摘要: Intestinal nutrient transport in yearling coho salmon was characterized and adaptive changes were described relation to development, starvation, environmental salinity. Salmon intestine exhibits a small transepithelial potential difference (TEP: −1.4 2.0 mV, mucosa ground) low resistance (41 181 ohms·cm2) that varied with the region along intestine, Addition of glucose or proline mucosal side caused rapid increase short-circuit current. Isotopic mucosalto-serosal net fluxes achieved across absence chemical electrical gradients. A sleeve technique for measuring influx (Karasov Diamond 1983a) validated use intestine. Comparison total different intestinal regions showed following order (from highest lowest rates): pyloric caeca ≫ anterior > posterior Total April during parr-smolt transformation.
