The first count showed only 20 adult frogs and 20 tadpoles. In September, the field crew counted 120 adults and 1,300 tadpoles. Similar results are being recorded in three other field tests. Removing the fish turns out to be a very effective method of frog recovery. Just a few lakes would help, Knapp said, leaving plenty of fish around.
Some anglers are suspicious.
What I am saying is the fish have a place also. Officials at the California Fish and Game Department insist that nobody plans to eliminate fish. Instead, the issue is whether stocking needs to continue as it has outside the national parks, and whether fish may need to be taken out of some critical frog habitats. Researchers are now looking at how an effective amphibian rescue might be attempted by selectively returning certain lakes to their original, fish-free state. Right now we're trying to figure out just what the frog needs.
