"Short Talk on Trout."
"In haiku, there are various sorts
of expressions about trout.
Autumn trout and descending trout and rusty trout
are some I have heard.
Descending trout and rusty trout are
trout that have laid their eggs, worn out, completely exhausted.
They are going down to the sea.
Of course, there were occasionally
trout that spent the winter in deep pools.
These were called remaining trout."
