A fishing device includes a net disposed in a body of water containing fishes. A plurality of posts, wherein each post further includes a stem, a bottom cross disposed at a lower portion of the stem; a cross bar disposed at a top end of the stem; and a cord. The stem is an upright elongated protrusion extending from under a bottom to above a surface of the body of water. The cord is slidably secured to the cross bar. A first end of the cord is secured to a weight. A second end of the cord is secured to the net. The fishing device includes a release mechanism. The release mechanism grabs a portion of the cord to hold the weight in a first position adjacent to the cross bar. A bait system is disposed at or adjacent to a center of the net.

In some embodiments, an arrow comprises a shaft and a notch in an end of the arrow. The notch is arranged to receive a bowstring. A first finger recess and a second finger recess are located in proximity to the notch. The first finger recess and the second finger recess comprise opposed diverging surfaces. In some embodiments, an arrow comprises a magnetic slider.

A net assembly used for purse seine fishery, which is mounted on a first vessel, dropped into seawater from the first vessel, and towed by a second vessel to surround and pull fish to capture fish. The net assembly includes a plurality of floats floating on a surface of seawater to provide buoyancy to the net assembly, and coupled to one another in a spaced manner in a lengthwise direction of the net assembly; a net combination of a plurality of nets disposed under the floats in an inter-coupled state, and sunken and deployed from the surface of seawater to surround and capture fish; a weight body extending along a lower end of the net combination to provide a sinking force by means of gravity to sink the net combination; and a purse wire extending along the net combination while being spaced apart from the weight body in a downward direction, and tightened by the first vessel to allow the net assembly to form a closed space below the surface of seawater.

The present invention provides an eco-friendly underwater buoy and a manufacturing method therefor, the underwater buoy comprising: a liner main body of which the inside is hollow; a winding member which is melt welded on the outer surface of the liner main body by winding, and which absorbs external shock; and buoy couplers embedded in both ends of the liner main body so as to couple adjacent underwater buoys to each other. The present invention winds, through filament winding, a wire, in which a glass fiber, a resin and the like are mixed, around the outside of a liner structure so as to manufacture an underwater buoy, and thus, since the underwater buoy is made of a composite material, the appearance of the buoy structure can be stably maintained for a long time without damage caused by various underwater shocks, so that underwater environmental pollution caused by buoy structure damage can be minimized, thereby maximizing the eco-friendliness of the underwater buoy.

A curtain of a boom for harvesting brine shrimp eggs includes mesh sections for directing a flow of water in a first direction such that an amount of the brine shrimp eggs swept under the curtain of the boom during a harvesting process is minimized and a bottom section located below the mesh sections for directing a flow of water in a second direction during the harvesting process such that debris in the water is swept under the curtain of the boom.
