An embodiment can include a vessel-towed system that includes a first towing/communication interface system, e.g., a first tow cable with a fiber optic system, and spaced apart buoys for supporting the first tow cable. A first mobile structure including a first control system and first type of emitter, e.g., an attraction system, is connected to the first tow cable. A second mobile structure is provided that can include an underwater towed emitter such as an audio emulation system. The first and second emitters can be configured emit a first and second plurality of emissions for inducing a receiving entity response. The second mobile structure is coupled with the first mobile structure with a second tow cable that comprises another fiber optic cable. An automated response or manual control systems can be provided on the towing vessel and the first mobile structure adapted to operate the first and second emitters.

A target stand has a generally level bottom surface having at least one protrusion or cavity sized and shaped to leave an impression in an impressionable surface and a top surface having a plurality of wells configured to receive target supports. The plurality of wells may be configured to receive wooden stakes. The one or more protrusions or cavities may be shaped like animals or animal feet, such as pig's feet. The one or more protrusions may be sized and shaped to leave impressions of letters in the impressionable surface.
