I was wondering if there was some sort of rule of thumb with regards to how much ammonia fish actually produce?

Interesting question.

Given that most ammonia is produced through the metabolism of the fish rather than from other sources I suspect it's a function of size, diet and activity.

Yea, that is deff the case. I thought there might be some general number, maybe per inch or gram of fish.

I hate answering a question with a question but is most ammonia not produced through respiration rather than metabolism? Or are the two linked???

Yes, respiration is an integral part of animal metabolism. No oxygen no energy.

I'm not an expert on fish biology but generally ammonia (or other nitrogen containing compounds) is the result of the breakdown of protein.

My understanding is that respiration involves the intake of oxygen and expelling carbon dioxide, so I'm not sure how respiration on its own would create ammonia for the reason endler2811 says. However most of the ammonia created by metabolism is excreted through the gills.

Anyone able to clarify this further?

Eyrie u are right about what respiration is, strictly by definition, but the CO2 (and ammonia and a whole bunch of other stuff) which is expelled is the end result of the breakdown of food so these two processes are very much interdependent. The only reason u need oxygen is so u can extract energy from organic compounds. Respiration does NOT create ammonia on its own, but then again on its own respiration doesn't actually do a whole lot of anything.

My understanding is that in fishes ammonia is produced via metabolism of proteins and excreted primarily through the gill membranes. I'd have thought that the amount produced would be dependant on the variables Mark suggested originally, plus other factors such as age, species, etc. so probably near-impossible to quantify.

Isn't respiration a metabolic process then? /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

Well thats disappointing /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> I hoped there was something like the one inch per gallon rule but alas, seems it will remain a mystery. Thanks anyway guys /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />

Respiration is a metabolic process, but if you just take the gas exchange into account without looking at the next step you could consider it as being detached from the general metabolic pathways.
