A harvesting device particularly suited for harvesting artemia cysts. The invention in its various embodiments comprises a frame and a net coupled to the frame. The frame can include a front support frame, a rear support frame and a sledding frame. A net having a first end and a second end can be secured to the front and rear support frames respectively. In certain embodiments, the net has an aspect ratio or 4:1. One or more skids can be coupled to the frame. In certain embodiments, the skids are coupled to the sledding frame. In yet other embodiments, the skids are coupled to the sledding frame at substantially the joining of the front support frame and the sledding frame. The second end of the net can be attached to a conduit in communication with a harvest vessel by a coupling. The harvest vessel can include one or more dewatering stations in communication with the conduit.

The invention discloses a deep sea fishing cage comprising supporting frameworks and cage nets arranged therebetween; said supporting framework comprises a float supporting component and cage frameworks symmetrically arranged on two sides of float supporting component; said cage frameworks are connected with float supporting component via cage nets; the float supporting component comprises a float support rod and a support frame counterweight steel bar; said float support rod is arranged above support frame counterweight steel bar and funnel-shaped escape-proof plate is arranged on lower side of float support rod; said cage framework comprises a supporting component and a cage sealing component, wherein said supporting component is connected with cage sealing component via net surface, said supporting component comprises an upper supporting frame and a lower supporting frame, and two ends of said upper supporting frame are connected with two ends of lower supporting frame respectively to form a semicircular structure.

The present invention is a hoop net comprised of netting mounted to two semicircular tubular rods, forming a ring that maintains its shape and structural integrity. The two semicircular tubular rods are fashioned to connect seamlessly by a fastening means that allows the entire assembly to function as intended. The hoop net assembly includes four stabilizing cords positioned equidistant from each other along the ring, which cords converge at the center of the hoop net assembly and are connected to each other by a fastening means, then further connected to a single draw cord. The draw cord is used to cast the assembled hoop net into water to a desired depth and pulled back into the boat with live bait. Once the hoop net assembly has been used, the metal rods are easily disconnected to facilitate folding the hoop net in half for easy storage and portability.

An intercepting net based on reversing current motion at a river bottom, including a net body connected to ropes arranged in a crisscross manner, an anti-floating and anti-drifting rope and a mounting frame. A top of the net body is connected to a main rope and an auxiliary rope arranged side by side. The anti-floating and anti-drifting rope includes lead-core ropes arranged in a crisscross manner and connected to the ropes. The net body includes a vertical interception portion, whose bottom is connected to a first anti-escape net portion extending in a first direction and a second anti-escape net portion extending in a second direction opposite to the first direction. First anti-floating and anti-drifting chains are sequentially fixed on the first anti-escape net portion along the first direction. Second anti-floating and anti-drifting chains are sequentially fixed on the second anti-escape net portion along the second direction.
