Sardine
The word sardine first appeared in English during the 15th century. It arrived as a loanword from French, which had borrowed it from Latin. The Latin term traces back to Ancient Greek words like sardínē or sardĩnos. One theory suggests these roots connect to Sardinia, the Italian island where sardines were once thought to be abundant. This explanation feels shaky to historians. Athens sits over 1000 km away from Sardinia. It seems unlikely that ancient Greeks obtained fish from such a distant place during Aristotle's time. Another possibility links the name to the reddish-brown color of some sardine flesh. This hue resembles varieties of red sardonyx or sardine stone. That gemstone derives its name from Sardis, the capital of ancient Lydia in western Turkey. The ancients knew this stone as sard or carnelian. Myceneans did trade with Sardinians during the latter Bronze Age. Yet the linguistic path remains disputed among scholars today.
Sardines occur across several distinct genera within the herring suborder Clupeoidei. FishBase lists at least six species simply called pilchards. Over a dozen other species carry just the name sardine. Many more exist with adjectives qualifying their basic names. The United Kingdom's Sea Fish Industry Authority classifies young pilchards as sardines. One criterion states fish shorter than 25 cm are sardines while larger ones become pilchards. The FAO/WHO Codex standard for canned sardines cites 21 species that may be classed as sardines. Genus Dussumieria includes the Rainbow sardine and Slender rainbow sardine. Genus Escualosa contains the Slender white sardine and White sardine. Genus Sardina holds the European pilchard known as true sardine. Genus Sardinella encompasses 25 different species ranging from Bali to Brazil. Genus Sardinops covers Japanese, Southern African, and South American varieties. Sprats sometimes market themselves as sardines too. The European sprat appears as the brisling sardine in some markets. Commercially significant species vary widely in size and conservation status.
Sardines feed almost exclusively on zooplankton wherever it is abundant. They congregate in schools whenever plankton concentrations rise high enough. These fish approach the surface at night to feed on the tiny organisms. Their life cycle characteristics support massive population numbers in marine environments. Sardines occupy a low trophic level within ocean food webs. This position keeps them relatively free of contaminants like mercury compared to other edible fish. They produce minimal greenhouse gas emissions during their production cycles. A typical sardine reaches maximum lengths between 15 cm and 30 cm depending on species. Some reach ages up to six years while others live shorter lives. The Indian oil sardine measures about 24 cm at maximum length. The Brazilian sardinella grows to roughly 31 cm. Conservation statuses range from Least Concern to Vulnerable across different populations. The Madeiran sardinella currently holds a Vulnerable classification according to IUCN records.
Typically, sardines are caught with encircling nets known as purse seines. Many modifications of these encircling nets exist including traps or fishing weirs. Fishing weirs form stationary enclosures made of stakes into which schools swim along the coast. Fishermen catch the fish mainly at night when they approach the surface. After harvesting, workers submerge the fish in brine before transport to shore. Sardines serve commercial purposes for bait, immediate consumption, drying, salting, or smoking. Reduction into fish meal or oil represents another major use case. The chief use remains human consumption globally. Fish meal serves as animal feed while sardine oil manufactures paint, varnish, and linoleum. Commercially significant species include the South American pilchard and Japanese pilchard. Pacific sardine stocks collapsed dramatically by April 2015. The Pacific Fishery Management Council voted to halt the current commercial season in Oregon, Washington, and California. About 100 fishing boats held permits though far fewer actively fished at that time. The ban was expected to last more than a year.
Sardines provide humans with protein, omega-3 fatty acids, and micronutrients. Canned sardines contain 67% water, 21% protein, and 10% fat. They hold negligible carbohydrates within their composition. A reference amount supplies 185 calories of food energy per serving. These fish offer rich sources of vitamin B12 reaching 375% of Daily Value. Phosphorus content reaches 29% DV while niacin hits 26% DV. Moderate sources include riboflavin, pantothenic acid, calcium, and sodium at 18% DV each. A 100 g serving provides about 7 g combined monounsaturated and polyunsaturated fatty acids. Sardines remain low in contaminants like mercury relative to other commonly eaten fish. Their production creates relatively low greenhouse gas impacts compared to larger seafood options. People consume them grilled, pickled, smoked, or preserved in cans. The USDA source confirms these nutritional profiles for canned varieties specifically. Dietary minerals found inside support bone health and metabolic functions effectively.
Pilchard fishing and processing became a thriving industry in Cornwall from around 1750 until approximately 1880. After that period the trade went into decline. Catches varied significantly year to year throughout the 19th century. In 1871 the catch reached 47,000 hogsheads while 1877 dropped to only 9,477 hogsheads. Each hogshead contained between 2,300 and 4,000 pilchards when filled with pressed fish. Filled containers weighed 476 lbs total weight. Most pilchards exported to Roman Catholic countries such as Italy and Spain where locals called them fermades. The chief market for oil was Bristol where it served machinery operations. Since 1997 sardines from Cornwall sold under the name Cornish sardines. March 2010 brought EU law granting Protected Geographical Status to Cornish sardines. The industry featured prominently in works by Stanhope Forbes and other Newlyn School artists. J.M.W. Turner painted St Mawes at the Pilchard Season in 1812. A traditional Toast to Pilchards referenced lucrative exports to Catholic Europe.
The United States sardine canning industry peaked during the 1950s before entering decline. Canneries in Monterey Bay failed in what became known as Cannery Row in Monterey County California. John Steinbeck set his novel of the same name there. The last large sardine cannery in the United States closed on the 15th of April 2010. The Stinson Seafood plant operated in Prospect Harbor Maine for 135 years before shutting down. In April 2015 the Pacific Fishery Management Council voted to halt the current commercial season. This decision affected Oregon, Washington, and California due to dramatic stock collapse. About 100 fishing boats held permits though far fewer actively fished at that time. The normal season would end the 30th of June each year. The ban was expected to last more than a year while stocks recovered. Popular culture adopted phrases like packed like sardines from early 19th century sources. The phrase appeared in The Mirror of Literature, Amusement, and Instruction from 1841. It translates French expressions about cramming people together tightly into small spaces.
