2005 EGG TAKE REPORT:
On November 24, 2005, we collected coho brood stock as the major feature of our salmon enhancement project. About 4700 eggs were taken. They were first fertilized, counted and placed in a tray in the special equipment in incubation room.
Every day one of our volunteers clean the filter and monitor water temperature. This water continuously runs over the eggs in the incubation equipment. Coho salmon eggs reached the "eyed egg stage" by the end of January, 2006. At this stage, a distinct eye is visible through the egg shell - see the pictures At the beginning of February 2006, the eggs hatched into alevin (fry with yolk sacs attached). The alevin continue to develop using the yolk material for growth. During this period, the young salmon are very sensitive to light, so the incubation room is kept dark as much as possible. By March, the alevin will absorb most of their yolk sacs and their bellies will "buttoned-up". Eventually the fish will be removed from the trays and placed in an outside trough called a capilano trough.
2006 Egg Take Report
On March 16, 2006, we moved fry from incubation room to an outside trough. Every day we feed the fish, clean the trough and monitor water temperature in order to raise coho until they are large enough to go to the rearing pond, and eventually to be released into creek.
