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.
Claims20
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 from 110 grams/meter squared to 350 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.

- and
- a second support wire coupled to the helical spring at the second end wall, the second support wire extending along the helical spring for less than half the circumference of the column.
