FISHERIES
Are buildings located on the banks
of the rivers specially designed for catching
salmon, lamprey, eels and shad. The most
common consist of ashlar block walls aligned
parallel to or across the river, where the currents
push the fish through narrow passages, among
which is a conical net (called a “boteirón” in the
Galician language), which is placed at the end
of the passages.
The first fisheries date from before the twelfth
century, traps made of wooden poles or simple
structures made by rearranging the river stones.
In the fifteenth century there is evidence of
more intricate constructions.
The progressive abandonment of these river
infrastructures, given that they were not
profitable, took them to the brink of extinction.
Only some buildings remained almost in their
original state, as is the case with the fisheries in
the Municipality of Arbo (Pontevedra).
Maybe some resources are not geo-referenced and they are not being displayed.
