My sister works at a large inland hatchery, raising atlantic salmon from egg to smolt, and its been neat to watch the investment, automation, and optimization going on there. For instance, they used to vaccinate hundreds of thousands of smolts by hand, and now there is a machine to do it. They used to lay the eggs out flat in trays and use a turkey baster to pick out duds, now there is a machine to do it. Now most of the human effort comes from moving fish and monitoring the processes.
