Salmon (Salmo salar L.) and trout (Salmo trutta L.) fishing and stocking in the lower Odra River system

Abstract

The paper presents and analyses the catches of salmon and trout in the Szczecin Firth and lower Odra River as well as in the rivers Warta and Noteć over the period of 1952-1972. The both species had to be treated jointly because such is the case with information given by the economic statistics available to the authors. A year-to year, between-season and between-region variabilities were considered. Fish caught by the German (GDR) fishermen were also taken into account. Additionally, the post-war data concerning the lower Odra stocking with salmon and trout are collected.
