No tilapia in these lakes.. it will be very interesting to see what happens. I noticed the 'average' size catch of the fish as well. Think the smaller ones are doing what they should do, and getting eaten?
Roosevelt has been a great largemouth lake, and decent smb. Tshad have been key forage for a long time. 18 inch shad aren't so helpful as forage themselves.. but it will be interesting to see if the larger forage available moves the LMB up in weight. Over 20,000 surface acres, so we're never going back in time...
Amazing at Lake Powell in just a few year this happened: "Biologists at Lake Powell first noted gizzard shad in 2000 near the San Juan inflow. In netting surveys at Powell in 2006, gizzard shad accounted for almost as much fish flesh as striped bass." Yikes.
