“A Total Shock” – Japanese Sardines Detected in U.S. Waters
Genomic sequencing of Pacific sardines in 2022 and 2023 uncovered the presence of not just one, but two distinct sardine species in the California Current. When research scientist Gary Longo first reviewed the results of his genomic analysis of sardines, he thought he must have mixed up his samples. Besides the Pacific sardines common on the West Coast, many of the fish appeared to be another species. “It was a total shock,” he said. Then he compared their genetic code to other known species. “That was the ‘aha moment’ when we realized we were looking at a second species of sardine.” The analysis shows that of the 345 sardine samples collected during NOAA Fisheries’ 2021 and 2022 Coastal Pelagic Species Surveys, all of the fish in 2021 were Pacific sardines, but those collected in 2022 were a mix of Pacific sardines and Japanese sardines. more, >>CLICK TO READ<< 10:50
