2. Due to industrialization, urban growth, unplanned farming, deforestation, and pollution would have imparted strains on the stocks of salmon. Apart from this chemical contamination from the industrial run-off and agricultural activities are also declining populations of salmon.
3. Genetically modified fish from hatcheries usually escape and interbreed with wild fish, thus, changing the genetic features of the populations.
4. Construction of hydropower dams is also a major cause of the salmon population declining.

Answer:
A. Cadherins in desmosomes would no longer be anchored to intermediate filaments
Explanation:
Cadherins are Ca dependent molecules (proteins) that are involved in cell-cell adhesion (they are type of cell adhesion molecule-CAM). Cadherins are composed of: a small cytoplasmic component, a transmembrane component, and the extra-cellular part.
There are types of cadherins called desmosomal cadherins which are involved in the formation of desmosomes (structure for cell-cell adhesion) and they bind to linker proteins and keratin intermediate filaments.
