Distribution and habitat
Biology and ecology
Because of its rarity, little is known about the biology of the Ammersee kilch. Spawning occurs at the lake floor, 40–50 m (130–160 ft) in depth, in the summer, typically between June 15 and July 15.[5]
Human interaction
In the early 1900s, the Ammersee kilch was an important commercial species, but by the 1930s local fishermen considered it to be very rare. Pressure from commercial fishing combined with eutrophication starting in the 1950s led to steep population declines. Although the water quality of Lake Ammer increased in the 1970s due to drainage of local wastewater from the lake basin, the Ammersee kilch population never recovered.[4] Today, the Ammersee kilch is listed as Critically Endangered by the IUCN, and only three individuals have been caught since 2000.[1] Preserved specimens of the Ammersee kilch are also extremely rare. A 2005 study done to redescribe the species was only able to locate three specimens: two that were caught in 1951 and a third caught after a two-year search from 2002-2004.[4]
