I can't imagine that to be an effective tactic. Looks too much like skeet shooting opportunities for the enemy.
I have salmon and trout spawning in my backyard. I see this every year, but some runs are heavier than others and sometimes the state takes the salmon for roe and milt for the hatcheries. I have fished on the Copper River, but we can do it with a net since we are residents. By the way, salmon this red are particularly good eating.
I had always heard that salmon were too soft to eat once they had turned red for spawning, so that is not true after all ?
Different species turn red differently, but, yes, generally you don't want to eat a salmon that has turned red. Some pink tinge is usually okay though.
Red salmon is a species of Pacific salmon, also called Sockeye salmon. It is the richest meat. King, or Chinook salmon is the largest and the fattiest. Silver, or Coho is generally frozen here. Dog salmon, also called Chum, is one prized by the Natives and the hardiest as it is the only one found above the Arctic Circle, and finally Humpy, or Pink salmon are the most numerous and usually caught only in saltwater, as the coloring begins as soon as the fish hits any brackish water and the fish is generally not considered edible by Alaskans if caught in fresh water streams.
A while ago I posted a video of the IguazĂș Falls (Argentina Brazil Paraguay) but I never saw it again on this thread. Was it rremoved
The post of the video is still there, @Silvia Benoit ; but the thread has gone on a couple pages since then, is why you are not seeing it on this page. The video is on page #8 of this thread and we are now on page #10. Here is the link to the page that it is on in this thread: http://www.seniorsonly.club/threads/amazing-amusing-videos.9988/page-8
