Abstract: System for transporting a liquid from a reservoir containing the liquid. The system includes a first and second conduit, each with a lower end and an upper end, a first pump, with an inlet end and an outlet end; wherein one of the lower end of the first conduit or the upper end of the second conduit is connected to a second pump; wherein a height difference between the first and second pump is within a maximum pumping height of a lower pump of the first and second pump. Further, the present invention relates to a method for operating a plurality of pumps in a system.

Abstract: A crowding arrangement for an aquaculture tank of marine organism where the tank includes at least one outlet in a bottom of the tank. The crowding arrangement has a sheet extending between a hub and an outer ring. The sheet encircles the hub at the center of the tank. The sheet, hub, and outer ring cover a horizontal cross-sectional area of the tank. The crowding arrangement also has a first wiper assembly and either a second wiper assembly or a fixed wall extending substantially radially between the hub and the outer ring. The first wiper assembly is movably arranged with respect to the sheet and includes a crossbar and a wiper fixedly attached to one another and which are arranged in parallel to form a gap therebetween to receive the sheet and small enough to prevent marine organisms to pass through the gap.

Abstract: A water and seafood flow distributor (1) for routing flowable mass from a first location to a selected one of a second plurality of locations. The distributor (1) has a first pipe (5) and a second bent pipe (51), which are in communication with one another at a first end (8, 8?) via a mass mover. The second bent pipe (5?) is rotatable about the first end (81) to displace a second end (91) along a circle (121). A first conduit (10) is in communication with the first location, and a plurality of second conduits (10?) are in communication with a respective one of the second plurality of locations, and the ends of the conduits are arranged along a circle (12?) described by the second end (91) of the second bent pipe (51). The first and second conduits can be fluidly connected through the first and second pipes.

Abstract: The present invention relates to a system (100) for transporting a liquid from a reservoir (600) containing the liquid. The system comprises •a first and second conduit (400, 500), each with a lower end (402, 502) and an upper end (404, 504), •a first pump (200), with an inlet end (201) and an outlet end (202): •wherein one of the lower end (402) of the first conduit (400) or the upper end (504) of the second conduit (500) is connected to a second pump (300): —wherein a height difference between the first and second pump (200, 300) is within a maximum pumping height of a lower pump of the first and second pump (200, 300). Further, the present invention relates to a method for operating a plurality of pumps in a system (100).

Abstract: A method of moving farmed aquatic animals from a tank containing the animals, the tank having a tank outlet and a conveyance pipe, the conveyance pipe having a conveyance pipe inlet connected to the tank outlet and a conveyance pipe outlet at an outlet elevation higher than the tank outlet, the method comprising: (i) by means of a water inflow into the tank, maintaining a water level in the tank at a level above the outlet elevation to generate a flow of water from the tank through the conveyance pipe while positioning a moveable water-permeable screen inside the tank to crowd the animals towards the tank outlet, (ii) by means of the flow of water therethrough, moving animals through the conveyance pipe.
