Environmental Condition and Fauna
The banks of the river were intensely industrialized starting in the middle of the 19th century and later, so the river grew conspicuously polluted up to the 1980s, with almost all its river fauna becoming extinct. At that point, its environmental situation began to revert, the river showing currently a healthy condition. There exists an instable trout population downstream of Andoain, while other fish prevail and remain steady, i.e. Cyprinidae such as barbel (Barbus graellsi), ezkailu (Phoxinus phoxinus) and ray-finned fish (Chondrostoma toxostoma arrigonis). A stretch of the estuary by the village Aginaga is known for its baby eels, bred and harvested for human consumption before they grow up, providing for a much appreciated and dearly paid for culinary dish, while they were totally neglected just some decades ago.

Famous quotes containing the words condition and/or fauna:
“What I claim is to live to the full the contradiction of my time, which may well make sarcasm the condition of truth.”
—Roland Barthes (1915–1980)
“The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.”
—Louis Aragon (1897–1982)
