An adaptor for coupling pipes together that has a pair of spaced apart pipe members disposed parallel to each other. Each of the pipe members include an opening at a top and at the bottom for receiving an additional pipe. A bridging member connects the pair of pipe members and defines a passage between the pipe members. The bridging member comprises an open top allowing access to the interior of the adaptor.

An aquaponic system, having at least one farming section; each farming section has an aquaculture unit, a vegetable farming unit and a water circulation unit; the aquaculture unit has an outer tank and an aquaculture tank inside the outer tank; the vegetable farming unit has a vegetable farming column and a water collection tank at a bottom part thereof; the water circulation unit has a filter tank, a water pump, and at least one guiding pipe extending from the aquaculture tank to the vegetable farming column; a water inlet of the filter tank is connected with a water outlet of the aquaculture tank; a water outlet of the filter tank is connected with a water inlet of the aquaculture tank; one end of the water pump is connected with the water collection tank, another end of the water pump is connected with the aquaculture tank.

A circulation type aquaculture method and a circulation type aquaculture apparatus which treat and remove ammonia harmful to fishes/shellfishes. The method includes a first step of finding an ammonia decomposition rate upon preliminarily treating cultivation water by using ozone or hypochloric acid so as to set a target remaining amount of ammonia after the decomposing treatment, a second step of finding the amount of ammonia in cultivation water so as to calculate a treating period of time required for reducing the amount of ammonia to the target remaining amount of ammonia based upon the ammonia decomposition rate of the first step, a third step of treating the cultivation water using ozone or hypochloric acid during the treating period of time calculated in the second step so as to treat and decompose ammonia in the cultivation water and a fourth step of returning the cultivation water to the aquaculture tank.

A seafood storage and/or transportation container is provided. The seafood container comprises a container, the container having a bottom wall, two side walls and two end walls. The container also comprises at least one channel, the channel having an inlet at the lower portion of the interior of the container, a hollow body that extends upward, and an outlet that communicates with the exterior of the container. The at least one channel assists in removal of water from the lower portion of the container, which will be accompanied by some of the waste product from the stored seafood. When a water source is provided overhead, the container of the present invention allows the stored seafood product to be submerged in water, while also obtaining a substantially complete turnover of water within the container (including waste products). This facilitates the mixing of water in the container by drawing away the possibly contaminated water from near the bottom of the container and pulling down the cleaner, oxygen rich water from near the top of the container. Preferably, there is a lid hingedly attached to the top of the seafood container, having at least one trough that serves to trap water as it passes over the lid. The water is retained in the trough until it enters the inside of the container through a plurality of holes contained therein.

An aquaculture system including, at least one grow-out tank; a fluid treatment system including a fluid treatment device, a recirculation pump and fluid connections to each of said at least one grow-out tanks for circulating fluid from each of the at least one grow-out tanks through the fluid treatment device; and at least one fluid delivering device which is connected to the fluid treatment system for delivering said circulated treated fluid to said at least one grow-out tank, which fluid delivering device includes an outlet which can be provided in a position within the at least one grow-out tank such that the treated fluid delivered out from the outlet will be delivered along a bottom of said at least one grow-out tank wherein the outlet of the at least one fluid delivering device is configured such that it can be rotated in order for delivering the fluid in different directions along the bottom of the grow-out tank, wherein the at least one fluid delivering device is configured for delivering the treated fluid to substantially the whole bottom of said at least one tank at a velocity which is enough for resuspending sedimented particles, wherein said fluid treatment system is connected to and is serving said at least one grow-out tank intermittently with time constraints which are based on cultivation conditions for an aquaculture in said at least one grow-out tank.
