New antennas bring better Coho tracking
A new and improved tool that tracks salmon survival in Lagunitas Creek was installed on ranchlands west of Point Reyes Station last month, potentially changing the way the Marin Municipal Water District manages the watershed. Every year, ecologists implant a rice-sized microchip in hundreds of juvenile Coho salmon. Now, antennas anchored at the mouth of the creek will register their passage when they swim to or from the ocean.
