November 2, 2017 — Recently, Dr. William Sydeman of the Farallon Institute, published a study claiming that the abundance of anchovy near shore — especially in places like Monterey — is evidence that the population is collapsing.
Sydeman’s logic is based on an old argument that collapsed populations always shrink inshore. But there’s one big problem with that theory — it’s unsupported by scientific evidence. In fact, that logic was based on an old sardine theory that has since been debunked. There’s certainly no evidence that low anchovy biomass results in an increase in anchovy in the nearshore area of Central California.
In fact, the opposite is likely true. According to the Monterey Herald, the anchovies that flooded into Monterey Harbor in September were 3 inches long. Pete Guglielmo, an anchovy processor in Monterey, exclaimed, “Inside Monterey harbor and the outer break wall, you can walk on 3-inch anchovy. What a sight to see! They are running the air pumps in the harbor to keep them alive.”
In other words, the abundance of 3-inch (young-of-the-year) anchovy in the nearshore region implies that there is a strong 2017 year-class. A record abundance of young-of-the-year also was documented in scientific cruises going back to 2015, as well as observed by fishermen in both northern and southern California.
