摘要：

The assessment of the stocks of North Sea Norway pout and sandeel has been inhibited by the absence of catch-al-age data in recent years. A statistical model for the analysis of seasonal cateh-at-age, effort, and research vessel abundance data is developed in which all the model parameters can be estimated even when some data are missing. The model is used to estimate the age compositions for the year when data are missing and recent stock trends. The results compare very closely with the last conventional assessment of these stocks. © 1993 Conseil International pour l’Exploration de la Mer.
