When to use
- Planning a feed type change (starter to grower, grower to finisher)
- Switching feed suppliers or formulations
- Communicating transition schedules to farm staff
- Documenting transition protocols for quality assurance

Do not use for
- For calculating feed ration amounts — this plans the ratio, not the total quantity
- For emergency feed changes where old feed is unavailable
Mix feeds thoroughly
Poor mixing leads to some fish getting only old feed and others only new feed, defeating the purpose of gradual transition.
Watch FCR during the transition
A temporary FCR increase of 0.1-0.2 is normal during transitions. If FCR increases by more than 0.3, the transition may be too aggressive.
Never transition during other stressors
Avoid feed changes during treatment, handling, or environmental stress events. One stressor at a time.

Method
Linear graduated transition ratios based on NRC (2011) and industry-standard feed management practices. Transition duration is user-configurable from 2 to 30 days. All processing is client-side.

Feed Transitions in Aquaculture
Feed transitions occur at multiple points in the production cycle: nursery to grower, grower to finisher, and when changing suppliers or formulations. Each transition is a stress event for the fish. The graduated mixing approach — blending decreasing proportions of old feed with increasing proportions of new feed — minimizes physiological stress and maintains consistent growth performance.
