## Title
System and method for attracting crustaceans and other aquatic life

## Abstract

An improved lure for attracting aquatic life, specifically crabs, that utilizes interchangeable sound cartridges. The improved lure utilizes a fully submersible portable unit that hoses all sound production components, including a speaker, and a power source. The improved lure may be configured for activation in low-light settings and for use in connection with traps.

## Background
BACKGROUND AND SUMMARY OF THE PRESENT INVENTION
While there are several examples of systems for attracting aquatic life in the prior art, many are intended for personal use and require that a lure be tethered to a fishing rod or be communicably coupled to some control apparatus. By contrast, the present invention contemplates a self-contained unit specifically designed for larger scale commercial fishing operations.
Certain embodiments of the present invention are designed to attract crustaceans or fish directly towards a sound source emitting synthetic sounds. Such embodiments comprise a portable unit that may be deployed according to a number of configurations.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION
This description as well as FIGS. 1 and 2 depict embodiments of the present invention as they relate to a lure designed for use in commercial fishing.
In one embodiment of the present invention, the lure comprises a portable unit. The portable unit comprises a main body portion. The main body portion may be substantially cylindrical in shape. The main body portion comprises an interior volume into which sound producing components may be disposed. The sound producing components may include sound cartridge configured to cause simulated sounds designed to attract aquatic life to be played through a speaker that is operably coupled to the sound cartridge. The sound cartridge comprises an integrated circuit board or chip. The integrated circuit board may include a microcontroller and memory for storing the simulated sounds. The sound cartridge is further coupled to a power source also disposed within the main body portion.
In further embodiments, the internal, integrated circuit board is a Bluetooth low energy (BLE) board. A light-emitting diode (LED) light sensor may be coupled to the portable unit's internal circuitry. The LED light sensor may be configured to cause a change in the portable unit's power state (on/off) based on the presence or absence of light.
In some embodiments, the portable unit further comprises a removable cap. The removable cap is configured for reversible engagement with the main body portion. In such embodiments, the speaker is internal to the portable unit when the removable cap is engaged with the main body portion. When the removable cap is disengaged from the main body portion, access to the interior volume is granted and the sound cartridge may be removably inserted into the interior volume. Additionally, disengaging the removable cap from the main body portion allows for replacement of the power source. It is envisioned that during typical use of these embodiments of the present invention, a plurality of sound cartridges, each storing a different sound, may be used interchangeably within the portable unit.
In further embodiments, when the removable cap is engaged with the main body portion, a watertight seal is formed to prevent water from entering the interior volume.
In even further embodiments, the speaker may be caused to produce signals that simulate water splashing, the gurgling and moving of waves, and currents or tidal shift against reefs or other geographical features on the ocean floor. The sound cartridge causes the sounds to be played on a loop when the portable unit is powered on.
In certain embodiments, when powered on, the portable unit produces through the speaker low frequency signals, well-known in the art, that emulate a targeted species's acoustical signal that said species emits while feeding. The speaker in this embodiment has an effective attractive radius of 100 meters.
In further embodiments, the portable unit produces low frequency sound pressure, at frequencies well-known in the art, through the speaker and has an effective range of 1,000 meters.
In some embodiments, the power source providing power for the sound producing functionality of the portable unit is two (2) AA LR6 1.5V batteries connected in parallel, and the portable unit has an expected battery life of 400 hours when powered on.
In one embodiment, the main body portion has a length of 111.15 mm, a diameter of 47.68 mm, and a wall thickness of 3 mm. In this embodiment, the main body portion is constructed of ABS 90 (acrylonitrile butadiene styrene). Additionally, the speaker is a 40 mm speaker.
In certain embodiments of the present invention, the portable unit may be configured for placement inside square traps. The portable unit may be attached on the top of a trap or inside bait bags. When these traps are deployed, they may come to rest on the ocean floor or be suspended from a fixed structure. In further embodiments, the portable unit may be deployed independent from a trap.
In one embodiment, the portable unit is adapted for use at depths between 38 meters (125 feet) and 182 meters (600 feet).
In some embodiments, the main body portion further comprises an inner housing bracket for supporting its internal components. In these embodiments, the main body portion further comprises a speaker bracket to support and secure the speaker within the portable unit.
Although the present invention has been explained in relation the various embodiments, it is to be understood that many other possible modifications and variations can be made, and would be understood by those persons of ordinary skill in the art, without departing from the spirit and scope of the invention.
