The Curonian Lagoon and the coasts of the Baltic Sea are perfect locations for recreational fishing. The following types of fishing with a fishing-rod are common here: fishing with a float rod, a bottom rod, a spinning rod, drift fishing and fishing from a boat. Recreational fishing is possible here all-year round. Yet, the most popular fishing seasons are from April through June and from August through October. The most important types of fish caught by fishermen are the common bream (Abramis brama), the European perch (Perca fluviatilis), the zander (Lucioperca lucioperca), the common roach (Rutilus rutilus) and the vimba bream (Vimba vimba).
In wintertime, one can go ice fishing on the frozen Curonian Lagoon. In wintertime, the burbot (Lota Lota) and the European smelt (Osmerus eperlanus) are caught. In spring and autumn, amateur fishers can catch the European plaice of the Baltic Sea (Pleuronectes platessa baltica), the European flounder (Platichthys flesus), the Baltic herring (Clupea harengus membras), the cod (Gadus morhua callarias), the turbot (Scophthalmus maximus), the salmon (Salmo salar) and the brown trout (Salmo trutta trutta) in the Baltic Sea.
Those who want to engage in recreational fishing in the Curonian Lagoon and the Baltic Sea must purchase permission, i.e. a recreational fishing licence.
The licence gives the green light to fishing in all the state unleased bodies of water where fishing is not limited. The fisher’s licence is issued on the ALIS platform http://alis.am.lt/ at Perlas terminals, Maxima trade centres, the e-ticket system Tiketa and Narvesen kiosks.
Visitors from abroad can only have the fishing licence bought by a Lithuanian citizen via the ALIS platform http://alis.am.lt/ In order to do so, one has to opt for the website’s English version and provide his/her date of birth instead of a personal number. Citizens of foreign countries can also purchase the licence at a Perlas terminal. In this case, one has to provide his/her date of birth and specify what type of licence one wants to purchase.
Recreational fishing is available free of charge to children up to 16 years old, the disabled and the retired.
