When I was a child in the first grade my daddy would fish the Snake River near Blackfoot Idaho. He sometimes allowed me to tag along and would catch stupendous fish such as trout and salmon. I never forgot those forays into the cold morning wilderness dressed in my warm coat and just how productive that time was from a food gathering standpoint.
You never know how much you're going to miss someone when they're gone. Be gentle with the feelings of those for whom you care.
Fish migration is one of those wonders that some never see. These traveling aquatic denizens are indigenous to those waterways which connect to the sea. Landlocked species are pretty much left to their own devices where they exist.
Today is World Fish Migration Day. It happens every other year on May 21 since 2014. The day is meant to bring attention to both migratory fish and free flowing rivers. It makes note of the migratory act as inherent to their reproduction, feeding, and completion of their life cycle.
The World Fish Migration Foundation maps fish migration routes and identifies those areas most significant to the various migratory species.
