Data on Dutch Fisheries on Salmon (1863-1957) and Trout (1886-1986) Fisheries in the River Rhine

摘要

Plans to reintroduce salmon (Salmo salar) in the Rhine River gave rise to the 'Ecological rehabilitation of the Rhine River' program. The program is a joint effort of the Ministries of Public Works and Transport of Agriculture and Fisheries and of Housing, Physical Planning and the Environment. A literature survey was carried out on the anadromous fish species, present or once inhabiting the Rhine River and Meuse-systems. The contribution deals with the salmon and trout (Salmo trutta). A complete run of catch data could be established for the salmon (1863-1957), and some indications on the period 1650-1805. A nearly complete run of catch data for the trout exists for the years 1886-1986. Still some trout are caught in the Rhine and Meuse. Indicated are the causes for the decline of both species, and the disappearance of the salmon, e.g., canalization, river-corrections, dams-sluices-weirs, gravel extraction, pollution.
