A retrieval system and methods of preparing and using same to retrieve underwater objects from a selected depth, including a flotation device having at least a selected amount of buoyancy, a release mechanism that is capable of releasably engaging an anchor, and a controller to actuate the release mechanism when a selected condition is achieved. The system further includes a spool assembly having a frame for carrying (i) the floatation device, (ii) the release mechanism, (iii) the controller and (iv) in combination with the flotation device, a quantity of pre-wound line having a length greater than the selected depth.

The fishing device comprises a first and second side panel connected at a pivot joint, having end panels and a closing system connected thereto. The first and second side panels are preferably curved or rectangular such that an interior void can be formed when the side panels are pivoted together. End panels connect to side panel in order to block access to the interior void from the front and back of device when the side panels meet together. At least two hatch openings are attached to the first and second side panel. Closing system acts to close the catching device, when the device is at the bottom of a body of 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.

An extendable pot for catching fish includes a frame structure comprising a main frame structure and an extendable frame structure, with the extendable frame structure comprising a number of floating elements extending the extendable frame structure out from the main frame structure when the pot is immersed in water.
