  8. 8. Now we have learned about the anatomy of the salmon...how do these enable the salmon to survive?
  9. 9. gills The salmon takes water into its mouth and pushes it out through the gills. The blood vessels in the gills extract oxygen dissolved in the water as it is pushed out through the gills. Allowing the salmon to breathe nostrils The salmon uses its nostrils to smell scents in the water, to sense danger and also recognise the familiar sent of their home stream. Allowing the salmon to smell and helps with safety and navigation
  10. 10. Scales and skin cover the salmon. Scales are small, hard plates which over-lap and protect the salmon from predators and bruising. The lateral line is a line of cells along each side of the salmon which is extremely sensitive to pressure and allow the salmon to sense movements and objects in the water. Scales begin to grow when salmon are very young and show annual growth rings, like trees. If scales fall off, salmon are able to grow new scales.
  11. 11. The 6 bony fins on the salmon aid with the salmon’s balance and steering. The tail fin also helps the salmon push through the water. Female salmon use the tail fin to dig the redd in which they lay their eggs. Did You Know... The small, fatty adipose fin is cut off by the salmon farmers at the River Bush fisheries in Bushmills in order to identify their fish from other Atlantic salmon.
