We learn how to throw a cast net. There are many different ways to do this since everyone develops their own personal technique. The way we're shown is this way: First choose your bait. Then get all the rope up in your hand. Lay your hand on the top. Come down about halfway. Lay it back on top again, Hold net up. Grab the lead line. Although many people dislike doing it this way we see him put it in his mouth. Then he grabs the led line and throws it, releasing the lead line at the right moment.
