  • Patent number: 4642934
    Abstract: A transportable liner for use in a live well is disclosed, for transporting the catch, such as fish from the live well. The liner is substantially made of a flexible, porous material forming a plurality of adjoining sides and bottom which form an open topped porous enclosure therebetween. A draw string is disposed along the upper portion of the adjoining sides, in a manner to draw the sides together when the draw string is pulled, to enclose the catch within the liner. Releasable retaining apparatus, such as suction cups, hook and eye fasteners or magnets are used to releasably secure the liner to the live well. Weights, or weighted cord, may be secured to the liner in proximity to the bottom of the liner to resist bouyancy of the liner within the live well, when in the presence of an aqueous fluid.
