摘要： An improvement in cast nets includes a first ring to which a throw rope is releasably attached and a second ring that is interconnected to the first ring by a housing that allows the rings to swivel independently with respect to one another. The second ring is releasably attached to a semicircular handle that is attached to an apertured flat disc. Each brail has an uppermost end that extends through an aperture in the disc and which is knotted so that it cannot fall back through the aperture. An annular ring is releasably attached to the flat disc and overlies the knots to prevent axial travel of the brails. The rotational connection between the rings facilitates throwing the net, and the connection of the top end of the brails to the apertured disc inhibits tangling of the brails with one another and facilitates replacement of broken brails.

摘要： A non-collapsible fish net apparatus (31) with capturing method, comprising an endless net (33) mounted on spaced rigid hoops (37, 38) preventing collapse, a skirt (39) below the lower hoop (38) foldable on itself, apparatus support lines (45) mounted to the upper hoop (37), control lines (51) folding and unfolding the skirt (39), a draw line (62) about the skirt (39), a closure weight (57) attached to the draw line (62), and a line (58) for dropping the weight (57) farther down to close off the skirt (39). Buoys (55) on the control lines (51) provide a signal for actuating the weight (57). Corks (44) on the upper hoop (37) float apparatus (31). A wave netting (70) at the upper hoop (37) prevents fish escape in a wave cascade over apparatus (31). A quick-disconnect assembly (65) on the draw line (62) distal to the closure weight (57) opens the skirt (39) in event of apparatus overload. Apparatus (31) encompasses fish in water after which the draw line (62) is tightened by release of the weight (57), thus, capturing them.

摘要： A snatch block has its sheave established by connecting the smaller ends of a pair of frusto-conical shell portions to a central member rotatably mounted on an axle protruding from one side of the hanger. The larger ends of the portions merge with end walls which are normal to the axis of the sheave and extend outwardly a distance greater than line diameters. The end walls have lips which are disposed relative to fixed water shields in a manner preventing a line, running against an end wall, from contacting the proximate water shield.

摘要： An improved, high catch yield pull-behind net assembly particularly designed for shrimping and fishing operations in shallow coastal grass flats is provided which actually causes aquatic life to move upwardly into the net, is completely harmless to the ecology of the grass flats, and can be unloaded on the go without interrupting the fishing and shrimping. In preferred forms, the net assembly includes an upright, inclined, elongated mouth, a trailing net secured to the mouth, and a vibratory, multiple-bar elongated roller mechanism located adjacent the underside of the net mouth for supporting the overall assembly; the roller mechanism repeatedly strikes the bottom in advance of the net mouth, causing bottom-congregating aquatic life (e.g., shrimp and flounder) to move upwardly and pass into and through the net. The net mouth is also provided with a plurality of spaced, depending, spring steel rods which effectively "comb" the grass as the net is advanced to ensure maximum catches.
