Abstract 

During spring, in the period 1989-94, greater silver smelt (Argentina silus) was recorded along the shelf edge west of the British Isles. In some years, acoustic estimates of the concentrations were made, suggesting biomass values from 200 000-400 000 tons. In the period 1990-92, the size of greater silver smelt biomass recorded off mid-Norway in spring was also estimated, showing slightly higher values than the ones obtained west of the British Isles. In 1989, significantly less biomass was recorded in Norwegian waters during autumn than during spring. The geographical distributions of the recordings, as well as biological parameters, such as age, length and sex compositions, are examined. Growth relations are also discussed.
