Abstract | Catch data of coregonids (Coregonus albula, C. Lavaretus), notwithstanding that the species were abundant for many hundred years, dates only from 1910. In 1918 the commercial fishery came to an end. The highest recorded catch 14.6 tons was in 1915. Extensive restocking operations between 1907-1938 were all failures. At present still a few specimens are caught yearly from releases and re-stocking programs in West Germany. Migratory (anadromous) smelt (Osmerus eperlanus) was once an important fishery in the Zuiderzee and Rhine-Scheldt estuary. The fishery in the Zuiderzee came to an end in 1932 when the enclosure dam was completed. The smelt fishery in the lower reaches of the Rhine came to an end in 1966 when the 'delta-works' were completed in Hollands Diep and Haringvliet.
