Reduced salinity tolerance in the Arctic grayling (Thymallus arcticus) is associated with rapid development of a gill interlamellar cell mass: implications of high-saline spills on native freshwater salmonids

Arctic grayling were exposed to water conditions similar to industrial saline water spills. Grayling demonstrate a greatly diminished tolerance to seawater compared to euryhaline rainbow trout. Development of a novel response, a gill interlamellar cell mass, occurred within 24 hours in response to 1...

Description
Summary:Arctic grayling were exposed to water conditions similar to industrial saline water spills. Grayling demonstrate a greatly diminished tolerance to seawater compared to euryhaline rainbow trout. Development of a novel response, a gill interlamellar cell mass, occurred within 24 hours in response to 17ppt (50% seawater) exposure.
