Underwater camera as light sensor

A system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:
• obtaining, by a camera system that includes an upward-facing camera and one or more side-facing cameras, images of a surface of water captured by the upward-facing camera facing towards the surface of the water from a depth within an enclosure that encloses aquatic livestock;
• determining that the depth of the upward-facing camera satisfies one or more depth criteria;
• in response to determining that the depth of the upward-facing camera satisfies the one or more depth criteria, determining from the images of the surface of the water that were captured by the upward-facing camera, an ambient light metric at the depth;
• determining that one or more action criteria are satisfied based on the ambient light metric at the depth;
• and
• based on determining that the one or more action criteria are satisfied based on the ambient light metric at the depth, initiating performance of an action to be performed for the aquatic livestock.

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• determining that one or more action criteria are satisfied based on the ambient light metric at the depth;
• and
• based on determining that the one or more action criteria are satisfied based on the ambient light metric at the depth, initiating performance of an action to be performed for the aquatic livestock.
