Leucocytes of anadromous and landlocked strains of Atlantic salmon (Salmo salar L.) in the smolting period

The results of the leucocyte analyses suggest that there are differences between the anadromous and landlocked strains with respect to what cell type is present in highest proportion in the leucocyte samples from head kidney and blood. The striking similarity between the strains is the profiles of proportions of B-cells and neutrophils in HKL and PBL during the smoltification period.
