It starts ... out on the water. Lynn Schlueter is head of the Game and
Fish "walleye spawning" team. "We collect the walleye spawners
with trap nets. These nets do not hurt the fish, just hold them for us.
Milt is extracted from the males, eggs are gathered from the females,
and stirred witth the milt, and in a moment -- fertilization. Then the eggs
are mixed with clay. Without the clay, the eggs will clump together, and
those groups of eggs will often die.
