A river turns into a trap<\/h2>\n\n\n\n
Field monitoring has shown this pattern before. In July 2024, while Acci\u00f3 Ecologista-Agr\u00f3 was carrying out its Emys project to monitor native turtles, the Canyoles stopped flowing through X\u00e0tiva and many remaining pools dried out. The ecological flow for August was reported at about 2.1 ft.\u00b3\/sec. between Canals and the Albaida.<\/p>\n\n\n\n
That number can sound abstract, but in the water it can mean survival or suffocation. When pools become cut off, temperatures rise and oxygen falls<\/a>, and trapped eels can die before the channel reconnects. Small pools become cages.<\/p>\n\n\n\n The European eel is not a normal river fish. It spawns in the Sargasso Sea, then its larvae drift toward Europe and North Africa before young eels<\/a> enter estuaries, wetlands, and rivers. Many spend 5 to 20 years growing in fresh or brackish water before trying to return to the sea to reproduce and die.<\/p>\n\n\n\n In practical terms, the eel needs a river that works like a corridor, not a staircase with missing steps. Dams, weirs, dry stretches, polluted water, and damaged wetlands can interrupt either half of the trip, leaving adults unable to reach the ocean or juveniles unable to climb upstream.<\/p>\n\n\n\n Here is the contradiction: Spain\u2019s Ministry for the Ecological Transition<\/a> tried again in 2026 to move the eel toward stronger national protection<\/a>, arguing for its inclusion as \u201cEndangered\u201d under Spain\u2019s protected species system. An April government response later said the February 17 meeting with regional governments ended with a \u201clack of necessary consensus\u201d and instead led to the creation of a working group.<\/p>\n\n\n\n Global conservation agencies are far less hesitant. The European Commission notes that the European eel is listed as \u201ccritically endangered\u201d on the IUCN Red List<\/a>, while the International Council for the Exploration of the Sea (ICES<\/a>) advises \u201czero catches\u201d in all habitats for 2026, including recreational and commercial fishing and glass eels used for restocking or aquaculture.<\/p>\n\n\n\n Drought is the visible cause in Valencia, but it is not the only pressure. Spain\u2019s agriculture ministry<\/a> lists dams, migration barriers, fishing, pollution, changing ocean currents, contaminants, viruses, and parasites among the threats that may be affecting the species. It also notes that large dams built from the 1960s onward helped push the eel out of much of the interior of the Iberian Peninsula.<\/p>\n\n\n\n Water quality adds another layer. Too many nutrients from farms can fuel algae growth, which burns through oxygen and makes life harder for fish already trapped in warm pools<\/a>. Then there is illegal trade, with the European Commission warning that poaching and illegal export to Asia remain additional concerns.<\/p>\n\n\n\n The debate is uncomfortable because eels are not just data points. In parts of Spain, including the Valencian region, eel fishing has cultural roots and local economic value. The ministry itself acknowledges that eel fisheries vary by autonomous community and are generally traditional in character.<\/p>\n\n\n\n Scarcity changes the math, though. The younger stage, known as glass eel or angula, can be especially valuable, and ICES says even those catches should fall to zero under the precautionary approach. At the end of the day, the question is not whether the eel matters to local culture, but whether that culture can survive if the animal keeps disappearing.<\/p>\n\n\n\n![\"European](\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/07\/european-eel-river-habitat-low-oxygen-drought-1024x576.jpg\")
