Great question! Berkeley Powerbait Trout Worms are indeed designed with some buoyant properties. This buoyancy helps keep the worm off the bottom, making it more visible and enticing to trout. When rigged correctly, such as on a jig head or under a float, the worm will have a natural, lifelike presentation in the water.
From the video context provided by Nathan Quince Fishing, we can see that these worms are often used with a float or jig head to keep them suspended in the water column, which suggests that their buoyant nature is beneficial for this type of fishing. Nathan mentions using a float to keep the bait above the fish and giving it little jigs to mimic natural movement, which is easier to achieve with a buoyant bait.
If you're fishing in a creek or lake, the buoyancy of the Powerbait Trout Worms allows them to stay in the strike zone longer, increasing your chances of catching trout. They can be particularly effective when there's some wind, as the float will move with the waves, causing the worm to jig up and down naturally.
If you have any more specific questions about rigging or techniques, feel free to ask! Happy fishing!
