A distribution device automates and meters distribution of feed in a commercial shrimp production facility utilizing a stacked shallow tank configuration. The device includes an elongated support surface positioned over and extending along an elongated tank having an open top. A shuttle moves along the support surface to move along a length of the tank. A hopper to hold feed is coupled to the shuttle. A spreader is in environmental communication with the hopper to distribute feed from the hopper and a meter is operationally coupled between the hopper and the spreader for controlling an amount of the feed delivered to and distributed by the spreader.

There is provided herein a method of treating a poikilothermic organism, such as marine bivalves, in a decreasing temperature environment which method comprises exposing the organism to a source of eicosapentaenoic acid (EPA) at temperatures of from 18° C. to about 12° C., and then exposing the organism to a source of docosahexaenoic acid (DHA) at temperatures of from about 11° C. to about 5° C. There is also provided herein a method of just conducting the first or second exposing step without the other, and also a method of using a decrease in temperature to catalyze the organism to produce EPA and/or DHA and/or non-methylene-interrupted fatty acids (NMIs).

A method for incubating an aquatic species includes introducing fertilized eggs of the aquatic species into a screened incubation container, introducing the screened incubation container into a vessel of an incubation module, circulating clean oxygenated water through the incubation module vessel, transferring successfully fertilized eggs from the incubation module vessel to an upweller of a hatching module, circulating clean oxygenated water through the upweller, transferring larvae that swim out of the upweller into a tray of a larvae holding module, circulating clean oxygenated water through the larvae holding module, transferring larvae that grow into a juvenile growth stage from the larvae holding module to a tray of a juvenile holding module, circulating clean oxygenated water through the juvenile holding module, and releasing juveniles from the juvenile holding module after a predefined growth period or after the juveniles grow to a predetermined size.

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.
