Fish biomass, shape, size, or health determination

A system comprising:

• one or more computing devices and one or more storage devices storing instructions which when executed by the one or more computing devices, cause the one or more computing devices to perform operations comprising:
• obtaining one or more images of a fish;
• determining one or more key points associated with one or more features of the fish in the one or more images;
• generating a model of the fish based on the one or more key points associated with the one or more features of the fish;
• determining, using the model of the fish, a characteristic of the fish from among:
• a shortened abdomen, a shortened tail, scoliosis, lordosis, kyphosis, a deformed upper jaw, a deformed lower jaw, a shortened operculum, runting or cardiomyopathy syndrome (CMS);
• and
• outputting a representation of the characteristic of the fish for display or storage at a device connected to the one or more computing devices.
