Abstract
    1. The growth of Crangon crangon can be followed by counting the segments of the exopodite of the antennula (TIEWS, 1954). The frequency of moulting is a function of temperature. Knowing the growth at each moult (fig. 3) and the monthly mean temperature, a diagram for the growth of the shrimp could be reconstructed (fig. 4). (For more details, see TIEWS, 1954 and SCHOCKAERT, 1968).2. Same factors have been noted which are in contradiction with the sex-inversion (male into female), supposed by BODDEKE (1962) :-the way of growth;-the growth and shape of the endopodite of the first pleopode in males and females (fig. 6 and 7);-the appendix masculina is always present;-the occurance of spermatoza in males in the months of august and september.
