✦ Synopsis

Two series of indices, based on glass-eel fisheries data, are used: From 1977 onwards, average catch shows a decreasing trend, becoming moderate after 1982. Fisheries indicators (CPUE, iishing effort and total yield), estimated since 1985, demonstrate contrasting evolutions inside the Loire fishery, according to location (upstream/downstream zone) and to climate. The coastal recruitment of glass-eel is likely t o be less biased by catchability wriation.
