Not exactly on subject but I have witnessed bass herding minnows. I was standing on a large rock that was part way into the water. The rock had a depression that formed a small puddle that connected to the lake by a small channel. The puddle was maybe 3 feet across. The channel was maybe a foot wide with water only an inch deep. I saw several bass that were chasing a school of minnows. The minnows were using the channel as an escape route to get into the puddle where the bass could not follow. The bass would take up position surrounding the channel entrance and just wait for the minnows to leave the puddle. As groups of minnows headed into open water the bass pursued and gobbled up as many as they could catch. Some of the minnows retreated back into the puddle. The ones that didn't were either eaten or dispersed out into the lake. The bass would herd them back together and drive them back into the channel and the whole thing would start all over again. I watched them do this for an hour. Wished I had my video camera.

Gotta get back to fishin!
