Bombay duck is not a duck at all. It’s a saltwater fish found primarily off the western coast of India, prized for its delicate, melt-in-the-mouth texture when fresh and its intensely pungent smell when dried. Scientifically known as Harpadon nehereus, it belongs to the lizardfish family and is one of the most commercially important catches in the Indian states of Maharashtra and Gujarat, which together account for over 98% of India’s Bombay duck landings.
Why a Fish Is Called “Duck”
The name traces back to British colonial India. When the British shipped this fish from Bombay (now Mumbai) to other parts of the country by train, those rail services were called “Bombay Dak,” with “dak” being the Hindi word for mail. Over time, British speakers anglicized “dak” into “duck,” and the name stuck. The fish itself goes by many regional names across India: bombil in Marathi, bumla in Gujarati, loitta in Bengali, and vangaravasi in Tamil.
What It Looks and Feels Like
Bombay duck is a small, slender fish, typically around 16 centimeters long and weighing under 30 grams, though larger specimens exist. Its body is semi-translucent with a soft, almost gelatinous texture that sets it apart from most other fish. The flesh is extremely delicate and highly perishable, which is why it has historically been dried for preservation and long-distance transport.
Fresh Bombay duck has a faint but noticeable smell. Dried Bombay duck, on the other hand, is famously pungent. The odor is strong enough that dried bombil is typically stored and transported in airtight containers. That smell is polarizing: people who grew up eating it consider it essential to the experience, while newcomers can find it overwhelming.
Where It’s Caught
The fish is found across parts of the Indo-Pacific, but its commercial fishery is concentrated along India’s western coast, stretching from Ratnagiri in the south to Jaffrabad in the north, along the Gulf of Cambay. Key landing centers include Versova, Satpati, Bassein, Arnala, and the well-known Sassoon Docks in Mumbai.
Fishermen catch Bombay duck primarily using “dol” nets, a type of bag net positioned to take advantage of strong tidal currents. The net is set in place and retrieved before the tide turns. In Gujarat, gill nets are also common in inshore waters. The fishing season varies by region: Gujarat’s fishermen work mainly from June through January depending on the zone, while Maharashtra sees catches year-round, with the highest yields in the October-to-December quarter.
The species is currently listed as Near Threatened on the IUCN Red List, assessed in 2018. This classification reflects concerns about population trends driven by fishing pressure rather than an immediate crisis, but it signals that the fishery needs careful management to remain sustainable.
How It’s Eaten
Bombay duck is prepared in two fundamentally different ways: fresh and dried.
Fresh bombil is a staple of Mumbai’s coastal cuisine. The most iconic preparation involves coating the fish in a spiced semolina (rava) crust and deep-frying it until crisp on the outside while the flesh inside practically dissolves on the tongue. That contrast between the crunchy exterior and the soft, almost custardy interior is what makes it irreplaceable in the eyes of its fans. Food writers often note that Bombay duck has no real substitute because of this unique texture.
Dried Bombay duck is a different experience entirely. The fish is laid out in the sun, traditionally on bamboo racks along the coast, and dried until it becomes firm and intensely flavored. Dried bombil can be fried until crisp and eaten as a side dish, crumbled into rice, or added to curries and chutneys for a deep umami hit. Quality varies widely: traditionally sun-dried fish from local markets can develop a grayish or dark brown color, rancid odors, and even insect infestation if not handled well. Improved drying methods using controlled-environment dryers produce a noticeably better product in color, texture, and shelf life, especially when stored in sealed packaging at refrigerator temperatures.
Nutritional Profile
Bombay duck is a lean, protein-rich fish. On a dry weight basis, it can contain up to 70% protein and only about 3% fat, making it one of the more protein-dense fish options available. It’s also exceptionally high in calcium, with dried Bombay duck containing between 1,500 and 2,500 milligrams of calcium per 100 grams. For context, a glass of milk has roughly 300 milligrams.
The mineral content goes beyond calcium. Dried preparations are rich in potassium, magnesium, iron, and zinc. Researchers have explored using Bombay duck meal as a base for protein- and calcium-fortified snack foods, which speaks to how nutrient-dense this small fish actually is. Fresh bombil is naturally lower in these concentrated nutrients since drying removes water and concentrates everything else, but it remains a solid source of lean protein.
The EU Import Controversy
Bombay duck gained international attention in the early 2000s when the European Union restricted imports of certain dried fish products, including dried bombil, on hygiene grounds. The restrictions were part of broader tightening of food safety rules after the 2001 foot-and-mouth disease crisis, when the EU eliminated temporary exemptions that had allowed personal consignments of meat and animal products to enter without veterinary certification. For the South Asian diaspora in the UK, where dried Bombay duck had been a grocery staple, the restrictions were a significant cultural loss. The rules have evolved over time, and the EU currently allows travelers to bring in up to 20 kilograms of fishery products for personal use, though commercial imports of dried fish still face strict hygiene certification requirements.
