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.

A decorative article of manufacture has a specific region of fishing net, cut from a larger expanse of fishing net, the fishing net being a structure of a first plurality of first parallel lengths of cord proceeding in a first direction, overlying a plurality of second parallel lengths of cord proceeding in a second direction, with individual ones of the cords of the first plurality joined at intersections with individual ones of cords of the second plurality, forming individual quadrilateral cells each having opposite parallel sides, and one or more solid decorative elements attached to one or more sides of individual ones of the quadrilateral cells.

The invention relates to a wire material consisting of metallic material having an oxide surface, wherein the oxide surface of the wire material has a first oxide layer, which covers the metallic material at least in part and has a thickness of at least 200 nm to 2 μm, and the oxide surface of the wire material has a second oxide layer which covers metallic material in the regions which are not covered by the first oxide layer. According to the invention, the second oxide layer has a maximum thickness of 0.01 to 10% of the thickness of the first oxide layer. The invention furthermore relates to a mesh and a breeding cage for aquaculture.

A system to monitor compliance with fishery management regulations by recording time and location stamped video of a catch. The system utilizes battery powered miniature camera/DVR modules capable of being mounted virtually anywhere on a fishing vessel. The cameras are activated by software triggers using motion and changes in hydraulic pressure to avoid the capture of unwanted video and unnecessarily draining the battery. A method of analyzing the video data to ascertain species, size, and mass is also disclosed.
