was the fish.

my hull is now clean.

does anyone know what fish this is ?

I wish I could figure out why I can no longer see photos on CF. Must be my phone app gone bad. Anyway, is the photo of mosquito fish? They like to nibble. People use them for pedicures but that really tickles.

at 18 inches long I'd be worried about getting a pedicure from whatever fish he has though!

Well it ain't a mullet or a sheepshead. Looks pretty edible though...

I am curious too Arch, I think this is the same fish I saw schooling in Santa Barbara harbor a couple weeks ago and I could not ID it. They were surprisingly large too.
