A fishing system includes a submersible fishing implement for being received in a body of water and configured for capturing one or more fish. An implement driver is configured to drive movement of the submersible fishing implement through the body of water. A data collection system includes one or more sensors for sensing one or more fishing parameters and transmitting a fishing parameter signal representative of the one or more fishing parameters. A controller is operatively connected to the data collection system to receive the fishing parameter signal and to determine based on the fishing parameter signal a selected fishing location. The controller is further configured to transmit a navigation signal to the implement driver operative to control the implement driver to drive movement of the submersible fishing implement toward the selected fishing location.

Embodiments of the present invention relate to methods and apparatus for sorting undesired marine species during trawling, provides a pliable grid when the trawl net is pulled from the water and wound tightly on the net reel, and when the trawl is deployed in the water, the apparatus is fixed into place inside the trawl and holding its shape with consistent grid spacing. Marine species sorting apparatus in accordance with embodiments of the present invention includes grid, back straps, and lead ring. Grid includes a plurality of bars surrounded by grid frame. Grid frame is attached to lead ring at an angle using terminal couplers. Lead ring supports grid and secures marine species sorting apparatus in trawl webbing referred to as the extension.

A method for extracting aquatic animals from an apparatus (102) containing aquatic animals. The apparatus has a body with an open end (102a), a substantially closed end (102b), and one or more side walls (102c) between the open end and the substantially closed end. At least a major portion of the side wall(s) are in the form of a flexible membrane, and at least a major portion of the side wall(s) and the substantially closed end are substantially impervious to water. The method involves arranging the apparatus (102) with an open end (102a) of the apparatus positioned higher than a substantially closed end (102b) of the apparatus, introducing a flow of liquid into an interior region of the apparatus proximal the substantially closed end, and using the introduced flow of liquid to transport aquatic animals contained in the apparatus, out of the open end (102a) of the apparatus.

A continuous trawl fishing method includes: by dragging a fishing net in water through a vessel, carrying out trawling operation so that catches to be fished enter a cod-end of a fishing net tail; then tractioning and moving the cod-end so that a sucking fish tube of a vacuum sucking fish pump reaches into the cod-end; and a tube mouth of the sucking fish tube contacting the catches in the cod-end to run the vacuum sucking fish pump to suck the catches from the cod-end into the collection tank through the sucking fish tube, and the catches in the collection tank being then transferred and frozen or directly processed. The fished catches of the present invention are obviously improved in indicators such as the stiffness time and the number of the first-grade fresh fish and so on. The histamine content is obviously reduced and the catch quality is improved.

A multipurpose portable or transportable selective fish capture system and no touch transport system is described that comprises an interconverting pontoon platform which can be adapted to include a solar and/or hydro electrical energy collection, conversion, storage and distribution system and to convert between a selective fish capture system and no touch fish transport system and an for emergency response for search and rescue or oil spill response support and oil spill collection and oil transport system.

A lace line for forming structures including netting, such as codends, trawl nets, seines and fish pens, The lace line includes at least several distinct loop tails that are interlaced and/or interconnected with one another so as to form several lacing loops, In other aspects, the present disclosure teaches a codend including at least four hung-in riblines having at least four netting panels formed mainly and preferably entirely of T90 mesh, where the T90 mesh mainly and preferably entirely includes a mesh size of between one hundred sixty and one hundred ninety five millimeters, in combination with a hang percentage of between ten and twenty four percent.
