Fish Farming of the Future...!!

Aquaculture produces around half of the fish eaten worldwide, and since wild stocks are waning and global demand for fish is increasing, fish farming is destined to play a big role.National Geographic reports on a possible future of aquaculture, which includes free-floating, autonomous fish farms that move through the open ocean that mimic the movements of wild schools. Scientists are working on remote control cages:

...[A]utomated cages could herald an entirely new form of fish farming.

They might be turned loose to mimic natural systems by following carefully chosen ocean currents. The robotic fish farms could help lead to larger, healthier crops of farmed fish far from crowded coastal areas, where farmed fish both suffer from poor water quality and, by producing waste, add to water woes.

Cages might even generate their own electricity by harnessing solar energy, wave energy, or other forms of renewable power.
