Changes in the Saccus Vasculosus Epithelium During the Smoltification Process in Atlantic Salmon ( Salmo salar)
Abstract The changes that take place in the saccus vasculosus epithelium during smoltification of Atlantic salmon ( Salmo salar ) are described. The major cell type of the epithelium, the coronet cells, have a number (mean = 32) of spherical protrusions connected with a non‐motile cilium to the apic...
