Stock Management in aquaculture refers to overseeing and controlling fish populations in farms or hatcheries. It's like inventory management, but for living creatures. This includes tracking how many fish are in each pond or tank, monitoring their growth, planning feeding schedules, and making decisions about when to move or sell fish. It's a crucial skill because it directly affects farm productivity and profitability. Think of it as being similar to herd management in traditional farming, but for fish and other aquatic species.
