Read the passage and answer the questions.
AI continues to advance in aquaculture to extend beyond caged fish. In particular, smart fish farming technologies can be applied to seaweed farming. Seaweed is as valuable a source of food as fish. It’s also a source of fuel and an important ingredient for cosmetics, fertilizers, and other medicinal and industrial products. As such, ongoing research is exploring various ways AI can help in the seaweed industry, including the use of autonomous underwater vehicles (AUVs) and swarm robotics. Using cameras and sensors, AUVs can do many of the analytical and diagnostic tasks on seaweed farms.
