Render a detailed 3D model of the AquaCatch fishing system. The model should include a ball-shaped closing net made of durable polyester with internal hooks, connected to a telescopic aluminum pole. The pole is attached to a boat where a steel air capsule is located. Polyethylene pipes run from the capsule to four inflatable nylon air bags on the net. A digital weight sensor at the top of the pole triggers the net to close when a certain weight is reached, causing the air bags to inflate and bring the net to the water surface.
