Final answer:
Restaurant owners should be aware of the shift towards aquaculture and sustainability efforts in fisheries, as these practices ensure a steady supply of seafood and support small-scale fisheries that are important for future sustainability.
Step-by-step explanation:
The passage from NOAA's statement that would be important to restaurant owners is the section that discusses the opportunity for commercial fishermen to look to aquaculture as a complement to their fishing activities. With the prospect of climate change mitigation leading to a reduction in global fleet capacity, more attention may be paid to small-scale fisheries and sustainable practices. As fish stocks decline due to overharvesting and ecosystem changes, practices like diversifying income sources by adding aquaculture and focusing on environmental sustainability can be beneficial not just for fishermen but also for restaurant owners relying on a steady supply of seafood.
