High capacity for extracellular acid-base regulation in the air-breathing fish Pangasianodon hypophthalmus.
The evolution of accessory air-breathing structures is typically associated with reduction of the gills, although branchial ion transport remains pivotal for acid-base and ion regulation. Therefore, air-breathing fishes are believed to have a low capacity for extracellular pH regulation during a respiratory acidosis. In the present study, we investigated acid-base regulation during hypercapnia ...

متن کاملIntracellular and extracellular acid-base regulation in the tropical fresh-water teleost fish Synbranchus marmoratus in response to the transition from water breathing to air breathing.
In the tropical fresh water fish, Synbranchus marmoratus, transition from water breathing to air breathing, induced by reduction of oxygen partial pressure (PO2) in the environmental water below 16 mmHg, causes a considerable rise in the arterial partial pressure of carbon dioxide (PCO2), from 5.6 to 26 mmHg on the average (half time of the rise between 2 and 6.5 h). The associated fall in arte...
متن کاملCarbonic anhydrase and acid-base regulation in fish.
Carbonic anhydrase (CA) is the zinc metalloenzyme that catalyses the reversible reactions of CO(2) with water. CA plays a crucial role in systemic acid-base regulation in fish by providing acid-base equivalents for exchange with the environment. Unlike air-breathing vertebrates, which frequently utilize alterations of breathing (respiratory compensation) to regulate acid-base status, acid-base ...
متن کاملRefined oil production from patin catfish (Pangasianodon hypophthalmus) by-products
In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The ...
