Description 
Summary

Time series of cod age composition in bi-annual catches from fixed periods (spawning season and autumn) with fixed gear, of fixed duration and at fixed positions in the Trondheimsfjord. Routine data collecting (for database) started in 1973, but relative yearclass strength is calculated back to 1963. The age data are processed until 1999, and the relative yearclass strengths estimates until 1997.
