Rapid temperature-dependent wound closure following adipose fin clipping of Atlantic salmon Salmo salar L.
Three groups of Atlantic salmon were kept at a constant temperature of 4, 10 and 14 °C. The adipose fins were removed; six fish/group were sampled at 11 subsequent time points post-clipping. Samples were prepared for histopathological examination to study the course of re-epithelization. A score she...

Three groups of Atlantic salmon were kept at a constant temperature of 4, 10 and 14 °C. The adipose fins were removed; six fish/group were sampled at 11 subsequent time points post-clipping.

Wounds were covered by a thin epidermal layer between 4 and 6 h post-clipping at 10 and 14 °C.
