Öhnberg started the A. B. Öhnberg Canning Company which included the Ejderns brand, all now owned by Abba Seafood. They produced a special sort of caviar that is still one of the most popular sandwich spreads in Sweden. Lysekil Caviar, often referred to as creamed smoked roe, differs from normal caviar in that its main ingredients are cod roe, canola oil, sugar, onion, tomato sauce and salt; it is also often seasoned with dill. Kalles Kaviar is the best-known brand. Granite quarries and stonemasonry were part of Lysekil's industries in 1850–1950. The granite was much in demand for buildings and street paving in Britain, Germany, Denmark, Belgium and Argentine. In 1909, there were five quarries in Lysekil. Tourism became a vital source of income for Lysekil in the 1850s. The town was established as a fashionable bathing resort. In 2018, tourism is still vital for the town's economy. It has branched out to include more activities underwater diving, kayaking, sports fishing and seal safaris. One of the largest oil refinery in Sweden, Preemraff Lysekil, situated a few miles outside the town, is one of the main employers in the area. Plans to build a refinery near Lysekil started in 1945 when the Swedish consumer-owned oil company Oljekonsumenters Riksförbund (OK), was formed. Negotiations for building the refinery were long and hard, and it was not until 1975 that it was inaugurated. 2017 port project proposal In late November 2017, pro-Beijing businessman and Chinese People's Political Consultative Conference (CPPCC) member Gao Jingde, on behalf of a consortium led by Hong Kong-listed Sunbase International (Holdings) Ltd of which he is chairman, proposed building Scandinavia's largest port at Lysekil. Transport In 1910, Lysekil was connected with the rest of the Swedish railway network through the Lysekil Line, a branch railway of the Bohus Line. Passenger transport in the line, ceased in 1983, while some freight use remained. Maintenance in the line continued until 2016 with only a few trains running during summer. On 9 December 2018, all maintenance and traffic on the line will cease as the switch in Smedberg is disconnected. The public transportation bus network in Lysekil is operated by Västtrafik. The network also includes a ferry, M/S Carl Wilhelmson (line 847), between Lysekil and Fiskebäckskil on the other side of Gullmarn fjord. Another ferry service across the fjord from Lysekil, is the car ferry operated by Trafikverket Färjerederiet. Sights and events
