Case Study – Atlantic Salmon
Atlantic Salmon are a fish species native to the North Eastern and North Western coasts of the Atlantic Ocean. This Anadromous fish species spends 1-3 years in freshwater rivers before moving to sea, traveling to the coast of Greenland and feeding for an additional 1-3 years. During this marine growth period fish become reproductively mature and return to native rivers to spawn. Most fish spawn and die but few are iteroparous, having the ability to “drop-back” or return to sea, before having another freshwater spawning bout.
