Chuck, some likely new tilapia records have been caught on Squaw Creek in Glen Rose. I can't recall what is listed now as the record but I am supposing many by now have been caught that greatly exceed the existing record, just not any interest in claiming a record.
One I caught last year while LMB fishing from the banks was a little over 16" so I slid him along my size 13 boot for a pic. Then, I caught one even longer, 18" or so as I recall, and a bigger girth a few months ago. Second pic and it likely weighed close to 3 lbs.
Finally, two friends were out with Dannie Golden, a well known guide in N. Texas, and they caught two tilapia in the 3.5 to 4 pound range on the same lake while bass fishing.
There is a no-throw back rule on Squaw Creek. The hot water lake really grows monsters.
If you get in the mood for a tilapia fest, some of the guys get way back up in the Squaw creeks during the summer and pull them in, big ones too, by the dozens.
Hey! A nice record for the waters you are fishing!
