Which Water the Larvae Drank

Bore Drawdown and Source-Water Bacteria in Larval Guts at a Groundwater-Fed Finfish Hatchery

A research poster from the School of Underlying Conditions follows 14 larval cohorts through two spawning seasons at a bore-fed finfish hatchery whose bore is screened across two aquifer intervals, and uses 16S amplicon source tracking to ask how much of each larval gut community came from the bore. Once the standing water level fell below the upper screen top, the bore's median share of the seven-day gut rose from 9% to 30%, carried by bacteria found only in the deeper, iron-rich interval, and the share followed the water level rather than the hatch date.
