Abstract: The present invention is directed to a method and a system for the production of at least one polymeric yarn comprising means for mixing a polymer (1) with a first solvent yielding a mixture; means for homogenizing the mixture; means for rendering the mixture inert (21, 22, 23); means for dipping the mixture into a quenching bath (30), wherein an air gap is maintained before the mixture reaches the quenching bath (30) liquid surface forming at least one polymeric yarn; means for drawing (41) the at least one polymeric yarn at least once; means for washing (5) the at least one polymeric yarn with a second solvent that is more volatile than the first solvent; means for heating the at least one polymeric yarn (6); means for drawing at room temperature (7) the at least one polymeric yarn at least once; and means for heat drawing (8) the at least one polymeric yarn at least once.

Abstract: A system includes a housing; a water tank positioned within the housing, wherein an inside of the water tank is sealed to prevent contact between material forming the water tank and water within the water tank; a water movement subsystem causing water to circulate within the water tank, including a baffle extending along the center of the water tank dividing the water tank into a circular raceway, and a pump causing water to circulate; an aeration subsystem maintaining an oxygenation level suitable for crustaceans to live within the water tank; a temperature control subsystem maintaining a water temperature suitable for crustaceans to live within the water tank; a water quality monitoring subsystem monitoring a water quality parameter of water within the water tank; a feeding subsystem configured to dispense food into the water tank; a biofloc removal subsystem configured to remove biofloc from the water tank; and a control system.
