| GUIDELINES FOR STOCKING COREGONIDS |
PREPARATION OF THIS REPORT
This Occasional Paper was prepared in response to the recommendation of the European Inland Fisheries Advisory Commission (EIFAC) Working Party on Stocking, which recognized the need for guidelines for stocking coregonids, an important fish group in Europe. The valuable collaboration of Dr. M. Bninska (Poland), Dr. K. Salojarvi (Finland) and Dr. J. Banks (UK) in the preparation of these guidelines is gratefully acknowledged.

| ABSTRACT |
| These guidelines deal with three species: vendace (Coregonus albula), whitefish (C. lavaretus L. s.l.) and peled (C. peled). The transfer of whitefish and vendace has been practised for centuries and considerably extended the distribution area of coregonids in Europe. The present guidelines are based on practical experience and research work. Large-scale vendace stocking is practised in Poland and Finland, and whitefish and peled are stocked in many European countries. The guidelines give a scheme for planning coregonid stocking and management policies. Four major sections deal with ecological considerations, fisheries considerations, social costs and effects, and evaluation of the available information and methods. These guidelines are addressed mainly to fisheries managers and administrators in order to assist them in the development of efficient and economic stocking policies and practices. |
