Fish With Attitude: Some Like It Hot

Science Daily: Fish with Attitude

 

Maybe if you have mean fish you should tell them to chill out...

I was just reading last night in an online story from Coral magazine about Vibrio (a bacteria) becoming more aggressive in warmer water and possibly being linked to massive coral bleaching events.

 

Vibrio Discovered to Have "Jekyll-and-Hyde" Characteristics

sooo -

 

does this mean we can change our livestock behavior in >80 vs <80 home aquariums?

I don't know. I've read that elevated temperatures can certainly shorten their lifespan by accelerating their life processes. (I don't know what the evidence is for that, though.)

 

I was wondering the same thing with the bacteria story, though.

Kim Ritchie at Mote has been working on this very thing. According to her presentation (if I recall correctly), the bacterial communities on the mucus layer of the coral shifts during bleaching events, with vibrios increasing in number post bleaching - this could also be one more vector for diseases to take over during times of stress. Very intereting stuff and shows that we are still learning the basics of these simple, yet complex animals...

Interesting. Is Kim's research showing a shift in the composition of the bacterial community? Is there a change in the composition or some quality of the mucus layer that attends this shift as well? I agree, there's a complex community that exists even at the surface of our corals that we may never fully appreciate. How is Dr. Ritchie's research funded, Mike, or do you know?
