This is what we learned. Forage fish spawn at high tide just below the highest tide line -- in 6 to 10 inches of water, at the top of their reach on the beach, during the brief slack-tide. The embryos attach themselves to small pebbles in the top couple inches of beach substrate.
So my family has signed up for this forage fish survey. We'll be taking samples as we learned at the workshop and sending them in for analysis, and hopefully the very intelligent and courageous woman who is heading this important project can continue her advocacy on behalf of forage fish spawning areas.
