1. A device for aquaculture, the device comprising:
an aquaculture box configured to store water at a water storing stage when one or more crustaceans are being fed and to drain water and waste material at a water draining stage after feeding, the aquaculture box comprising a box body and a box base, the box body being releasably attached to the box base, the box body comprising an upper end opposite a lower end,
wherein the box body comprises:
a box surface drain hole connected to a box surface drain pipe positioned vertically inside the box body, wherein the box surface drain hole is configured to drain water out of the box body through the box surface drain pipe when a water level of water of the interior of the aquaculture box is higher than a height of the box surface drain hole,
a box waste drain hole different from the box surface drain hole, the box waste drain hole configured to drain both water and waste material from the box body, wherein water drained out of the box surface drain hole is separate from water drained out of the box waste drain hole; and
a box body connector located below the box waste drain hole at the lower end;
wherein the box base comprises:
a valve configured to connect to the box waste drain hole through the box body connector when the box body is attached to the box base,
wherein the valve comprises:
a box waste drain pipe positioned below the box waste drain hole, wherein the box waste drain pipe is configured to store water during the water storing stage when the crustaceans are being fed and to drain both water and waste material from the aquaculture box during the water draining stage after feeding,
a buoyant ball movable between the box waste drain hole and the box waste drain pipe, wherein the buoyant ball is configured to float up towards the box waste drain hole and seal the box waste drain hole on the box body to prevent water from flowing out of the aquaculture box during the water storing stage, wherein a diameter of the box waste drain hole on the aquaculture box is smaller than a diameter of the buoyant ball, and wherein the buoyant ball is configured to drop down towards the box waste drain pipe when the box waste drain pipe drains water and waste material from the aquaculture box during the water draining stage, and
a ball block comprising an angled ridge protruding from the box base, the ball block being configured to prevent the buoyant ball from sealing the box waste drain pipe and allow water and waste material to flow down to the box waste drain pipe during the water draining stage,
wherein the box body connector comprises a connector guide that ensures the box body is aligned with the box base when the box body is attached to the box base, and
wherein the aquaculture box is connected to a closed aquaculture system for harvesting crustaceans, wherein after water is introduced to the closed aquaculture system through an input water pipe, water is retained in the box waste drain pipe and allows the buoyant ball to float up towards the box waste drain hole, and wherein upon cleaning, the closed aquaculture system releases water out of the box waste drain pipe, allowing the buoyant ball to drop down.
