Heart rate and emitted sound frequency of carp's hearbeat

[adder_noir]

Hi,

Do any of you Biological-scientist-type-guys know where I can acquire the information stated in this thread title? I'm thinking of building a detection device for them using their heartbeat as the signal I'm trying to detect.

So does anyone know what their general pulse rate is, and what frequency band the sound emitted by their heart beat is?

Couldn't think of anywhere else that would have this kind of info

I thought I'd wait a bit and see if anyone answered this, but as they havent they must be thinking the same as me: this is a logistical nightmare.

I'd probably try to read up a bit of human ultrasound techniques to get started - an easy search in google - if you really wanted to pursue this.

Very nice idea though.

Thank you for the reply

i do not understand it very well were is the point

Carp heart rates vary with ambient water temperature; slower for lower temperatures. Also some carp exhibit lowered heart rate in hypoxyic conditions. Here's a paper that looked the effect of hypoxyic conditions on a carp heart that gave heart rate as 50-90 bpm. As well as producing some graphs that may be of interest to you.

You may want to search for similar papers regarding carp heart rate (or metabolism) in response to temperature.

In general, fish hearts are two-chambered, different from humans 4-chamber hearts.

I'm curious, may I ask why you are making a device to detect carp by listening to their heart beats?

Thank you for your reply CoffeaRobusta

It is for finding carp in zero visibility water on shallow waters in northern england. They are very hard to detect and there is very little known about their behaviour and location, especially in the canals and rivers.

I thank you again

It's sounds much like something from the film 'Predator'. Really nice idea, but personally I think sonar is as good as it gets (for now).
