..claudin 27a and 30. It is possible that claudin 10e is an important component of cation selective channels, whereas reduction in claudin 27a and 30 may change permeability conditions in favor of the ion secretory mode of the SW gill...

..The effects of the tested hormones cannot explain the sum of changes induced by salinity, which, like the smoltification data, suggests the importance of additional factors and possibly contact with the imbibed SW per se. ..
