Fisheries sectors of Central and Eastern Europe and the Commonwealth of Independent States (CEECIS) countries have faced difficult times during the process of economic transition to the free market system. This Symposium brought together representatives from Government and the emerging private sector in the region to present their experiences and discuss the issues involved in a number of areas of common interest. The Symposium was organised by the Natural Resources Institute of the University of Greenwich, in collaboration with FAO EASTFISH, from funding provided by the UK Department for International Development. These Proceedings of a Regional Symposium for CEECIS Countries Opportunities and Constraints in the Development of Fisheries Enterprises present over 30 papers that focus on a number of key themes relevant to the development of viable fisheries enterprises. The six sessions cover Finance for Fisheries Enterprises; Business Management Training; Quality Assurance and Hygiene in Relation to International Trade Compliance; Total Quality Management and HACCP; The Marketing of Fish and Fish Products; and New and Added Value Product Development. Also included are the very positive discussions generated by the 53 participants representing 20 countries all but four of which were from the CEECIS region. The Proceedings will be of particular interest to fisheries managers of emerging developing enterprises and administrators involved in changing the roles and responsibilities of government to support the development of privately owned enterprises. The symposium has brought forward a series of new and challenging problems for enterprise managers and administrators in areas where they had little previous training or experience
