FishTick greatly improves the fish-counting procedure, giving you many advantages:
Less handling stress (After using FIshTick, USFWS found that handling delayed migration and reduced survival to the spawning grounds.)
Minimize holding time
Less labor intensive
Better sex identification
Better external tag detection
Permanent record for review
More accurate counts (fish often escape from live boxes)
Fish go from the wheel down a chute to a live box, where they are netted out.
