For the cottage I'm liking the idea of putting back in water - will try that when I've my next week on Kashagawigamog. That is - if I catch anything. I'll dump somewhere where I can watch the carcass and how long takes to disappear . . .
As for burying - agree with others that not recommended if good scent dog or hound in yard - bored, they'd find in no time unless deeply covered.
For my holes I usually dig down 2' then add the mostly frozen fish (wrapped in newspaper) then cap with 6" compressed earth.
A year or two later when digging through same area is amazing to see the numerous amounts of big worms.
I've never had problems with skunks or racoons digging up. Never odours.
In front yard gardens I can only dig under the stepping stones - everywhere else would disturb the bulbs . . .
