Where can I buy fresh fish at wholesale prices in Almeria province

Only fishmarket i know is in Almeria. Fishmonger from Garrucha comes through the villages around Sorbas once/twice a week (Guevara is wednesdays)

I don't think you'll buy any fish at wholesale prices around here. 

Cheapest fresh fish is usually found at Mercadona.  The prices usually go up at weekends especially when there are tourists around.

In my part of Sorbas campo which is to the south, a fishmonger comes from Carboneras twice weekly but he tends to be more expensive.
