Lagoon fishing is seldom practised nowadays and perhaps the form most typical of the lagoon landscape is fishing with so-called “grasiui e cogoi”. “Seraja”, or “seragia”, is an ancient technique of capturing fish that employs a barrier, a “grasiul”, once woven in reeds and now made of netting, which is held in place by stakes and closes off a section of lagoon; “cogoi”, 5-metre long sacks made of netting are placed along the perimeter of the “seragia” at 35-metre intervals and once the fish and crustaceans are in, they can no longer get out. Thanks to the movement of the tides, the “seraje” capture common prawn (locally called “schie”) in winter and smelt in April and May, as well as flounder, eels and sea bass. The stretches of lagoon available for fishing are chosen by drawing lots (“toco”) at the start of each season, the “toco de Quaresima” taking place in April and the “toco de peschere” in autumn. This type of fishing depends on migration from the sea to the lagoon and vice versa. In springtime the fry enter the lagoon attracted by the plentiful food supply, while in the autumn, when the shallow waters in the lagoon rapidly become colder, the grown fish head for the open sea and deeper water, where the temperature is more stable, especially off the coast of Istria, where they reproduce.
