No hay salmones y, en consecuencia, no puede hacerse la tan esperada subasta (¿del último?) El tratamiento en prensa del camino acelerado hacia la extinción del salmón en la península ibérica es una verdadera vergüenza. Lamentable sin paliativos

Eels are long fishes so the chance of being hit by the turbine is higher. But this affects all fish that want to migrate downstream, it doesn't matter if it is for reproduction or feeding. There are mitigations that lower the risk for migrating fish.

From IUCN: 3,086 of 14,898 fw fishes are imperiled. If these spp are lost in the next 100 yrs (seems plausible), it would equal a rate of 1 extinction per 480 spp-yrs. The prehistoric rate for fw fishes is 1 per 3 million spp-yrs. The modern rate is 6000X higher. www.theguardian.com/environment/...

New article in Transactions: New insights into the expansion of an introduced lineage of kokanee in a large, impounded watershed, including the impacts of a widespread stocking program on native populations of kokanee in north-central British Columbia - read more (open access): bit.ly/3NcuhtX
Map of Williston Reservoir and associated reaches of the watershed in British Columbia. Red stars signify the original stocking locations of Columbia River-origin kokanee in the watershed (Langston 2012). Blue circles denote sampling locations for kokanee that spawned in tributary streams to the reservoir. Purple triangles represent locations where native kokanee were found in the Parsnip River reach; the pink triangle indicates native kokanee in the Finlay River reach. Orange circles are the approximate locations of within-reservoir sampling that occurred in 2000 (Pillipow and Langston 2002). Samples collected from the G. M. Shrum intake towers in 2016 and 2019 were from the site (orange circle) closest to the W. A. C. Bennett Dam.
