Abstract

Techniques and systems for robotic aquaculture are described. In one embodiment, for example, a mariculture system may include an aquatic animal containment system operative to hold a population of aquatic animals, the aquatic animal containment system comprising an enclosed hull having a receptacle configured to receive a mechanical core, the mechanical core configured to store at least one sub-system to implement at least one function of mariculture system, and a position management system operative to maintain the enclosed hull at a depth below a surface of a body of water. Other embodiments are described.

First claim

What is claimed is:

1. An aquaculture system, comprising:
an aquatic animal containment system configured to be deployed in a body of water and to hold a population of aquatic animals within contained water, the aquatic animal containment system including a fluid-impermeable hull, the fluid-impermeable hull being a closed containment structure configured to be submerged beneath a surface of the body of water and to maintain isolation of the body of water from the contained water, the fluid-impermeable hull including a receptacle; and
a feeding system housed in a mechanical core, the mechanical core configured to be deployed within the receptacle in an arrangement that enables delivery of food from the mechanical core to the population of aquatic animals within the fluid-impermeable hull of the aquatic animal containment system.

2. The aquaculture system of claim 1 , wherein the feeding system includes at least one processor and wherein the at least one processor is configured to estimate size of the aquatic animals and to compute a ration of the food for delivery based on the size estimated.

3. The aquaculture system of claim 1 , wherein the feeding system includes a take-up reel, food release mechanism, and dispenser, wherein the food includes fish gurry, insect protein derived from waste vegetable produce, or a combination thereof, wherein the food is packaged in aliquots in sealed bags, wherein the sealed bags are inserted in a shrink tube that is heat shrunk to produce a strip, wherein the strip is threaded through the dispenser and attached to the take-up reel, and wherein the take-up reel is configured to pull the strip to cause the sealed bags to contact the food release mechanism to release respective food content of the sealed bags into the dispenser, the dispenser oriented to release the respective food content during delivery of the respective food content into the contained water.

4. The aquaculture system of claim 1 , wherein the food is pelletized food and wherein the feeding system is further configured to dispense the pelletized food from vacuum-sealed bags.

5. The aquaculture system of claim 1 , wherein to deliver the food, the feeding system is further configured to move a packaged aliquot of food pellets to contact a food release mechanism to release the food pellets into a dispenser within the fluid-impermeable hull, the dispenser oriented to release the food pellets during delivery of the food pellets into the contained water.
