A lure for use in angling for predatory fish has a hollow body shell having a generally fish-shaped form, provided with one or more fish hooks. A frontally-located funnel provided with a debris filter allows water to pass into an interior of the body shell. The water passes through the body shell and flows out through a rear discharge aperture and a lateral orifice which may include an intermittently-opening valve. A forwardly-projecting tongue in some versions acts as a diving vane. Other versions include a dorsal air intake connected to an entrainment tube to inject bubbles into the outflow of water, devices to generate vibrations or sound, or to attract fish, and versions optimised to dive and rise controllably, remain adjacent the surface, or sink then remain at depth.
