factors affecting respiration rate

Cleanup

Okay, good start. Some decent information, but it's a little unfocused, not cited properly, and not enough. I think the best thing for this article would be for someone who knows the topic to take it and incorporate the existing info into a whole new format. Docmcconl (talk) 04:19, 13 May 2008 (UTC)

"One of the main characteristics of aquatic respiration is that, just like terrestrial respiration, it is done through the anus."

I'm not sure that respiration is done through the anus on land or underwater. --Cremela (talk) 21:35, 17 November 2009 (UTC)

"In fish, the long bony cover for the gill (the operculum) can be used for pushing water. Some fish pump water using the operculum."

I think it needs to be clarified what the operculum does. Does it push or pump water or maybe in this case neither because it doesn't seem to be the right choice of word to use. It's also not clear on the purpose of the operculum pushing water or the need for fish to 'pump' water. Also someone should wiki operculum and see if they use the info on that page to fix the info here. Donfucius (talk) 11:20, 26 December 2009 (UTC)

Added 4 citations for "Fish" respiration section. Fixed some grammatical errors, and added information about the Spiracle and the Splanchnocranium to the same section as well. — Preceding unsigned comment added by JohnKGII (talk • contribs) 12:43, 7 June 2019 (UTC)

Exhalation

The process of exhalation is completely missing from this article! Am I right in assuming that inhaled oxygen is exhaled, after performing its biological functions, as carbon dioxide gas, produced via carbonic anhydrase from bicarbonate in the blood?Petergans (talk) 12:09, 29 October 2020 (UTC)

I have revised some of the text to better reflect the processes. Oxygen is taken up by respiratory pigments in the blood having moved across the gill (or equivalent) interface by diffusion. Waste gases and potentially other solutes are lost to the water body by diffusion from the same interface. The precise metabolic derivation of carbon dioxide isn't addressed and is probably not needed here.  Velella  ^{Velella Talk}   14:18, 29 October 2020 (UTC)

Thank you for this reply and your extensive revisions of the article. The reason for my interest is that I'm revising the article on carbonic acid. The current draft of the relevant section is in my sand box. Obviously there should be a link to aquatic respiration. As things stood, there would be no point in such a link. The key issue is the role of carbonic anhydrase in facilitating the removal of the CO₂ created by metabolism of inhaled oxygen, from the biosphere. Can you suggest a biochemical text-book or treatise that could be cited? Incidentally, there is an interesting symmetry between in- and ex-halation. Inhalation of oxygen is mediated by hemoglobin-type molecules to facilitate the transfer of gaseous oxygen to the biosphere. Petergans (talk) 10:49, 30 October 2020 (UTC)

Sorry but that is not my area of expertise. My post grad qualification was in hydrobiology, and that over 50 years ago. Biochemistry has changed, just a little, in that time, so any advice that I could offer would be more antiquarian rather than relevant. Apologies.  Velella  ^{Velella Talk}   13:19, 30 October 2020 (UTC)
