Observational analysis reveals seasonal and annual variations in herring muscle fatty acid profiles, suggesting dietary copepod shifts drive healthy omega-3 levels.

Key Points

To determine how the time and geographical location of catch affect the fatty acid composition and omega-3 polyunsaturated fatty acid content in Atlantic herring.
Analyzed muscle tissue fatty acid composition across N=963 herring (Clupea harengus L.) harvested between 2001 and 2003.
Evaluated catches across Danish waters, including the Baltic Sea, Skagerrak, Kattegat, and northern, western, and eastern sectors of the North Sea.
Assessed correlations between omega-3 levels (EPA and DHA) and biological variables such as sex, age, maturity, size, and spawning type.
Fatty acid composition varied primarily by season and year rather than catch location, with EPA peaking during summer while DHA showed no distinct periodic trends.
EPA content typically ranged from 4% to 8%, but spiked to an extraordinary 11% in northern North Sea herring caught in May 2003 compared to their lowest levels in the same area three months prior.
Biological factors such as maturity, spawning type, size, sex, and age did not correlate with the sudden surge in EPA, pointing to dietary variations such as calanoid copepods.
