Sardines and pilchards are small, oily fish that are often confused with each other. Many people assume they are two different species, while others believe they are the same fish with different names. This content will clarify the relationship between sardines and pilchards, their characteristics, and how they are classified in different parts of the world.
Understanding Sardines and Pilchards
What Are Sardines?
Sardines are small, silvery fish that belong to the Clupeidae family, which also includes herring. They are commonly found in temperate and subtropical waters worldwide. Sardines are known for their high omega-3 fatty acid content, making them a nutritious choice for a balanced diet.
What Are Pilchards?
Pilchards also belong to the Clupeidae family and share many similarities with sardines. They are slightly larger and are often found in schools near coastal areas. Pilchards are popular in canned fish products and are consumed worldwide.

The terms ‘sardine’ and ‘pilchard’ are often used interchangeably, but their classification can vary depending on regional naming conventions and fish size.
- Size-Based Classification In many cases, sardines and pilchards are the same species, but the difference lies in their size. Generally, smaller fish (under 15 cm) are referred to as sardines, while larger ones (over 15 cm) are called pilchards.
- Regional Differences The name varies by country. In some regions, people use ‘sardine’ for all young fish, while ‘pilchard’ is used for mature ones.
