SANTA CRUZ — All this week, an influx of anchovies, thousands possibly millions of the baitfish, inundated the waters near the Santa Cruz coastline, drawing swarms of sea birds and stoking concerns at the Santa Cruz Small Craft Harbor.
Anderson said that the crew at the harbor deals with similar fish issues on a seasonal basis, and it is often in the summer and early fall when the baitfish tend to swamp the shoreline and Santa Cruz Small Craft Harbor. Anderson said that they have been fortunate not to experience a mass die-off in the harbor in recent years, which he said is in large part due to the help of the aerators. The fish seem to take the hint and leave after the system is switched on, because as Anderson pointed out, the devices serve a double function.
“It’s a large biomass,” said Anderson. “If the fish stay in here for long enough, there are so many of them that no amount of aeration or mitigation is going to help. The biomass will just overwhelm the aeration system and that’s when we have the die-offs.
Avid ocean swimmer Peggy Miles, who records the ocean water temperature for the Sentinel, also noticed the larger schools of anchovies this week with the sea bird swarms in tow. Miles said that she doesn’t mind the anchovies and even enjoys swimming through the massive schools of small fish. “When the light hits them as they’re moving, they’re silver and they reflect and they’re just gorgeous,” said Miles. “It’s a very special experience to swim with the anchovies.”
