Carp's Heart Rate & Frequency

Adder_Noir

Hi,

I'm trying to find out what would be the expected pulse rate and frequency of emitted sound by a carp's heart beat where the fish is of size around 5kg (10lb) plus.

Does anyone know where I might find such information, or have a reasonable guess as to what it might be?

Q1:
The pulse rate is largely dictated by water temperature since carp are poikilotheric - cold blooded. In general, fish can "exert" themselves for short bursts of energy which would, I assume, elevate pulse rate for a short period of time. But because of available oxygen (carp are experts at living in water with low 02 levels) long term exertion will result in severe tissue oxygen depletion.

All this means is that virtually all the time the carp's pulse rate is dicated by water temperature.

Q2: I have no idea. Are you implying that pusle rate has something to do with heart sound frequencies?. By the way, you can google for heart sounds and see what heart sounds are like. Can't find any fishy references. Note: fish hearts and mammalian hearts are different.
