Review of sea trout fecundity

Data on the fecundity of sea trout from the British Isles, Norway and France are reviewed.



British Isles data are available for six stocks in England and Wales, three in Scotland and one in Ireland. The data were compared by use of a formula to link number of eggs per female with fish length for each stock, and for the stocks of each area. Comparisons are made based on predictions for fish of a range of standard lengths from 270 - 700 mm.
