Re: strange question fish and hull

Hey I could use those guys on my hull! They wont do any damage. We get huge Trevally here that like to do the same, but they're darned fussy eaters and prefer the non antifoul flavoured barnies growing on the floating dock.

Re: strange question fish and hull

I remember many times coming from the north and reaching Lake Worth Inlet. We would take a slip at Riveria Beach before crossing over to the Bahamas and the Parrot fish would swarm over our bottom cracking away the barnacles. We never saw barnacles growing on pilings in many areas of the Bahamas. I suspect this was due to the predator reef fish.
'messy eaters though, - they never removed the barnacle scale and left us to "do the dishes".

If hungry, it is possible to try yourself... possibly even without a Californian commercial licence

In gin clear water sunlight intensity , uv, prevents life from growing

The dead zone can be one or two meters down in some areas

Do yourself a favor and don't eat anything you catch out of the marina...

Re: strange question fish and hull

In the Caribbean little yellowtail snapper follow me along the hull when I break barnacles. They are so conditioned that they show up if I enter the water with the tools in hand.

Re: strange question fish and hull

Where are you and what does the fish look like? Around here, sheepshead eat barnacles, mullet eat algae; they're both good to eat (though sheepshed are a bit of a pain to clean, and some say mullet meat picks up taste from the environment they live in, most likely from their diet). 18" would be a pretty big one for either species, generally speaking, the smaller the fish, the less chance it's had to accumulate toxins, if that worries you.

Life abounds in the "gin clear" air and the "gin clear" water. There's plenty of growth in the shallow tidal zones and people living on the land are always running their lawn mowers. Many pilings without barnacles are coated with algae and sponges. Cassiopeia are growing in inches of crystal clear water and the barnacles are well protected from uv within their calcium-carbonate shells except for some part time sweeping of those feathery gills. Barnacles can thrive where they are exposed at low tide. I have also seen this "dead zone" in some places. You may have some leads to a good answer, but the idea that uv prevents life is too simplistic. Please add something to this for an explanation that might work.

Re: strange question fish and hull

Green and grey water is that color because it is full of life

Gin Clear water is clear because it has little


Too much light prevents growth by burning the organism ,

lack of light , photo synthesis , retards growth, starvation

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

Re: strange question fish and hull

Fresh Mullet are among the best eating fish there is, but it has to be fresh, I mean caught it a few minutes before supper. For some reason it’s best to clean them and let them soak in ice water for awhile, it’s seems to firm up most any fish’s flesh if you do.

Mullet that isn’t fresh is horrible, Mullet won’t bite a hook, you can catch them with a snag hook or a net, but they won’t bite a hook.
Mullet are often considered trash fish by those that don’t know better.

Yet I can take you by boat to places where the weed is attached to the bottom and penetrates all the way to the surface. I’d suspect wave action may be partially to blame for what you see in that picture.
However I would agree that most of the banks of the Bahamas is pretty much a dead zone.
