Age and growth of Anguilla japonica sampled from the Qiulu River in southern China were studied. Mean body lengths and weights of the eels at each age were back‐calculated from their otoliths. The growth parameters for the von Bertalanffy function gave L ∞ = 98–2cm, K =0·07 and t 0 =− 1·94. Scales were observed to form firstly at the middle part of the lateral line, at a minimum body length of 160 mm and were inappropriate for ageing.
