Abstract
The paper presents the analysis of the stock of spurdog caught from the North Sea in 1974. The analyses cover length and age composition of the stock as well as percentage contributions of both sexes. The spurdog growth rate in terms of length and weight has been studied; fecundity and 1+ embryo length have been described as well. The conclusions concerning the stock protection against overfishing have been drawn.
