I have noticed that double and treble hooks are common place fishing for atlantics, especially on tube flies. Often times the trebles are very small. Many of the people using them are conservation minded and practice strict catch and release. I personally have never fished for atlantics but from what I have heard they are in need of ethical catch and release every bit as much as our steelhead. I have always heard that trebles increase fish mortality and make a stress free release more difficult. They aren't really used on flies out here but are common with guys throwing spoons and spinners. My only experience with treble hooks was fishing eggs and throwing panther martins for trout as a kid. When they swallowed the hook with eggs that was the worst but I dont really remember trout swallowing a spinner. So my question is... why are they using trebles?? Does it increase their landing ratio or is it that they really don't see a correlation between the hooks and fish mortality?? Or is it a tradition/culture type thing? These are just questions I have I'm not saying they shouldn't be used or anything like that.
