The paper presents a technological-spatial model of fishing harbour servicing simultaneously medium- and long-range fishing fleets; two alternate versions are considered: a single-basin and a two-basin approach. The main emphasis is placed to considerations on technological processes associated with services paid in connection with fish products, the concept covering all the operations devised to protect, preserve, and process fish raw materials from their discharge to dispatch. The paper may serve as a pattern on which to base the development of fishing ports, particularly in developing countries wishing to fully exploit their 200-mile economic zones.
