There's a few surprises on the list of fish saved during ``pre rotenone application salvage,'' prior to the fish kill on the Sanitary and Ship Canal. And a surprise missing species too.

``Those fish were transported outside the treatment area,'' e-mailed IDNR spokesman Chris McCloud.

Here's a more specific list of fish saved.Species saved and number:
largemouth bass 63
smallmouth bass 1
bluegill 83
channel catfish 10
grass pickerel 2
black crappie 1
walleye 1
goldfish 1
sunfish 90
The surprises, at least to me, are grass pickerel and the lack of any northern pike.
USFWS report (pdf) on Chicago waterways has data on previous fishery surveys. Table 43 (1991) & Table 21 (1976), Reach 9B.
More species and the relative numbers show increases in Bluegill, Sunfish and Bigmouth while Goldfish numbers collapsed.
Bluegill in Japan. Familiar tale.
