Subject: Temp. vs. resp rate of fish question

I am a high school student in a phys. sci. class at Mt. Shasta High in No.
CA.  I am attempting to determine whether or not the temp. of water a fish
swims in influences the fishes respiritory rate?  In all the research I
have done so far  I have not come across any definitive answer yet.  Can
you assist me?  Thanks in advance.  Write me

Check out the following reference, it gives an equation for channel 
catfish respiration as a funtion of body weight and temperature.

dissolved oxygen concentration in channel catfish ponds. Transactions of 
the American Fisheries Society, 107:484-492.

As temp increases, dissolved oxygen decreases. Whether fish respond by 
increasing resp. rate likely varies with species (look at the difference 
between trout and catfish and their range of tolerance). A good person I 
can think of who might be able to help is Dr. Tom Miyuake (e-mail: 
[email-masked]). I'll inform him that your might e-mail and would be 
interested in knowing what his response is. If you can't get his e-mail 
to work, write me back.
