Abstract
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.

A fish trap comprising:
- a spring with a thickness greater than or equal to 6 mm, configured to have an expanded state, the spring in the expanded state having a width greater than 50 cm and a length greater than 100 cm;
- a net coupled to the spring forming a side wall, first end wall and a second end wall at the two opposite ends of the spring, lengthwise, each of the first end wall and the second end wall having a web, the spring having an interior defined by the bounds of the net and the web at each of the first and second end walls, the net having a surface density at least 110 grams/meter squared;
- and
- a first hoop in the first end wall coupled to the web in the first end wall and creating a first entrance, the first hoop having a width less than the width of the spring, the first hoop configured to allow fish to access the interior of the fish trap.

A fish trap comprising:
- a helical spring with a thickness greater than or equal to 6 mm, configured to have an expanded state, the spring in the expanded state having the approximate shape of a column with a diameter greater than 50 cm and a length greater than 100 cm;
- a net coupled to the spring forming a side wall for the approximately shaped column, a first end wall and a second end wall at the two opposite ends of the helical spring, lengthwise, each of the first end wall and the second end wall having a web, the helical spring having an interior defined by the bounds of the net and the web at each of the first and second end walls, the net having a surface density at least 110 grams/meter squared;
- and
- a first hoop in the first end wall coupled to the web in the first end wall and creating a first entrance, the first hoop having a diameter less than the diameter of the column, the first hoop configured to allow fish to access the interior of the fish trap.
