You can also train the Tilapia by hand feeding them with a handfull of feed thrown in every few minutes about 5 times in a row for a week or so....gradually reduce what you feed each time to just a few pellets every minute for 10-20 minutes.
After you see the Tilapia swarming when you get close to the water toss in a couple pellets and a hook with a Stubby Steve or other bait and catch away.
