Occurs from coastal to offshore surface waters of the northeastern Atlantic, Mediterranean, and nearby seas, especially productive upwelling areas.
The body is slender and silver with a blue-green back. Small dark spots may appear along the sides.
It swims in large schools and shifts depth between day and night. Schools tighten when predators approach.
It filters phytoplankton and zooplankton. Seasonal plankton abundance strongly affects growth.
Adults release eggs into open water, and larvae drift as surface plankton. Spawning seasons vary by region.
Pilchards have long been canned, salted, and eaten fresh. They are also important prey for seabirds, larger fish, and dolphins.
