Although this technology is currently in its infancy out here in the (so called) "real world" ... I can easily imagine that once the technology and techniques involved mature with additional research and testing, this could potentially become an exceptionally useful Life Support Engineering Strategy for Humaniti living in hostile environments (such as space). Combine the aquaculture (fish) with hydroponics (plants grown in water) with aeroponics vertical farming techniques (plants grown in air) ... and you've got a miniaturized close loop biome that provides meat proteins (fish) and vegetable proteins (plants) which is relatively sustainable with monitoring and supervision oversight using the appropriate knowledge and skills. Just add robots(!) to assist with the monitoring and supervision and you've got a lean crew requirement for managing a regenerative life support biome that is usable on a starship for a closed loop system that can be sustained in between annual overhaul maintenance cycles (just add fuel purification plant "waste byproduct chemistry" feedstocks).
