Egg Frame

The FCCL is testing the possibilities of utilizing an egg frame created by the Lake Suwa Fishing Collective at Hokkaido, Japan, for future restoration of Delta Smelt in the Delta. The frame was designed for hatching Wakasagi (Hypomesus nipponensis) into a body of water with constant flow. The water flow condition around the eggs in the frame will be studied using computational flow dynamics and the results will be used to suggest a suitable environment for applying the egg frame in the Sacramento-San Joaquin estuary.
