Physiological and morphological investigation of Arctic grayling (Thymallus arcticus) gill filaments with high salinity exposure and recovery

Arctic grayling develop an interlamellar cell mass (ILCM) in their gill filaments when exposed to a half-strength seawater saline exposure but can recover if a freshwater environment is re-established within 48 h post saline water exposure. Microscopy analysis reveals that ILCM development is associ...

Description
Summary:Arctic grayling develop an interlamellar cell mass (ILCM) in their gill filaments when exposed to a half-strength seawater saline exposure but can recover if a freshwater environment is re-established within 48 h post saline water exposure. Microscopy analysis reveals that ILCM development is associated with a salinity-induced immunologic response.
