Paralized and dead fish

I was walking on the beach at Ft. Lauderdale, Florida and noticed quite a few fish that got stranded and seemed paralyzed. I then noticed these huge blue bottles that got washed out. They are about the size of a size 5 to 7 shoe. Could it be that these fish were victims of the blue bottles?

was the water colder than usual?? I've seen the same happen on the west coast if there is a sudden overnight drop in water temp, specifically if it's a shallow bay.

Maybe some oke on a Cigarette boat dumped his stash overboard when the Coast Guard tried to bust him.

They OD'd IMO.

Sorry guys, I couldn't resist.:fbash:fbash
 
I'd be worried if it was temperature related. The tropics are normally pretty consistent in water temperature, only tolerating a degree or so fluctuation either side the 24degC mark.

well u are in bermuda triangle space, maybe they got abdusted by aliens who experimented on them and paralised them..... it is america after all.

Interesting that all three fish posted are from a similar family... Trigger ( Looks like an oceanic ) Scrawled Filefish, and a Boxfish....

"Bluebottle" looks like a Portugeuse Man of War at that size....

I didn't inspect every fish but the Triggerfish where the most common victims. In a two km stretch there must have been at least 10. O and I saw a Manatee as well, very difficult to get a good pic of these guys.

Fish kills reported in Florida, apparently due to cold spells; fishing restrictions set
By Press-Register staff
January 22, 2010, 7:25PMProlonged freezing temperatures over much of Florida earlier this month have caused massive fish kills from Miami to Pensacola, Fish and Wildlife Commission spokesman Lee Schlesinger said in a Pensacola News Journal report.

In Gulf Breeze, Fla., for example, tens of thousands of dead fish have floating in the canals of the Polynesian Islands subdivision in Gulf Breeze. "The entire surface of the water was covered yesterday," Clive Knights of Kalakaua Court said Thursday.

Fish kills from extreme weather conditions are not unusual, but this could be one of the biggest in recent history, Schlesinger said. As a result, the commission has set temporary fishing restrictions on tarpon, snook and bonefish as scientists evaluate the scope of the kill and decide if more conservation measures are needed.

The blue bottles was the first sign.... in certain places in our coast, blue bottles are a sure sign that very cold water is also around. I learnt this from an old angler in Mosselbay. The time in Dwarskersbos it was jellyfish... we even found a small sunfish dead on the shore.

I've read that the Jellyfish come here in the warm currents.

Generally the "old school" anglers say they are a good sign and as soon as they go away expect lots of tight lines because the warm water is here. I haven't had lots of tight lines though! Go figure.

I just found it rather interesting, yet alarming, that oceanic fish are so susceptible to cold spells. The state of Florida has imposed strict fishing regulations until researchers have figured out the extent of the nock that fishing populations have taken. Global climate change ???  This makes one ask many questions!
 
The ice cold run off from the North lying glaciers, carried into the tropics by ocean currents perhaps? If anything should raise eyeballs, it should be any untoward changes in the tropics. Like you get your indicator species , eg. golden-horn caddis lava and other highly susceptible to change insects, invertebrates and organisms that only survive in the most pristine unpolluted environments, so to should anything untoward in the tropics be regarded as a key indicator to environmental change. It's really scary when you hear of the coral reefs being bleached and tropical fish washing up due to cold snaps. Only in the last decade!

Good to hear that worldwide authorities and leaders are finally starting to take the global warming thing seriously. I just hope it is not too late.
