Drop to 7 or 8. No need to cut the limit in half. 20-30% decrease will be fine with me. Fewer fish kept will = bigger fish kept. 5 - 15" trout won't make for a very big fish fry for a family of 3+.
Whay decrease the limit at all? Is there a shortage of trout? I think not. Is just keep five just personal opinion backed up by studied info or just because you may not eat as much fish as the next guy? Or maybe you fish more and dont need to keep ten?
I think lower limits would allow for more fish to be hatched thus increasing the potential for bigger fish. The 25" plus fish are not laying as many eggs as the smaller ones.
I fish for fun and usually don't keep any fish. Might be a holdover from my bass fishing days.
