Alex Haro walks flume to recover juvenile lamprey

During Nov-Dec 2021 study in the Conte Fish Passage Complex (flume bldg), juvenile lamprey transformers were tagged and released in the 10' wide west flume to evaluate their response to various conditions including water velocity and light.  Alex Haro is shown here walking the 200'+ long flume to collect transformers not captured in trap or flushed downstream.
