The Migratory Habits Of The Salmon

Author: Top of the Rock Astronaut / Labels:

The instinct with which the salmon revisits its native river, is one of the most curious circumstances in its natural history. As the swallow returns annually to its nest, so it returns to the same spot to deposit its ova. This fact would seem to have been repeatedly proved. M. De Lande fastened a copper ring round a salmon's tail, and found that, for three successive seasons, it returned to the same place. Dr. Bloch states that gold and silver rings have been attached by eastern princes to salmon, to prove that a communication existed between the Persian Gulf and the Caspian and Northern Seas, and that the experiment succeeded.
