Salmon Update!

November 19, 2010

The salmon eggs are have continued to develop.  The eggs are starting to show shadows of the developing embryo.  Veins and blood vessels are visible on many of the eggs.  I believe we have one fatality among the eggs.  The key characteristic for determining dead eggs is the color.  Pale cream/white is commonly associated with death.  The dead egg can be seen in today's picture.  This is WLACE's first salmon fatality!

The Egg

When adult salmon enter the river to spawn, each female salmon can lay 2,000 to 2,500 eggs.  The eggs are pink/orange in color.  The average size ranges from 6 to 9 mm in diameter.  Salmon eggs consist of a  transparent membrane that protects the egg from predators or other disturbances while in the river.  Salmon eggs are very sensitive and one in 10 eggs will survive in the wild.
