As of Sunday, Nov. 25, the Stanislaus River fall-run salmon migration is at 4,378 salmon. For comparison, the season total was 7,606 salmon at this time last year. Salmon are born in fresh water, migrate to the ocean to grow to adulthood, then migrate back to fresh water to lay their eggs. Scientists call this type of fish “anadromous.” Other anadromous fish include lamprey, sturgeon, and American shad.
Funding for salmon monitoring at the Stanislaus weir is provided by the Oakdale Irrigation District, South San Joaquin Irrigation District, and Tri-Dam. Data collection is conducted by FISHBIO. For more information, visit www.fishbio.com.
