Stock Status within the North Sea Herring
Key Findings
- Herring (Clupea harengus) has a wide distribution in the continental shelf waters of the North Atlantic and generally form dense pelagic shoals that maintain annual migration patterns between feeding, spawning and overwintering grounds. In Scottish waters, they spawn inshore during spring and offshore during autumn. The spring-spawned herring have been found to have longer lifespan, reach maximum size and produce fewer, heavier eggs that yield large larvae compared to autumn-spawned ones that undergoes unfavourable environmental conditions with less progress in their developmental stages over the winter months. They also differ from other marine fish as they are dependent on specific benthic spawning habitats to lay their sticky benthic eggs, forming dense carpets in highly localised areas, and increases vulnerability to mortality due to anthropogenic pressures such as bottom towed gear and toxins. In Scotland, herring has been an important species for subsistence and commercial species since the Neolithic times. The species is a Priority Marine Feature (PMF) in both territorial and offshore Scottish waters.
- North Sea Herring are considered to be a 'Good Choice' by the Marine Conservation Society.
- Landings for local ports are not listed within Scottish Fisheries Statistics. Combined Scottish catches are shown in Table 1.
- Catches of Herring are highly variable over time with periods of boom and bust.
