The growth of individual capelin in the Barents Sea stock was analysed in relation to the geographical distribution and size of the stock in the feeding season, and the density of fish in the feeding area. The growth in the current feeding season was estimated using a model of back-calculation of fish lengths from otolith zone widths. Stock size and fish density were estimated using bioacoustical methods. A strong correlation between the growth and the feeding area was found, while no dependence between growth and stock size or fish density could be demonstrated.
