Shoal Transfer

Shoal Transfer helps hatchery crews decide whether one measured live-fish move is ready to leave its holding tank. Begin with the fish count, sampled mass and usable water volume to expose biomass density. Add current dissolved oxygen, the local minimum and observed demand to estimate reserve minutes. At arrival, compare tank and receiving temperatures to schedule gradual acclimation, then calculate the remaining crew-time margin for the planned handling cycles. A combined Release Review identifies the limiting signal before the assessment is saved on the device. Saved transfers can be reopened in detail or removed from the log. Settings apply the hatchery's own planning limits to new reviews. The results support preparation and discussion; they do not replace live monitoring, animal-welfare procedures, oxygen-equipment checks or professional judgment.
