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.

A fishing device particularly designed for Asian carp fishing, which includes two fishing boats, a collection frame, a fishing net, a display mechanism with a plurality of optical sensors and optical receivers, one support mechanism for one fishing boat and one lifting mechanism for one fishing boat. The lifting mechanism includes a motor, a rotary shaft, a bait holding basket, a plurality of shaft supports and a plurality of rope units. Thus, a selected bait can be used for classification fishing. The quantity of fish catch can be determined timely through the display mechanism. The lifting mechanism allows steading lifting of the fish catch out of the water without introducing any harm to the fish catch. The number and survival rate of the fish catch can be ensured while an effective fishing can be achieved. This fishing device is particularly designed for catching Asian carp fishes.

A method and system for efficient and eco-friendly shrimp skimmer trawling by a trawling vessel with a trawl net, skimmer booms, net arms, and buoyantly adjustable rollers to maintain trawl net height and net opening without damage to the ocean floor allowing for systematic and frequent retrieval of catch while continuing trawling operations in intervals short enough to prevent death of by-catch and endangered species and where the system is fully storable on trailerable trawling vessels for maintenance of allowable highway heights. The system and method has the upper edge of the trawl net held above the ocean surface while the trawling vessel moves forward.
