Feeding market-size salmonids in depuration systems: Effects on off-flavor, weight loss, and fillet quality

Presented by John Davidson, research scientist at The Freshwater Institute

Depuration is a proven finishing procedure that effectively remediates off-flavor in RAS-produced salmonids; however, fish weight loss can occur during extended feed withholding periods that coincide with this process. Therefore, research was conducted to evaluate the feasibility of feeding market-size Atlantic salmon and steelhead rainbow trout in depuration systems. These studies found that feeding reduces fish weight loss without negative impact to off-flavor elimination rate when these species are purged in pre-disinfected partial reuse systems supplied with water containing negligible off-flavor levels.
