This year’s start feeding for fry from the earliest deliveries is in full swing. Reports so far have been very positive. Facilities which have reported the most successful start feeding have used a rapid temperature rise from 8-9 °C to 12-14 °C over a 3-4 day period. This temperature signal just before start of feeding stimulates the fry’s “swim up response”, causing the fry to swim up and ingest air to the swim bladder. This allows fry to regulate vertical swimming and move actively through the water column to find food.
