CATCHING THE YOUNG FISH. 

This occurs in certain periods of the year when the young fish enter the lagoon and the river mouths spontaneously.The amount of young caught is not always sufficient in which case artificial reproduction is used.

DISTRIBUTION

In March, April and May the young fish are put into breeding basins.

WEIGHT INCREASE  - This depends on the alimentary resources found in the environment and is usually linked to the renewal of the water in the basins which occurs three times a year: in early spring, during the growing period and during harvest time.

HARVESTING - This takes place between October and December and is based on the fish's tendency to return to the sea, where it is driven by reproductive stimulus and by the reduction of the temperature of the water in the basins. This is done  letting warmer sea water into the basins which acts as a call for the fish, which are then channelled, at first into the "lavoriere" and then into the "otela" where they are caught and selected.

WINTERING is a series of operations carried out in the winter canals to protect the fish which have not  reached marketable size yet.
