Pilchards are a type of small, oily forage fish that belong to the Clupeidae family, which also includes herring. Found in large schools near the surface of the water, they are a food source for many marine predators. Historically, these silvery fish have also been a significant food item for human populations, particularly in coastal regions. They are recognized scientifically as Sardina pilchardus and are prevalent in the Northeast Atlantic, Mediterranean, and Black Sea.
The Pilchard and Sardine Connection
The frequent confusion between the terms “pilchard” and “sardine” stems from their overlapping usage in different regions. Technically, a pilchard often refers to the mature, larger adult of the species Sardina pilchardus. These adult fish can reach lengths of up to 27.5 cm. The name “sardine” can be used to describe the juvenile fish of this very same species.
This distinction is not always consistent, as the term “sardine” is also broadly applied as a general classification for numerous species of small, oily fish packed in cans. For instance, the United Kingdom’s Sea Fish Industry Authority identifies sardines as young pilchards. An informal guideline suggests that fish under 15 cm are considered sardines, while those that grow larger are called pilchards. The international Codex standard for canned sardines recognizes 21 different species that can be marketed under the name.
Nutritional Profile
Pilchards offer a dense concentration of beneficial nutrients. They are particularly high in omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The fish are also a substantial source of high-quality protein.
Beyond omega-3s, pilchards provide a significant amount of vitamin D and vitamin B12. Canned versions that include the bones are an excellent source of calcium, contributing to bone density. As they are small and have a short lifespan, pilchards are low on the food chain and accumulate very low levels of mercury, making them a safe seafood choice for frequent consumption.
Culinary Uses
The most common way to find pilchards is canned, typically packed in tomato sauce, brine, or oil. The canning process softens the bones to the point where they are easily edible. Their flavor is distinctly rich and oily, which pairs well with acidic ingredients.
Fresh pilchards are also available, especially during summer months in coastal areas, and lend themselves to simple cooking methods. Grilling or frying them with a bit of salt and lemon highlights their natural taste. They can also be found smoked or salted. For a taste of tradition, the Cornish Stargazy pie famously features whole pilchards baked into a pastry crust, with their heads emerging from the top as if gazing at the stars.
