A portable basket is used to collect multiple weighted lines that extend between a buoy and a submerged crab pot. The basket is a cylindrical structure with flexible sidewalls that extend from a top edge to a bottom panel. Attached to the inside surface of the basket near the top edge are at least two ring connectors. During use, the basket is positioned below a winch system to pull the weighted line and the crab pot out of the water. The weighted line's first connector is detached from the buoy and connected to a ring connector inside the basket. The winch is then activated to allow the weighted line to fall into the basket and get automatically stacked in a vertical coil configuration inside the basket. When the crab pot is lifted out of the water, the second connector is detached from the crab pot and attached to the second ring connector near the top edge. The process may be repeated to collect additional weighted lines. When setting a crab pot, the buoy and pot connectors from one weighted line are detached from the ring connector and attached to desired buoy and pot, respectively. The buoy, the pot, and the coiled weighted line can then be deposited into the water.

Various aspects of the disclosure generally relate a fish trap for use in waters among marine predators which use echolocation. In one aspect the fish trap has acoustic masking properties. In one aspect the fish trap may be a lightweight, collapsible column for use by small commercial vessels and recreational fishing. In one aspect the fish trap may have an overlapping net, forming a double seam for added strength. In one aspect the fish trap may have reinforcing wire along bridle attachment points to hold heavier loads of fish.

Tubular bait fish retrieval apparatuses comprise a generally cylindrically-shaped or prism-shaped body comprising an opening on a first end thereof configured to allow passage of a bait fish therethrough, and a generally closed second end having at least one aperture configured to fill the body with water when disposed within the water and for draining the water from the body when removed from the water. Methods of using the same are further provided.

Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

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.
