Organism eradication system and method of use

An organism eradication system for in situ capture and treatment of target organisms within a body of water, the system comprising:

• a concentrator having a concentrator inlet formed by a blocking net having a first mesh size and having a downstream concentrator outlet fed by a pass-through net interconnected with the blocking net, the pass-through net having a second mesh size, wherein the first mesh size is larger than the second mesh size;
• a holder having a body formed to selectively allow passage of sunlight, the holder defining a transient volume within which a fluid sample containing the target organisms as obtained by the concentrator may temporarily dwell, the holder comprising a holder inlet defining an expansion chute having an expanding cross-sectional area for slowing and widening the flow of the fluid sample entering the holder;
• at least one tether interconnecting the concentrator and the holder and at least one ballast operably engaged with the concentrator and the holder via the at least one tether so as to provide for stability and positionability between the concentrator and the holder, the blocking net forming the concentrator inlet engaged with the at least one tether for further stability and positionability thereof;
• a connector tube in fluid communication between the concentrator outlet and the holder inlet;
• a mixing section along and in fluid communication with the connector tube, the mixing section comprising an injector for selectively injecting an agent into the fluid sample, the agent selected as being lethal to the target organisms;
• and
• at least one pump operably installed in fluid communication with the connector tube for moving the fluid sample through the system, a closed-loop control system comprising the at least one pump serving to control flow rate of the fluid sample and to stabilize velocity through the holder in cooperation with the expansion chute;
• whereby placement and positioning of the concentrator within the body of water via the at least one tether and the at least one ballast and capture therein of the target organisms within a size range between the first mesh size and the second mesh size so as to pass the captured target organisms to the holder via the connector tube and the mixing section results in exposure of the target organisms to the agent and dwell of the target organisms with the agent under localized environmental stress within the holder for improved lethality of the agent.
