ANGLERS
INVITED TO HELP WITH ROUND GOBY ROUNDUP - '99
The
USFWS is inviting everyone to get out their gear and join in on a fishing
trip June 8-10 in the Chicago Waterways - Round Goby Roundup '99. Not only
will the trip allow people to enjoy the fun of fishing, but it may help
locate the leading edge of distribution for the aquatic nuisance species
the round goby information which could help slow the spread of this potentially
harmful fish.
Participants
must provide their own boat, fishing gear, and bait. Small worms on #12
or 14 hooks fished on the bottom are recommended. Anglers will be asked
to provide information on the amount of time fished, and whether they catch
round goby, and if so, the capture location. If anglers catch a round goby,
they should kill it, place it in a plastic bag and contact Pam Thiel at
the Baymount Hotel at the corner of 127th Street and Cicero Avenue, (708)597-3900.
The
round goby has known populations in all of the Great Lakes, and has made
its way into the Illinois Waterway, a series of man-made canals and natural
rivers connecting the Illinois and Mississippi Rivers to the Great Lakes.
The round goby, a bottom-feeding species, is known for its aggressive feeding
and defensive behavior. The goby is a soft-bodied fish, identified by its
fused pelvic fins. Despite its small size, most commonly ranging from 3-to
6-inches in length but capable of growing to 10 inches, its rapid reproduction
and aggressive feeding behavior threaten populations of native fish. It
has received national attention since increasing populations could seriously
impact the sportfishing industries on the Great Lakes and Mississippi River
basin, as well as upset the natural balance of the ecosystem.
To
date, round goby have been collected about 15 miles inland from Calumet
Harbor on the Calumet River and in the turning basin inside the lock on
the Chicago River. Locations that anglers are requested to monitor are
on the Calumet-Sag Channel and Chicago Ship and Sanitary Canal downstream
from the Alsip municipal boat landing and the Chicago River downstream
from the lock and the Chicago Ship and Sanitary Canal. --See map below--
