Facts about Herring
- 09
Young herring can identify and follow chemical trails left by older members of their species, allowing juvenile fish to learn optimal migration routes from experienced populations.
- 08
Herrings possess exceptional hearing abilities thanks to specialized bones connecting their swim bladders to their inner ears, allowing detection of frequencies as low as 10 hertz.
- 07
At least 181 herring species exist across the world's oceans and some freshwater systems, with the Atlantic herring being the most commercially important for global fisheries.
- 06
Herring migrate distances up to 3,000 kilometers annually between deep ocean feeding grounds and shallow coastal spawning areas, following complex routes shaped by temperature and currents.
- 05
A single herring can produce up to 40,000 eggs during spawning, allowing populations to recover quickly from heavy fishing pressure.
- 04
In schools off northern Europe, herring bones were historically used as fertilizer and fuel source during the 18th and 19th centuries due to their high phosphorus content.
- 03
The Pacific herring roe fishery in British Columbia generates approximately 25 million dollars annually, with Japanese markets valuing the eggs as kazunoko, a traditional sushi ingredient.
- 02
During spawning season, Atlantic herring produce specialized sound frequencies between 100 and 3000 hertz through their swim bladders, enabling underwater communication with other fish.
- 01
Approximately 3 million tons of herring are caught annually worldwide, making them one of the most harvested fish species by commercial fisheries.
