A farming system for use in water-based farming of a product includes a structural frame arranged to define a farming cell. The structural frame includes a first edge member, a second edge member vertically offset from the first edge member, a third edge member extending between the first edge member and the second edge member, and a fourth edge member offset from the third edge member and extending between the first edge member and the second edge member. The first edge member, the second edge member, the third edge member, and the fourth edge member, cooperate to define a first wall perimeter. The farming system also includes a plurality of cable assemblies coupled to the first edge member. Each cable assembly includes a cable having a first end and a second end with the second end fixedly attached to the second edge member. A cable tensioner is coupled to the first edge member and the first end of the cable, and a sensor is coupled to the cable and operable to measure a tension level of the cable. The farming system also includes a controller operable to receive a signal indicative of the tension level of each cable from each sensor and to operate each of the cable tensioners in response to the associated tension level to maintain the tension level of each associated cable within a desired range.

A net monitoring system, including: a plurality of net monitoring devices, each net monitoring device including: a housing; a plurality of tensioning arms, each tensioning arm reversibly extendable through the housing and configured to reversibly secure to a net, each tensioning arm including a force sensor configured to generate a tension signal indicative of a tension applied to the corresponding tensioning arm; a tensioning mechanism configured concurrently retract the plurality of tensioning arms into the housing; an impulse generating device, configured to generate an impulse responsive to a command; and a communications device configured to receive the tension signals from the plurality of force sensors, and transmit the tension signals through water; and a controller, configured to: command at least one of the plurality of net monitoring devices to generate the impulse; receive the tension signals responsive to the command to generate the impulse; and determine, based on the received tension signals, a presence of a defect in a net on which the plurality of net monitoring devices are installed.

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.

Methods are provided for forming spliced connections in coverbraided ropes in the form of a sling having at least one eye. The methods include the step of situating a void spacer adjacent to a portion of a core rope. The methods also include coverbraiding the removable void spacer to create a tunnel into which a section of the same coverbraided sheath enclosing a strength member core is able to be positioned in between the strength member core and the coverbraided sheath enclosing the strength member core in the vicinity of the spliced eye's splice braid zone, thereby forming a spliced eye connection.

The present invention is a highly-efficient, self-propelled apparatus for cleaning nets used for farming of fish and other organisms while the nets are submerged.

In various embodiments, the invention includes two rotating washer head assemblies, with spray bars and corresponding deflector plates. A high-pressure water stream is discharged from the spray bars at an angle that creates a torque force to actuate and maintain rotational movement of the washer head assemblies. The subsequent deflection of the high-pressure water stream by the deflector plates creates a thrusting force to propel the self-propelled apparatus toward the nets.
