In a preceding paper in 1980, the status of marine salmonid rearing in French coastal waters was described and the prospects analyzed. After a period of rapid increase in production (1976–1980) a plateau was reached, and in 1983 total marketed production remained below 450 metric tons. The major part of this production was composed of rainbow trout, with coho salmon and brown trout staying at a limited scale. The causes of this evolution and the possible ways of influencing further development of this activity are discussed. Among the major factors influencing production, environmental parameters (temperature, salinity), availability of juveniles, production costs of the marine phase and market acceptability are analyzed. We include a discussion about competition with marine aquaculture products of northern Europe and the emerging production of large size rainbow trout in freshwater in southern areas of France. The major inputs to be expected from research progress and their applicability to the production phase are discussed.
