An apparatus for containing, maintaining and raising oysters, mollusks and other aquatic life, the apparatus being formed of wood of sufficient buoyancy so that the structure will float on or in the surface of a body of water without additional buoyant elements. The apparatus has opening on each of two opposite sides and slats covering the top and the bottom of the box, the size of the holes and the spacing between the slats having dimensions such that the nutrient containing water body within which the structure has been deployed, may freely flow through the box while containing and maintaining the selected aquatic life within the apparatus. The device may also contain baffles within the interior space to keep the containing and growing aquatic life form shifting in the device as nutrient rich water passes therethrough.

A crawfish harvest system and method of harvesting crawfish from a crawfish pond, without entry into the pond by personnel or boats. A crawfish trap deployment and retrieval unit is positioned by a crawfish pond. One or more crawfish traps are attached to a main line, which is engaged with the deployment and retrieval unit and runs into the crawfish pond and around one or more turn points in the pond, forming an endless loop of main line. The crawfish traps can be deployed into and retrieved from the crawfish pond by the deployment and retrieval unit pulling the main line, without personnel, boat or other entry into the pond.

The breeding case for bivalves includes a submersible body having at least one housing receiving and protecting at least one bivalve and a framework. The framework is formed by two branches which extend respectively along two mutually perpendicular axes, the branches defining a determined number of housings. Each housing is equipped with a bottom and a protective wall which extends from the bottom to an upper edge at the upper portion of the submersible body. The case also includes at least one movement slide and locking mechanism for a locked position with the movement slide. The invention also concerns a bivalve breeding column having a determined number of breeding cases fitted one on top of the other. The method for bivalve breeding in connection with the bivalve breeding column is also part of the invention.

A modular aquaculture system, and method of using same, deployable in a body of water having a water column, the system including at least one carrier unit defining at least one chamber in which a plurality of containers can be placed. Each container is capable of holding a plurality of organisms to be cultured, and the chamber has at least one chamber inlet for water intake and at least one chamber outlet. The system further includes support structure having sufficient flotation to suspend the at least one carrier unit in the water column. At least one drive unit actively alters a rate of water flow through the at least one chamber and past the containers.

This invention relates to a confinement device for growing larvae or aquatic organisms in general, which allows the diversification of aquaculture. The device is modular and stackable. This invention relates particularly to a confinement device that makes it possible to keep larvae from multiple marine/aquatic organisms in confinement in their natural environment for them to undergo metamorphosis, maturation and settling of larvae that will subsequently become juveniles or seed for an industrial pre-fattening stage. The device also allows confining aquatic organisms in general, facilitating their development in culture. This invention also relates to a cultivation system and method comprising the use of said confinement device.

An apparatus and method for promoting macrobenthic growth in a waterway. The apparatus comprises a biodegradable net bag with a biodegradable panel insert that is adapted to receive a biomass Suitable for attracting and promoting macrobenthic growth. The method comprises providing a suitable net bag, filling it with an appropriate biomass, deploying it in a healthy waterway until macrobenthic growth has become established, and transporting and redeploying it in a second waterway requiring remediation.

A method for aquaculture including a fastener that allows for a float to be easily detached from and securely reattached to an aquaculture cage. The method provides multiple toolless approaches to submerse an aquaculture cage that is buoyant in water when attached with a fastener to a hollow float defining a volume filled with air. The method includes in a first approach, detaching the hollow float from the aquaculture cage by releasing the fastener without using a tool to allow the cage to sink in the water and in a second approach, with the hollow float attached to the aquaculture cage, at least partially filling the float with fluid to fully submerse both the cage and the hollow float beneath a surface of the water.
