Khazan land - fish production
The zone immediately upstream the sluice gate, has a depression (‘poiem’), acting as a reservoir not only of water, but also of eggs and larvae of the estuarine aquatic fauna. During high tides, fish swim to the less saline water to spawn.
The juvenile fish grow in these estuarine waters, which are rich in nutrients due to the organic biomass supplied by the agricultural fields.
The adult fish that migrates back to more saline waters to be recruited to the adult stock is caught at the sluice gate during dark hours.
This practice ensures high yield while protecting fish and shrimp. Good-sized crabs can also be caught in traps.
The importance of the fish in this form of coastal management reconciling different needs is symbolised by local art work.
