Some remarks on eel management in lakes

The paper presents basic factors determining eel production in Polish lakes. Analysis of data from 582 lakes over 29 years (1950–1978) showed that ell yield in lakes is basically determined by the artificial stocking of eels. The relationship between eel catch and eel stocking is very close and to a certain extent independent of the fishing effort. Prospects of further development of eel management in Europe are presented, as well as basic problems facing this management on a general scale. A need is identified for further studies in this field.
