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.

A circular integrated ecological breeding and planting system including a plurality of units capable of growing vegetables, producing worms, breeding and raising chickens, and growing seaweed is provided to collectively construct a simplified simulated food. It not only unifies the lower and upper ecological food chains, but also minimizes pollution and undesirable waste. The system is particularly suitable for enclosed and intensive production within a single enclosed building to greatly reduce the production cost. This proposed eco-agricultural model has applications beyond its current configuration and can be applied to grow other plants, and to breed and raise other animals in the future.

An aquaculture system can include an aquafarm with one or more aquatic pods of aquatic organisms and a remote device to manage the aquafarm. An aquatic pod may be associated with an aquatic structure with a buoyancy system and a control device to automatically perform daily farming functions. The aquatic structure may include an enclosure to hold the aquatic organisms. The control device may be configured to use a smart buoyancy assistant to control the buoyancy system and to determine the farming task to perform in response to environmental stimuli. The remote device can receive data representing crop metrics, harvest results, and sensor data. The remote device can aggregate data from multiple aquatic pods and correlate the data to generate aquaculture models to improve the harvest results. The remote device can generate overview and maintenance reports for the aquafarm.

Provided is a device for flipping or rotating a floating aquatic cage to mitigate biofouling, and for farm management, such as to carry out maintenance and facilitate harvesting, particularly the style of floating cage used in farming oysters and other shellfish. The device includes a hollow frame or housing which defines a path through which the floating aquatic cage may pass, including entrance and exit openings; and one or more guide elements positioned on an inside surface of the hollow frame or housing. The one or more guide elements form an obstruction to opposing corners of the floating aquatic cage, and impart a turning force in such a manner as to rotate the floating aquatic cage.

A cephalopod feeder, a cephalopod feeding method using the cephalopod feeder, and a cephalopod fed with the cephalopod feeder. The cephalopod feeder includes an outer shell having a recessed portion; and feed disposed in the recessed portion.

A method for planting marine grass seed via a seed assembly comprising the steps of: selecting a body of water and area suitable for eele grass and shellfish, wherein the body of water has a bottom wherein shellfish can sufficiently bury themselves; selecting a living shellfish; placing a drop of non-toxic biodegradable adhesive on the shell of the living shellfish; positioning a grass seed to touch adhesive; waiting a predetermined time period for the adhesive to cure; and deploying the seed assembly into the body of water, wherein the seed assembly comprises the living shellfish, the drop of adhesive, and the positioned grass seed, wherein the body of water has a bottom where the shellfish can bury themselves sufficiently to bury the grass seed.

An aquafarming system is provided that includes a cultivating barrel with a multi-floor net assembly for the cultivation of shellfish creatures or the like. In the aquafarming system, the use of the multi-floor net assembly allows an increased cultivating area such that the quantity of the shellfish creatures being cultivated can be increased to thereby increase the productivity. At the harvest time, the multi-floor net assembly can be lifted up so as to be separated from the cultivating barrel such that the cultivated shellfish creatures can be easily and conveniently collected to reduced labor time and cost.
